Powerful Nations

At the beginning of the period, Britain was the world's most powerful nation^[2]; having acted as the world's policeman for the past century. Fascism, a movement which grew out of post-war angst and which accelerated during the Great Depression of the 1930s, gained momentum in Italy, Germany and Spain in the 1920s and 1930s, culminating in World War II (1939–1945), sparked by Nazi Germany's aggressive expansion at the expense of its neighbors. Meanwhile, Japan had rapidly transformed itself into a technologically advanced industrial power. Its military expansion into eastern Asia and the Pacific Ocean culminated in a surprise attack on the United States, bringing it into World War II. After having had several years of dramatic military success, Germany was defeated in 1945, having been repelled and invaded by the Soviet Union from the east and invaded from the west by the United States, the United Kingdom, Canada, and Free France. The war ended with the dropping of two atomic bombs on Japan. Japan later became a U.S. ally with a powerful economy based on consumer goods and trade. Germany was divided between the western powers and the Soviet Union; all areas recaptured by the Soviet Union (East Germany and eastward) were essentially transitioned into Soviet puppet states under communist rule. Meanwhile, western Europe was influenced by the American Marshall Plan and made a quick economic recovery, becoming major allies of the United States under capitalist economies and relatively democratic governments.

XX Century History (Summary)

The early arms races of the 20th century escalated into a war which involved many powerful nations: World War I (1914–1918). Technological advancements changed the way war was fought, as new inventions such as machine guns, tanks, chemical weapons, grenades, and military aircraft modified tactics and strategy. After more than four years of trench warfare in western Europe, and 20 million dead, those powers who had formed the Triple Entente (France, Britain, and Russia, later replaced by the United States and joined by Italy) emerged victorious over the Triple Alliance (Germany, Austria-Hungary, and the Ottoman Empire). In addition to annexing much of the colonial possessions of the vanquished states, the Triple Entente exacted punitive restitution payments from their former foes, plunging Germany in particular into economic depression. The Tsarist regime of His Imperial Majesty Nicholas II was overthrown during the conflict and Russia was transitioned into the first ever communist state, and the Austro-Hungarian and Ottoman empires were dismantled at the war's conclusion.
