Early Mid 20th Century


In this period, it became increasingly apparent that the "War to end all wars" had not done so. The new transportation and communication technologies that were being developed were given military applications. In most major nations, Socialist and fascist idealogies were used to address the effects of a major economic depression and embodied in belligerent militarized secular dictatorships. The period closed with the beginnings of a second and more extensive World War, which included Asia as well as Europe.

Early 1920s

With Lenin's leadership, the Communist took control of the Russian Empire, renaming it the Union of Soviet Socialist Republics, and adapted Marxism to be the state-approved ideology.

Late 1920s

Speculation in stocks in the US created a financial bubble. When the stock market crashed in 1929, it initiated a worldwide economic depression.

Early 1930s

Japan occupied Manchuria and set up a puppet state in China.
