World War 2 Timeline

An illustrated timeline of key events during World War 2 including pre-war events cited as its causes.

Before the official beginning of WW II, a number of countries began to act in an aggressive and warlike manner. Adolf Hitler opened the first concentration camps as early as 1933 and became the “Fuhrer” or sole dictator of in 1934. Mussolini rose to power in 1935 and became the dictator in Italy. Both Mussolini and Hitler quickly began to increase their reach by seizing other smaller countries. Meanwhile China and were at war in Asia. Japan then signed an agreement with Germany, which added Britain and Franch to their list of enemies. As you review the causes of World War 2, some of the events and comments appear random, but they have a cumulative effect much like one domino systematically causing the others to fall.
