The 1940s was the decade that started on January 1, 1940, and ended on December 31, 1949. This was the fifth decade of the 20th century.

The Second World War took place in the first half of the decade, which had a profound effect on most countries and people in Europe, Asia and elsewhere. The consequences of the war lingered well into the second half of the decade, with a war-weary Europe divided between the jostling spheres of influence of the West and the Soviet Union. To some degree internal and external tensions in the post-war era were managed by new institutions, including the United Nations, the welfare state and the Bretton Woods system, providing to the post–World War II boom, which lasted well into the 1970s. However the conditions of the post-war world encouraged decolonialization and emergence of new states and governments, with India, Pakistan, Israel, Vietnam and others declaring independence, rarely without bloodshed. The decade also witnessed the early beginnings of new technologies (including computers, nuclear power and jet propulsion), often first developed in tandem with the war effort, and later adapted and improved upon in the post-war era.

The Walt Disney Studios released the animated feature films Pinocchio (1940), Dumbo (1941), Fantasia (1941), and Bambi (1942).

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.

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.^[5][6][7] 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 Toshirō Mifune that lasted until 1965.

Music[link]

This section requires expansion.

• 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.

Fashion[link]

Even with the 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, the fashion industry's wheels kept chugging slowly along, producing what it could. 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 war torn London in 1944 and 1945, as America's own rationing hit full force, and 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. Floral prints seem to dominate the early 1940s, with the mid-to-late 1940s also seeing what is sometimes referred to as "atomic prints" or geometric patterns and shapes. The color of fashion seemed to even go to war, with patriotic nautical themes and dark greens and khakis dominating the color palates, as trousers and wedges slowly replaced the dresses and more traditional heels due to shortages in stockings and gasoline.
