By 1900, the population of New York City reached 3.5 million people as large numbers of immigrants arrived in the US, TR News magazine reported. Many newly arrived residents lived in tenement districts within walking distance of the factories or sweatshops where they worked.

While New York City's elevated railroad began operating in 1868, the subway system was built between 1900 and 1936, with the first underground railway opening in 1904.

The underground trains helped relieve congestion above ground and expand the distance from which people could commute to work.

The subway cost five cents per ride — lower than today's fare of $2.90.

Some subway tunnels were built using a method called "cut and cover" in which workers cut trenches into the street and built temporary wood structures over the hole to allow for the continued flow of traffic, according to the New York Transit Museum. The construction of deeper tunnels required the use of dynamite.

The ferry routes became obsolete as more bridges were built, allowing cars to cross New York City's waterways. Out of the dozen or so ferry routes that operated in the 1920s, the Staten Island Ferry remains the only free ferry service provided by the city, according to the New York City Department of Records and Information Services.

Chicago's first elevated railroad opened in 1892, and the Union Elevated Railroad connecting all four lines was completed in 1897, according to the Encyclopedia of Chicago.

The city's first subway didn't open until 1943.

The population of Chicago was around 2.7 million in 1920, according to US Census data.

In the 1920s, women often wore flapper dresses and cloche hats, while men wore suits and fedoras.

Operated by the Pacific Electric Railway, the red streetcars provided interurban service to the greater Los Angeles area, leading to the development of suburbs in the nearby Orange, San Bernardino, and Riverside counties.

At its peak ridership of 3.1 million passengers in 1924, the Pacific Electric Railway operated 2,100 trains a day across 1,100 miles of track in the greater Los Angeles area, Pasadena Weekly reported, citing data from the Electric Railway Historical Association of Southern California.

Pacific Electric Railway's streetcar service shut down fully in 1961.

On August 18, 1920, the 19th Amendment was ratified, granting women the right to vote. However, the law largely applied to white women, as Black women, Indigenous women, and other women of color were prohibited from voting for many decades to come.

Here, a photographer captured celebrations after the newly ratified 19th Amendment in August 1920.

With the rise in women's liberation movements came a wave of modernist short hairstyles.

In the Roaring Twenties, fashion was characterized by fringe, loose fabrics, and glamorous details. The garments differed immensely from the athleisure and street style-inspired looks that fill clothing racks today. But as fashion historians explain, trends are cyclical — '20s-inspired clothes could (and will likely) make a comeback into mainstream fashion again.

Prior to the 1920s, women's bathing suits often included stockings and full-length skirts.

With an increase in popularity in water activities, the decade saw a rise in swimwear fashion styles with less fabric, making it more comfortable for wearers to swim.

Brides Magazine reported that beaded headbands were common additions to wedding gowns during the Jazz Age, as were dresses with high necklines and cape- or flutter-style sleeves.

The 1920s are often looked at as one of the most influential decades of automobile advancements.

The Model T was sold by the Ford Motor Company 1908 until 1927, per History.com. The vehicle was the earliest effort to make a modern car that was affordable to the masses.

As explained by the History Channel, the Model T was so affordable that it helped rural Americans connect to other parts of the country, which eventually led to the creation of the numbered highway system that's known throughout the US today.

Here, a woman was photographed outside a cab vehicle in Los Angeles, circa 1925.

The US Census Bureau reported that the 1920 census marked the first time over 50% of Americans reported living in urban areas compared to rural ones.

Pictured here is a subway entrance in London, circa 1924. Transport for London reported that the city's Underground was the first subway in the world, having opened in 1863.

Here, a group of employees stand in front of a train in 1920.

Train travel was arguably its most glamorous from 1910 through 1950.

Here, a group of people wait to board a bus in Chicago around 1925.

Here, members of a fire department in Pittsburgh, Pennsylvania, were photographed around 1920.

Here, passengers onboard the Saturnia ship partake in an evening dance in the 1920s. The Saturnia was an Italian liner that sailed until the 1960s. Along with its sister ship, Vulcania, it was among the first large transatlantic liners driven by diesel engines, the Italian Liners Historical Society reported.

Prohibition went into effect in 1920 with the 18th Amendment. Until it was repealed in 1933, the law greatly impacted American culture and society, giving way to organized crime and speakeasies.

Here, people drink at a speakeasy around 1920.

Drugstores weren't just places to grab quick convenience items like they are today; they were central gathering spots in the community. At a 1920s-era pharmacy, customers could sit at the counter and enjoy a root beer float or an egg cream.

These pharmacies of a bygone era were much more ornately decorated — with marble countertops and beautiful light fixtures — than the fluorescent lighting-clad drugstores of today.

General stores became less common after the 1920s, but throughout the decade, they were still popular for various goods for farmers and industrial workers, as well as equipment and food.

At the time, classrooms and schoolhouses were designed to hold as many students as possible to maximize space.

But in the 1920s, more educators and administrators started to support "progressive" schools that were built to house programs that were new at the time, allowing more open-air, light, and access to outdoor activities, per a 2012 report from the National Institute of Building Sciences about school design.

Here, the Queen — then known as Princess Elizabeth — was pictured in 1929 at a train station, apparently on the way to the family's Sandringham Estate for Christmas.

He was born on January 15, 1929, in Atlanta and became one of the most important figures in the Civil Rights Movement during the '50s and '60s.

Here, two people photographed around 1926 do the Charleston dance.

Per the Charleston County Public Library, it became a mainstream dance after the musical's release in 1923 and defined the rest of the decade.

Jazz music dominated 1920s culture in America thanks to popular musicians like Louis Armstrong.

The National Museum of African American History and Culture reported that after the end of the Civil War, the Great Migration brought over 100,000 Black Americans from a wide variety of backgrounds to Harlem, New York City.

Throughout the 1920s and '30s, Black creatives across disciplines shared their art en masse, documenting what it was like to be Black in America during a period known as the Harlem Renaissance.

Iconic works from the likes of Nella Larsen, W.E.B. Du Bois, Zora Neale Hurston, and more were all produced during this era.

In the photo above, the waiting room on the right was designated for "Colored" individuals while that on the left was for white people.

Segregation was a prominent aspect of life in the US following the Civil War, especially in the South where Jim Crow laws were harshly enforced.

Immigration from Japan to the US was largely limited during the 1920s as a result of the 1907 Gentlemen's Agreement.

However, it had an exception for Japanese wives of current American residents, which led to the practice of American men choosing Japanese women to be their wives solely based on photos.

Many of the Japanese "picture brides" faced discrimination, spousal abuse, and poor living conditions upon arrival to the US, Women & the American Story reported.

Such marriages were made illegal by the 1924 Immigration Act, which barred any immigrant who wouldn't be eligible for citizenship from coming to the US.

People of Asian descent were denied full US citizenship until the 1950s.

After the 1916 Olympic Games were canceled due to World War I, the 1920 summer Olympics were set in Antwerp, Belgium, as a way to honor "the suffering that had been inflicted on the Belgian people during the war," the Olympics reported.

It was also the first year the Olympic Rings symbol was publicly displayed.

Here, people carry newly manufactured tennis balls.

Pictured here, a football team poses in sporting uniforms at Oliver High School in Kentucky in 1921.

This looks way more sophisticated than a sweaty game of kickball.

Here, people attend a horse race at Ascot Racecourse in Ascot, England, around 1920.

Carnivals and state and county fairs in the US were popular summertime activities during the early 20th century.

USA Today reported that Coney Island's Luna Park is believed to have had one of the first bumper car attractions.

Coney Island was an iconic part of the early 20th century that transformed how Americans spent their free time.

The Brooklyn park gave locals and visitors new ways to stay entertained and spend time with one another in the form of roller coasters and rides, animal exhibits, and a lively boardwalk and beach.

Miss Coney Island 1924 and 1925, respectively, appeared to stand on the Coney Island boardwalk sometime during the mid-1920s.

This snapshot from around 1920 shows fair attendees having their picture taken.

Around 1920, a family was photographed at a beach in Germany holding up shrimping nets.

The National Endowment for the Humanities reported that the silent film era began in 1894 and continued through the 1920s. Before there were "talkies," audiences were dazzled by films starring actors like Charlie Chaplin and Clara Bow.

In 1927, "The Jazz Singer" became the first feature-length movie to feature dialogue scenes, marking a transition from the silent film era, per the Museum of Modern Art.

The World reported that the first film (that wasn't a feature-length movie) with talking scenes was actually created in 1898 by Alice Guy-Blaché.

Musical movies produced in the late 1920s, like "Broadway Melody," continued to push "talkies" into the mainstream.

The Dolly Sisters, pictured here, were famous vaudeville performers in the early 20th century.

Another iconic vaudeville production during the 1920s was the Ziegfeld Follies, PBS reported, which preceded the modern Broadway musical and helped launch the career of many theatrical stars of the time.

MGM's first lion named Leo was shown on screen in 1927, per The Hollywood Reporter.

In the almost 100 years since this photo was taken, some states in the US have banned the use of animals in circuses, while others have enacted partial bans.

The famous Ringling Bros. and Barnum & Bailey circus show, "The Greatest Show on Earth," shut down in May 2017 after 146 years of shocking the nation with its acrobatic and animal performances. It reopened five years later, but without animals.

Here, women are photographed holding pigs outside of a circus in New York around 1920. 

Willis Carrier invented the first air conditioner in 1902, but it wasn't until 1929 that Frigidaire introduced a unit that was suitable for use in homes, the US Department of Energy reported.

People relied on newspapers for local, national, and global updates, as well as advice columns, entertainment, and other stories.

The Pennsylvania Center for the Book reported that Pittsburgh radio station KDKA produced the world's first radio broadcast on November 2, 1920.

Frank Conrad is known as the "father of radio broadcasting" for inventing the first station, which was located in his garage.

Per MIT Black History, Rufus P. Turner was the first Black radio station operator. He began operating his station, W3LF, in Washington, DC, in 1928.

Phones of the 1920s and '30s were characterized by their rotary dials and "spit cup" receivers.

Being a switchboard operator often required saying the phrase "number please" hundreds of times per hour for eight hours a day, according to a 1922 op-ed in The New York Times, as cited by Time.

The beginning of the 20th century brought many advancements to the home — from gas ranges to the advent of refrigerators, which became commonplace in homes by the 1920s — but kitchens certainly didn't have the multi-functional, high-tech gadgets many homes are equipped with today.

Here, kids were photographed at a soda stand on a street in Paris around 1920.

The only thing that would make this sweeter was if Coca Cola still cost a nickel.

Here's to all the changes and all the lasting pleasures of the next 100 years.

In the US, the earliest car manufacturers were metalworkers, blacksmiths, and the makers of bicycles and carriages, according to the Smithsonian National Museum of American History.

The cars were powered by electric, steam, and gas.

By 1910, Henry Ford had introduced the next model of his in-demand automobile, the Model T, and William Durant had founded his company, General Motors, per History.com.

Henry Ford had big plans for improving how his cars were manufactured, so he constructed a new plant in Highland Park, Michigan, in 1910, helping to establish the state as the industry's home, according to the company's history.

At his plant, Ford innovated mass-production techniques with his moving assembly line, which was first used in 1913.

His innovation was inspired by conveyor belts he'd seen in grain warehouses and assembly lines in slaughterhouses, according to Ford's website.

The vehicle was initially pulled into place by a rope — later, a chain — so the car could be built step-by-step.

With the moving assembly line, his Model T could be built in only 93 minutes, a dramatic decrease from the 12 hours it previously took, according to Ford.

The innovation also made employees' jobs more repetitive and tedious — like those pictured making flywheels — and they began quitting in droves.

In 1914, Ford doubled wages to $5 per eight-hour day, which is about $150 in today's money, per The Bureau of Labor Statistics. This competitive wage and its impact on productivity helped the middle class thrive, NPR reported.

A shorter workday also allowed Ford to create a third shift, and the plant was able to hire more workers and essentially make the company a 24-hour operation, according to Ford.

By 1926, the Ford Motor Company would become one of the first companies in the US to implement a five-day, 40-hour work week in its factories, History.com reported.

Ford halted production of its Model T in 1927, by which time 15 million units had been sold.

By the 1920s, Ford, Chrysler, and General Motors — all founded in Michigan — would be known as the Big Three automakers.

By 1929, the Big Three were responsible for 80% of the industry's output, History.com reported.

By the 1930s, smaller manufacturers were going out of business, unable to keep up with the large-scale production of the Big Three.

Photos from the 1930s show how the production line continued to thrive in America's car factories. That decade, European car makers adopted the same processes.

More than 6 million women stepped up in response to the shortage of male labor during World War II. In the car industry, the population of female employees increased from 28,300 in October 1941 to 203,300 by November 1943, according to The University of Michigan-Dearborn.

Here, workers are putting the finishing touches on the 1947 models of the Mercury, one of three cars made by Ford at the time, at the River Rouge Complex in Dearborn, Michigan.

That year, the company employed over 120,000 people in the US, according to the company's annual reports.

Ford workers in Dearborn, Michigan, are photographed finishing the Custom Deluxe at the end of the assembly line, which could produce 500 cars in a single, eight-hour shift.

In 1955, General Motors, Chrysler, American Motors (Nash-Hudson), Ford, and Studebaker-Packard were making 99.7% of all cars, The Saturday Evening Post reported.

In the 1960s and 1970s, the practice of importing foreign-manufactured cars began to rise. The trend continued through the end of the century and until today, when nearly half of cars purchased in the US are imports from foreign countries, as reported by the BBC.

The women's rights movement reached a national scale after the 1848 Seneca Falls Convention, in which leaders Elizabeth Cady Stanton and Lucretia Mott spoke on the need for women's suffrage. 

When the 19th Amendment was ratified in August 1920, it largely benefited white women.

Voter intimidation and discriminatory policies kept many Black women from the polls. The government also often denied Native American and Asian-American women citizenship, so they were also unable to vote. It wasn't until the Voting Rights Act of 1965 and voting rights amendments in 1975 that some Black women and other women of color were finally able to cast their ballots.

Women protested for their right to vote for nearly a century before the amendment was finally passed in 1920.

Those who protested faced arrest, jail time, and harassment in their efforts to secure women's rights.

They voted in the 1920 election for either Warren G. Harding and Calvin Coolidge on the Republican ticket or James Cox and Franklin Delano Roosevelt on the Democratic ticket. Harding won by a landslide and became president in 1921.

Women's suffrage in Great Britain was put into law differently than in the United States, The Independent reported. The country saw two stages of granting women the right to vote: the 1918 declaration of suffrage for women, and then the declaration of full suffrage for women in 1928.

The 1918 declaration was highly exclusionary, only allowing women over the age of 30 who were married to members of their local government register.

It was only in 1928 that women were granted equal voting rights to men, allowing women over the age of 21 to cast a ballot.

Though the Women's Christian Temperance Union was behind the movement that sparked Prohibition, there were also women against the alcohol ban.

Female bootleggers were often far more successful than men at the time, reported "Whiskey Women" author Fred Minnick, because it was illegal for male officers to search women.

In addition to using devices like this, women would hide bottles of liquor in their socks or under their jackets to smuggle alcohol.

Prohibition lasted nationwide from 1920 to 1933, but that didn't stop these ladies from enjoying a drink in 1925.

Georgia Ann Hill Robinson was the first Black female police officer appointed to the Los Angeles Police Department, and possibly the country, in 1916. She worked for the LAPD for 12 years, and fought against segregation and for women's welfare.

Before the job became popular for women, teenage boys worked as the first switchboard operators, History.com reported. However, they reportedly proved to be too rude and unruly, and bosses brought in women instead, believing them to be naturally more polite and soft-spoken.

World War I saw the first time that factory jobs, previously viewed as male positions, were taken over by women in the US.

Women began doing all sorts of jobs in the 1920s, per CCSU. They ran drill presses, did welding, operated cranes, used screw machines, and many other jobs that required heavy machinery.

These women spent their days weighing and packing candies in York, England.

In the 1920s, farms still didn't have electricity, plumbing, or heating and cooling, PBS reported. Despite the hardship, families in the Midwest focused on growing fruits and vegetables, while also producing eggs and meat.

Farmers across the US struggled to make a profit throughout the 1920s as a result of overproduction and the subsequent drop in prices. With farmers unable to pay their debts, "between 1920 and 1932, one in four farms was sold to meet financial obligations," the Library of Congress reported.

As pictured above, many Black women in the South picked cotton to make ends meet. 

A study indicated that two in three Black women from Black landowning families were involved in cotton farming in the 1920s.

Black women were often barred from working in the same jobs as white women, like these construction workers pictured above.

Segregation, both de jure and de facto, continued to exist into the 1960s and we can still see its legacies today.

The Louisiana lumber boom lasted from about 1880 to 1925, resulting in 4.3 million acres of trees being cut down, the Louisiana Forestry Association reported.

Henrietta Vinton Davis established the Black Cross Nurses in 1920 as a part of the Universal Negro Improvement Association and African Communities League. They offered health services and hygiene education to Black members of the community.

At the time, hardly any nursing programs would admit people of African descent and many health facilities provided unequal care to Black patrons, an issue that persists today especially in maternal health care. The Black Cross Nurses became key figures for civil rights.

In early 1921, the Greenwood District of Tulsa, Oklahoma was home to an affluent Black community who ran newspapers, churches, and scores of businesses and was known as the "Black Wall Street." By June 1, it would largely be burned to the ground in "the single worst incident of racial violence in American history," per the Oklahoma Historical Society.

Although the exact details remain lost to history, it's believed that on May 30, 1921, a Black man named Dick Rowland stepped on the foot of a white woman named Sarah Page when he entered the elevator of the Drexel Building. Page screamed and the town quickly exaggerated their tellings of the incident, leading to an attempted lynching of Rowland that night.

An altercation at the courthouse led the unsuccessful, angry members of the white mob to riot and attack Black people and their businesses. The Tulsa Historical Society and Museum reported that 35 city blocks were burned down in the attacks, possibly killing as many as 300 people and injuring more than 800.

In 1918 and 1919, there was a surge in protests at textile mills in Japan, where women demanded shorter working hours and wage increases. They were receiving far less money than their male counterparts, and they were doing important work like constructing war uniforms, for which there was huge demand at the time.

Though women were perceived as cooks, the role was relegated to the home, rather than a restaurant. However, the 1920s began to see women studying to be professional chefs.

Though the first practical dishwasher was invented in 1886 by Josephine Cochrane, The Independent reported, they did not become popular in homes until the 1920s.

The introduction of permanent plumbing in homes made machines like dishwashers possible, though they were expensive and only found in the homes of wealthy families.

In 1909, 22-year-old Alice Ramsey (not pictured) became the first woman to drive across the continental United States, in part to prove that women were capable behind the wheel, the Smithsonian reported.

These women are seen cooling down on a block of ice on a hot summer day. Bikinis were not yet popularized, so these outfits were likely the most skin women in the 1920s would be seen showing.

The 1920s was the first decade to see free and unbridled movement on many dance floors. Dances called the Charleston, the Black Bottom, and the shimmy were all highly popular. 

Women who went dancing at late-night parties were referred to as "good time girls."

The National Women's History Museum reported that Baker first became known in the US for her Vaudeville shows, but she really became a star when she moved to Paris. Baker's shows became famous for her African-inspired dance moves, her singing, and her elaborate costumes.

She was a key figure in the French Resistance during World War II as well as an activist for civil rights in the US. Although she died in 1975, Baker became the first Black woman to be buried in France's Panthéon, the country's highest honor, in 2021.

The Oscars described Pickford as the definition of a "movie star," known best for her work throughout the silent film era with movies like "Rebecca of Sunnybrook Farm," "Stella Maris," "My Best Girl," and "Sparrows."

She was a founding member of the Academy of Motion Picture Arts and Sciences and in 1930 was the recipient of the second Oscar for best actress.

She starred in the first best picture winner, "Wings," alongside Charles Rogers and Richard Arlen, and was widely known as a popular movie star throughout the decade.

You may also recognize her name from Taylor Swift's 2024 album, "The Tortured Poets Department," which had a song titled "Clara Bow."

Wimbledon opened its famous courts to women in 1884. Here, American Helen Wills competed against Brit Kitty McKane in the 1924 Ladies' Singles Final.

Though modest by today's standards, French tennis star Suzanne Lenglen, right, was known for her provocative style on display above.

The International Tennis Hall of Fame reported that Lenglen was first female player to forgo bulky undergarments and was known for wearing tops that displayed her bare arms and silk dresses that were trimmed above her calf. Coupled with painted nails, red lipstick, bobbed hair, a tendency to drink alcohol between sets, and a winning record, Lenglen was "a rare and fascinating champion."

The first swimsuits were actually made of wool, as other materials like nylon and elastane weren't yet invented.

It wasn't until the 1920s that tanning became popular. The Guardian reported that fashion designer Coco Chanel "may have inadvertently" created the trend with a photo showing her stepping off a cruise ship in Cannes after too much sun. The image was in every paper and created a new standard of beauty.

Stretching, rather than vigorous exercise, was viewed as the ideal method for women's bodies and health, Byrdie reported.

Stationary bikes and rowing machines were also invented in the 1920s, along with the Vibro-Slim, a machine with a vibrating belt that was meant to reduce belly fat.

Before the mechanical bull became a fun attraction at a bar, it was invented to train rodeo competitors. In the 1920s, it became a popular exercise fad after women realized it could help tone their abs and strengthen their core.

Here, movie star Helen Chadwick used the rowing machine to stay fit. 

With New York Yankees stars like Babe Ruth and Lou Gehrig, it's no surprise that the sport attracted the attention of both men and women in the city.

Women would go on to make their mark in baseball in the following decades, with 60 playing in the All-American Girls Professional Baseball League during World War II, the National Baseball Hall of Fame reported.

Women's swimming was the first aerobic sport accepted by the International Olympic Committee, according to USA Swimming, and was first introduced at the 1912 Olympics in Stockholm.

Pictured are US Olympic swimmers Aileen Riggin, Gertrude Ederle, and Helen Wainwright.

Bleibtrey won all three women's swimming races, including the 100-meter freestyle, 4x100-meter relay, and the 300-meter freestyle, per the Olympics.

Just one year prior, she had been arrested at Manhattan Beach for taking off her stockings before swimming, an act considered "nudity." However, outrage from her arrest sparked a change in "acceptable" swimwear — women no longer had to wear stockings — and Bleibtrey was not penalized.

After graduating from Cornell University with a degree in classical languages in 1905, Fauset spent time as a teacher before turning to writing in 1912.

Poets.org reported that she wrote poems, essays, and reviews for the NAACP's magazine, The Crisis, for seven years before becoming literary editor.

During the 1920s, Fauset introduced the world to legendary writers like Langston Hughes, Claude McKay, and Anne Spencer while also publishing her own novels "There Is Confusion" and "Plum Bum."

Lil Hardin Armstrong (pictured above) was just one of many women who would influence jazz music from the 1920s on.

The New York Times reported that Hardin helped her future husband Louis Armstrong become band leader of King Oliver's Creole Jazz Band; she also served as his first manager and was a pianist and frequent co-composer.

The National Museum of African American History and Culture reported that Smith was mentored by "Mother of the Blues," Ma Rainey, who taught her how to navigate the music industry and capture an audience's attention. Smith signed a record deal with Columbia Records in 1923, releasing "Down-hearted Blues," a major hit.

Smith became the highest-paid Black entertainer of the time and she recorded with iconic jazz musicians like Sidney Bechet and Louis Armstrong.

The Great Depression caused Smith's career to be cut short, and she later died from injuries sustained in a car accident in 1937.

1920s female fashion was characterized by loose fabrics, lots of fringe, and glamorous jewelry and details. Hair cut short into a bob was also popular, as seen in the woman above.

Long, straight skirts with low waists were the dominant style.

The loose skirts and dresses were very different from the constricting clothes of the previous decades, and were far more movable and comfortable.

Art Deco style and Gatsby-esque outfits were also popular for 1920s women. Showgirls and Vaudeville performers would dress up in decadent velvet and satin dresses, with pearl and gem details throughout.

Zelda was a major influence on Scott's writing, with the couple drawing lots of public attention throughout the 1920s. A writer and painter, too, Zelda's first and only novel, "Save Me the Waltz," was released in 1932.

Unfortunately, her life was largely cut short after being diagnosed with schizophrenia (now understood as bipolar disorder) and committed to sanatoriums. She died at age 47.

Though they were popularized 100 years ago, there are plenty of vintage outfits like these that are still trendy today.

1920s Halloween costumes were more about inspiring fear than dressing up as celebrities and TV characters. Clowns, ghosts, and witches were all highly popular costume choices back then.

Elizabeth Arden helped popularize makeup — once believed to be exclusively for movie stars —for the masses in the early 1920s. Arden started a marketing campaign that helped create the idea that wearing makeup was "appropriate and even proper," per the Library of Congress.

By 1925, Arden had salons open around the world in cities like New York, Paris, and London.

Beauty companies even made stencils, like the one above, to help women achieve the perfect Cupid's Bow.

Though the first nail salon in the US was opened in the late 1870s, nail polish began to really take off in the 1920s, Byrdie reported, thanks to the work of brands like Cutex and what would later become known as Revlon.

Wedding dresses followed the 1920s style: They were short, like the flapper dresses, with form-fitting bucket hats.

It used to be popular to have weddings on Christmas Day in Britain, as churches would hold nuptials for brides and grooms every year. It was often the only time that working class couples could get married, as they'd have Christmas and Boxing Day off.

The 1907 Gentlemen's Agreement limited immigration from Japan to the US, but it had an exception that Japanese wives of current American residents could enter the country. This exception started a system where men would choose Japanese wives based on their pictures alone.

These "picture brides" immigrated between 1907 and 1924, and faced many hardships. Many of their husbands were older and poorer than the women anticipated, and the wives faced spousal abuse in addition to societal racism fueled by anti-Asian sentiments, Women & the American Story reported.

The 1924 Immigration Act ended the practice, as it barred any immigrant "who by virtue of race or nationality was ineligible for citizenship," per the US State Department. People of Asian descent were denied full citizenship based on laws dating from 1790 and 1870.

In 2015, the Pew Research Center reported that in the 1920s, the US government enacted quotas reducing the number of immigrants granted entry. The first quota on immigration was passed in 1921 and allowed only 350,000 total immigrants; this was decreased to 165,000 in 1924. Nationality quotas were also imposed on Europeans.

The quotas were largely fueled by xenophobic fears toward Southern and Eastern European migrants, who'd come to the US during the second wave of migration from 1890-1919.

Meanwhile, immigration from most countries in Asia was already prohibited.

Prior to the passage of the Immigration and Nationality Act, passed in 1965, 70% of the quota visas available belonged to residents of Ireland, Germany, and the UK, the Pew Research Center reported.

Women of the Osage Nation were among those targeted and killed by William K. Hale and his accomplices in the early 1920s.

The Osage Nation reported that Hale and his associates are believed to be connected to more than 20 killings, though there were more than 60 murders total from 1920 to 1925. The killings were motivated by Hale's desire to inherit money held by the Osage people from the oil boom.

The tragedy was the subject of Martin Scorsese's Oscar-nominated film "Killers of the Flower Moon."
