The Great Depression was a worldwide economic depression which took place in in the end of the 1920s and during 1930s. It started in the United States after a major fall in stock prices and then spread to the rest of the world. However, Depression did not have an impact on the Soviet Union, because it did not participate in the world market. The depression lasted until the end of the World War II.
In Germany, or Weimar Republic, the economic crash had huge consequences for the economy of the state, because Germany were largely dependent on the US investors and their loans. Being unable to pay war reparations, the crsis had spread to other countries as well, mainly France, which was dependent on the steady reparations. WIth the overturn of powers in the elections, Germany started to fight the depression by increasing public spending, mainly in the field of military equipment.
Meanwhile, in the US, for the first time in its history, the federal government started to involve itself into stimulating the economy, by increasing defense spending. It also made effort to increase employment and regulate banking with its monetary reforms.
