• The Holocaust, also known as The Shoah (Hebrew: {{lang|he|השואה}}, Latinized ha'shoah; Yiddish: {{lang|yi|חורבן}}, Latinized {{transliteration|yi|churben}} or {{transliteration|yi|hurban}}[https://www.britannica.com/EBchecked/topic/269548/Holocaust "Holocaust," Encyclopædia Britannica, 2009]: "the systematic state-sponsored killing of six million Jewish men, women, and children and millions of others by Nazi Germany and its collaborators during World War II. The Germans called this "the final solution to the Jewish question ...") is the term generally used to describe the genocide of approximately six million European Jews during World War II, a program of systematic state-sponsored extermination by Nazi Germany, under Adolf Hitler, its allies, and collaborators.Niewyk, Donald L. The Columbia Guide to the Holocaust, Columbia University Press, 2000, p. 45: "The Holocaust is commonly defined as the murder of more than {{formatnum:5000000}} Jews by the Germans in World War II." Also see "The Holocaust", Encyclopædia Britannica, 2007: "the systematic state-sponsored killing of six million Jewish men, women and children, and millions of others, by Nazi Germany and its collaborators during World War II. The Germans called this "the final solution to the Jewish question". Some scholars maintain that the definition of the Holocaust should also include the Nazis' systematic murder of millions of people in other groups, including ethnic Poles, the Romani, Soviet civilians, Soviet prisoners of war, people with disabilities, gay men, and political and religious opponents.Niewyk, Donald L. and Nicosia, Francis R. The Columbia Guide to the Holocaust, Columbia University Press, 2000, pp. 45–52. By this definition, the total number of Holocaust victims is between 11 million and 17 million people.Donald Niewyk suggests that the broadest definition, including Soviet civilian deaths, would produce a death toll of 17 million. [https://books.google.com/books?id=lpDTIUklB2MC&pg=PP1#PPA45,M1] Estimates of the death toll of non-Jewish victims vary by millions, partly because the boundary between death by persecution and death by starvation and other means in a context of total war is unclear. Overall, about 5.7 million (78 percent) of the 7.3 million Jews in occupied Europe perished (Gilbert, Martin. Atlas of the Holocaust 1988, pp. 242–244). Compared to five to 11 million (1.4 percent to 3.0 percent) of the 360 million non-Jews in German-dominated Europe. Small, Melvin and J. David Singer.

Although the 1940s was a decade dominated by World War II, important and noteworthy films about a wide variety of subjects were made during that era. Hollywood was instrumental in producing dozens of classic films during the 1940s, several of which were about the war and some are on most lists of all-time great films. European cinema survived although obviously curtailed during wartime and yet many films of high quality were made in the United Kingdom, France, Italy, the Soviet Union and elsewhere in Europe. The cinema of Japan also survived. Akira Kurosawa and other directors managed to produce significant films during the 1940s.

Polish filmmakers in Great Britain created anti-nazi color film Calling Mr. Smith (1943) about current nazi crimes in occupied Europe during the war and about lies of nazi propaganda.{{Cite web|url=https://www.centrepompidou.fr/fr/ressources/oeuvre/cAXbMp|title=Calling Mr Smith|website=Centre Pompidou|access-date=2021-02-13|archive-date=2021-02-21|archive-url=https://web.archive.org/web/20210221202910/https://www.centrepompidou.fr/fr/ressources/oeuvre/cAXbMp|url-status=dead}}

Film Noir, a film style that incorporated crime dramas with dark images, became largely prevalent during the decade. Films such as The Maltese Falcon and The Big Sleep are considered classics and helped launch the careers of legendary actors such as Humphrey Bogart and Ava Gardner. The genre has been widely copied since its initial inception.

In France during the war the tour de force Children of Paradise directed by Marcel Carné (1945), was shot in Nazi occupied Paris.{{Cite web|url=http://www.filmreference.com/Films-Dr-Ex/Les-Enfants-du-Paradis.html|title=Les Enfants du Paradis - Film (Movie) Plot and Review - Publications|website=www.filmreference.com}}{{cite web |url=http://www.eufs.org.uk/films/les_enfants_du_paradis.html |title=Les Enfants du Paradis |website=www.eufs.org.uk |url-status=dead |archive-url=https://web.archive.org/web/20090113153911/http://www.eufs.org.uk/films/les_enfants_du_paradis.html |archive-date=2009-01-13 }} Gio MacDonald, Edinburgh University Film Society program notes, 1994–95{{Cite web|url=http://rogerebert.suntimes.com/apps/pbcs.dll/article?AID=/20020106/REVIEWS08/201060301/1023|title=Quoted by Roger Ebert, Children of Paradise, Chicago Sun-Times, 6 January 2002 review of the Criterion DVD release|access-date=27 December 2021|archive-date=20 September 2012|archive-url=https://web.archive.org/web/20120920084900/http://rogerebert.suntimes.com/apps/pbcs.dll/article?AID=%2F20020106%2FREVIEWS08%2F201060301%2F1023|url-status=dead}} Memorable films from post-war England include David Lean's Great Expectations (1946) and Oliver Twist (1948), Carol Reed's Odd Man Out (1947) and The Third Man (1949), and Powell and Pressburger's A Matter of Life and Death (1946), Black Narcissus (1946) and The Red Shoes (1948), Laurence Olivier's Hamlet, the first non-American film to win the Academy Award for Best Picture and Kind Hearts and Coronets (1949) directed by Robert Hamer. Italian neorealism of the 1940s produced poignant movies made in post-war Italy. Roma, città aperta directed by Roberto Rossellini (1945), Sciuscià directed by Vittorio De Sica (1946), Paisà directed by Roberto Rossellini (1946), La terra trema directed by Luchino Visconti (1948), The Bicycle Thief directed by Vittorio De Sica (1948), and Bitter Rice directed by Giuseppe De Santis (1949), are some well-known examples.

In Japanese cinema, The 47 Ronin is a 1941 black and white two-part Japanese film directed by Kenji Mizoguchi. The Men Who Tread on the Tiger's Tail (1945), and the post-war Drunken Angel (1948), and Stray Dog (1949), directed by Akira Kurosawa are considered important early works leading to his first masterpieces of the 1950s. Drunken Angel (1948), marked the beginning of the successful collaboration between Kurosawa and actor Toshiro Mifune that lasted until 1965.File:Frank Sinatra in Till the Clouds Roll By.jpg gained massive popularity during the decade, becoming one of the first teen idols, and one of the pop artists who sold the most records in the 1940s]]

• The most popular music style during the 1940s was swing, which prevailed during World War II. In the later periods of the 1940s, less swing was prominent and crooners like Frank Sinatra, along with genres such as bebop and the earliest traces of rock and roll, were the prevalent genre.
• Tango remained popular worldwide and several of the most famous tangos were composed in this decade, such as Malena, Garúa, Nada, Naranjo en flor, and many others.

Because fashion items and fabrics were rationed due to World War II, fashion became more utilitarian. Women's fashion started including suits, which were feminized with straight knee-length skirts and accessories. There were challenges imposed by shortages in rayon, nylon, wool, leather, rubber, metal (for snaps, buckles, and embellishments), and even the amount of fabric that could be used in any one garment.{{Cite web |last=Goles |first=Kelly |date=2023-01-19 |title=What Not to Wear: Clothing Rationing During World War II {{!}} In Custodia Legis |url=https://blogs.loc.gov/law/2023/01/what-not-to-wear-clothing-rationing-during-world-war-ii/ |access-date=2025-04-06 |website=The Library of Congress}} After the fall of France in 1940, Hollywood drove fashion in the United States almost entirely, with the exception of a few trends coming from wartorn London in 1944 and 1945, as America's own rationing hit full force. The idea of function seemed to overtake fashion, if only for a few short months until the end of the war. Fabrics shifted dramatically as rationing and wartime shortages controlled import items such as silk and furs.{{Cite web |title=How Clothes Rationing Affected Fashion In The Second World War |url=https://www.iwm.org.uk/history/how-clothes-rationing-affected-fashion-in-the-second-world-war |access-date=2025-04-06 |website=Imperial War Museums |language=en}} Floral prints dominated the early 1940s, with the mid-to-late 1940s also seeing what is sometimes referred to as "atomic prints" or geometric patterns and shapes. In response to the war effort, patriotic nautical themes and dark greens and khakis dominating the color palettes, as trousers and wedges slowly replaced the dresses and more traditional heels due to shortages in stockings and gasoline. The most common characteristics of this fashion were the straight skirt, pleats, front fullness, squared shoulders with v-necks or high necks, slim sleeves and the most favorited necklines were sailor, mandarin and scalloped.

During the 1940s, sporting events were disrupted and changed by the events that engaged and shaped the entire world. The 1940 and 1944 Olympic Games were cancelled because of World War II. During World War II in the United States Heavyweight Boxing Champion Joe Louis and numerous stars and performers from American baseball and other sports served in the armed forces until the end of the war. Among the many baseball players (including well known stars) who served during World War II were Moe Berg, Joe DiMaggio, Bob Feller, Hank Greenberg, Stan Musial (in 1945), Warren Spahn, and Ted Williams. They like many others sacrificed their personal and valuable career time for the benefit and well-being of the rest of society. The Summer Olympics were resumed in 1948 in London and the Winter games were held that year in St. Moritz, Switzerland.

In 1947, Wataru Misaka of the New York Knicks became the first person of color to play in modern professional basketball, just months after Jackie Robinson had broken the color barrier in Major League Baseball for the Brooklyn Dodgers.{{cite news|title=New York Times|date=22 November 2019|url=https://www.nytimes.com/2019/11/21/sports/basketball/wat-misaka-dead.html|access-date=November 26, 2019|last1=Goldstein|first1=Richard}}

During the early 1940s World War II had an enormous impact on Major League Baseball as many players including many of the most successful stars joined the war effort. After the war many players returned to their teams, while the major event of the second half of the 1940s was the 1945 signing of Jackie Robinson to a players contract by Branch Rickey the general manager of the Brooklyn Dodgers. Signing Robinson opened the door to the integration of Major League Baseball finally putting an end to the professional discrimination that had characterized the sport since the 19th century.

During the mid-1930s and throughout the years leading up to the 1940s Joe Louis was an enormously popular Heavyweight boxer. In 1936, he lost an important 12 round fight (his first loss) to the German boxer Max Schmeling and he vowed to meet Schmeling once again in the ring. Louis' comeback bout against Schmeling became an international symbol of the struggle between the US and democracy against Nazism and Fascism. When on June 22, 1938, Louis knocked Schmeling out in the first few seconds of the first round during their rematch at Yankee Stadium, his sensational comeback victory riveted the entire nation. Louis enlisted in the U.S. Army on January 10, 1942, in response to the Japanese attack on Pearl Harbor. Louis' cultural impact was felt well outside the ring. He is widely regarded as the first African American to achieve the status of a nationwide hero within the United States, and was also a focal point of anti-Nazi sentiment leading up to and during World War II.{{cite book |url=https://books.google.com/books?id=kC4qYeafQzMC&pg=PA64 |location=New York |title=Sports Matters: Race, Recreation, and Culture |editor=John Bloom |editor2=Michael Nevin Willard |year=2002 |publisher=New York University Press |isbn=978-0-8147-9882-9 |pages=46–47 |author1=Bloom, John |author2=Willard, Michael Nevin}}
