The Stock Market Crash of 1929 marked the beginning of the Great Depression. While this event caused unrest worldwide, discontent was particularly strong in Germany. The newly created Weimar Republic could not adequately address the rapidly deteriorating economic situation. This seeming incompetence led to more and more people voting for parties that wanted to destroy German democracy, resulting in Adolf Hitler becoming the Chancellor of Germany on January 30, 1933. The next half a decade saw Hitler remilitarize Germany, culminating in the invasion of Poland on September 1, 1939.
World War I, The Weimar Republic, And Hyperinflation

Thus, in July 1919, one American dollar was equivalent to 14 Reichsmarks (RMS). By July 1920, it was worth 39.5 RMS. Finally, by November 1923, an American dollar was worth 4.2 trillion RMS. This economic turmoil prompted widespread civil unrest, the most notable manifestation of which was the 1923 Nazi Beer Hall Putsch in Munich. However, following the introduction of a new currency called the Retenmark, and the Dawes Plan, a more manageable series of reparations payments, the economy began to stabilize in 1924.

The German Reaction

With memories of the end of World War One and hyperinflation still fresh, general anger toward the Weimar Republic also increased. Said discontent was not helped by the Grand Coalition, a group of parties from across the political spectrum that had ruled Germany for the past two years, collapsing in 1930. Right-leaning centrist chancellor Heinrich Brüning then took office. He mostly ruled by emergency decree, forcing through deeply unpopular budget cuts and austerity measures. These policies provoked further outrage, with more and more Germans wanting to completely upend the entire democratic system.
Hitler Comes To Power

This occurred because the non-Nazi conservative elites believed that they could control him, with Hitler's Vice-Chancellor Franz von Papen famously proclaiming that " in two months' time, we will have squeezed Hitler into a corner until he squeaks." However, on February 27, 1933, the Reichstag caught fire. The following day, Hitler issued the Reichstag Fire Decree, a law that suspended all civil liberties. On March 23, he then passed the Enabling Act, allowing him to push through laws without the approval of the Reichstag or the President. Finally, on May 2, the Nazis seized the trade unions. In about three months, Hitler had come to control most major institutions in German society.
Major Battles Of World War II (WW2)Rather than being mere military campaigns, the outcomes of these battles shaped the futures of Europe, Asia, and the entire world.
The Great Depression allowed for anti-democratic sentiments to flourish in Germany. The Nazis took advantage of these feelings, steadily gaining electoral support until Hitler was finally named Chancellor. Therefore, while a straight line cannot be drawn from the Great Depression to World War II, it certainly can be understood as a major contributing factor in the conflict's main aggressor coming to power.
