				Already unstable, South America was hit hard by the Great Depression, with the global demand for the raw materials that formed the basis of the continent's economy collapsing. As the old establishment failed to handle the crisis, militarists and populists rose to power, taking inspiration from the apparent success of fascism in Europe. In late 1930, one such leader, Getúlio Vargas, seized control in Brazil, beginning an autocratic reign which would last until 1945.
