8. Speakeasy - also called a blind pig or blind tiger, is an illicit establishment that sells alcoholic beverages. Such establishments came into prominence in the United States during the Prohibition era (1920–1933, longer in some states). During that time, the sale, manufacture, and transportation (bootlegging) of alcoholic beverages was illegal throughout the United States

9. Flappers- were a generation of young Western women in the 1920s who wore short skirts, bobbed their hair, listened to jazz, and flaunted their disdain for what was then considered acceptable behavior. Flappers were seen as brash for wearing excessive makeup, drinking, treating sex in a casual manner, smoking, driving automobiles, and otherwise flouting social and sexual norms. Flappers had their origins in the liberal period of the Roaring Twenties, the social, political turbulence and increased transatlantic cultural exchange that followed the end of World War I, as well as the export of American jazz culture to Europe.

10. Surrealism - Is a cultural movement that began in the early 1920s, and is best known for its visual artworks and writings. The aim was to "resolve the previously contradictory conditions of dream and reality".

11. Cubism - was one of the most influential visual art styles of the early twentieth century. It was created by. Pablo Picasso. (Spanish, 1881–1973) and Georges Braque (French, 1882–1963) in Paris between 1907 and 1914.

The leaders of the movement were Henri Matisse and André Derain.

14. Model T - is an automobile that was produced by Ford Motor Company from October 1, 1908, to May 26, 1927. It is generally regarded as the first affordable automobile, the car that opened travel to the common middle-class American; some of this was because of Ford's efficient fabrication, including assembly line production instead of individual hand crafting.

15. Harlem Renaissance - was the name given to the cultural, social, and artistic explosion that took place in Harlem between the end of World War I and the middle of the 1930s.

The separate Volstead Act set down methods for enforcing the Eighteenth Amendment, and defined which "intoxicating liquors" were prohibited, and which were excluded from prohibition (e.g., for medical and religious purposes). The Amendment was the first to set a time delay before it would take effect following ratification, and the first to set a time limit for its ratification by the states. Its ratification was certified on January 16, 1919, with the amendment taking effect on January 16, 1920.

21. 19th Amendment - to the United States Constitution prohibits any United States citizen from being denied the right to vote on the basis of sex. It was ratified on August 18, 1920. Until the 1910s, most states disenfranchised women. The amendment was the culmination of the women's suffrage movement in the United States, which fought at both state and national levels to achieve the vote. It effectively overruled Minor v. Happersett, in which a unanimous Supreme Court ruled that the Fourteenth Amendment did not give women the right to vote.

22. 21st Amendment - to the United States Constitution repealed the Eighteenth Amendment to the United States Constitution, which had mandated nationwide Prohibition on alcohol on January 16, 1919. The Twenty-first Amendment was ratified on December 5, 1933.

Both adhered to an anarchist movement that advocated relentless warfare against what they perceived as a violent and oppressive government.

26. Scopes Trial - was an American legal case in 1925 in which a substitute high school teacher, John Scopes, was accused of violating Tennessee's Butler Act, which had made it unlawful to teach human evolution in any state-funded school. The trial was deliberately staged to attract publicity to the small town of Dayton, Tennessee, where it was held. Scopes was unsure whether he had ever actually taught evolution, but he purposely incriminated himself so that the case could have a defendant.

27. Tea Pot Dome Scandal - was a bribery incident that took place in the United States from 1921 to 1922, during the administration of President Warren G. Harding. Secretary of the Interior Albert Bacon Fall had leased Navy petroleum reserves at Teapot Dome in Wyoming and two other locations in California to private oil companies at low rates without competitive bidding. In 1922 and 1923, the leases became the subject of a sensational investigation by Senator Thomas J. Walsh. Fall was later convicted of accepting bribes from the oil companies and became the first Cabinet member to go to prison. No person was ever convicted of paying a bribe

28. Al Capone - was an American gangster who attained fame during the Prohibition era as the co-founder and boss of the Chicago Outfit. His seven-year reign as crime boss ended when he was 33 years old.

Capone apparently reveled in attention, such as the cheers from spectators when he appeared at ball games. He made donations to various charities and was viewed by many to be a "modern-day Robin Hood". However, the Saint Valentine's Day Massacre of gang rivals, resulting in the killing of seven men in broad daylight, damaged Chicago's image—as well as Capone's—leading influential citizens to demand governmental action and newspapers to dub him "Public Enemy No. 1".

29. Warren Harding - was the 29th President of the United States, serving from March 4, 1921 until his death in 1923. At the time of his death, he was one of the most popular presidents, but the subsequent exposure of scandals that took place under his administration, such as Teapot Dome, eroded his popular regard, as did revelations of an affair by Nan Britton, one of his mistresses. In historical rankings of the U.S. presidents, Harding is often rated among the worst.

30. Calvin Coolidge - was the 30th President of the United States (1923–29). A Republican lawyer from Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of that state. His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. Soon after, he was elected as the 29th vice president in 1920 and succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small-government conservative, and also as a man who said very little, although having a rather dry sense of humor.

31. Marcus Garvey - was a Jamaican political leader, publisher, journalist, entrepreneur, and orator who was a proponent of the Pan-Africanism movement, to which end he founded the Universal Negro Improvement Association and African Communities League (UNIA-ACL). He also founded the Black Star Line, a shipping and passenger line which promoted the return of the African diaspora to their ancestral lands.

32. Zora Neale Hurston - Is considered one of the pre-eminent writers of twentieth-century African-American literature. Hurston was closely associated with the Harlem Renaissance and has influenced such writers as Ralph Ellison, Toni Morrison, Gayle Jones, Alice Walker, and Toni Cade Bambara.

Through her writings, Robert Hemenway wrote in The Harlem Renaissance Remembered, Hurston "helped to remind the Renaissance--especially its more bourgeois members--of the richness in the racial heritage."

33. Langston Hughes - was an American poet, social activist, novelist, playwright, and columnist from Joplin, Missouri.

He was one of the earliest innovators of the then-new literary art form called jazz poetry. Hughes is best known as a leader of the Harlem Renaissance in New York City. He famously wrote about the period that "the negro was in vogue", which was later paraphrased as "when Harlem was in vogue".

34. Louis Armstrong - was an American trumpeter, composer, singer and occasional actor who was one of the most influential figures in jazz. His career spanned five decades, from the 1920s to the 1960s, and different eras in jazz.

Coming to prominence in the 1920s as an "inventive" trumpet and cornet player, Armstrong was a foundational influence in jazz, shifting the focus of the music from collective improvisation to solo performance. With his instantly recognizable gravelly voice, Armstrong was also an influential singer, demonstrating great dexterity as an improviser, bending the lyrics and melody of a song for expressive purposes. He was also skilled at scat singing.

35. Duke Ellington - was an American composer, pianist, and bandleader of a jazz orchestra, which he led from 1923 until his death in a career spanning over fifty years.

Born in Washington, D.C., Ellington was based in New York City from the mid-1920s onward, and gained a national profile through his orchestra's appearances at the Cotton Club in Harlem. In the 1930s, his orchestra toured in Europe. Though widely considered to have been a pivotal figure in the history of jazz, Ellington embraced the phrase "beyond category" as a liberating principle, and referred to his music as part of the more general category of American Music, rather than to a musical genre such as jazz.
