Great Depression The Great Depression was a severe worldwide economic depression that took place mostly during the 1930s, originating in the United States. The timing of the Great Depression varied across nations; in most countries it started in 1929 and lasted until 1941. It was the longest, deepest, and most widespread depression of the 20th century. In the 21st century, the Great Depression is commonly used as an example of how far the world's economy can decline.
Great Depression in Chile The Great Depression that begun 1929 was felt strongly in Chile from 1930 to 1932. Saltpetre and copper exports collapsed. The World Economic Survey of the League of Nations declared Chile the worst affected nation by the depression. The crisis caused the authoritarian regime of Carlos Ibáñez del Campo to fall in July 1931 followed by a succession of short-lived governments until the election of Arturo Alessandri in December 1932. The economic crisis rose the levels of unemployment and caused a migration of unemployed saltpetre miners from the north to Santiago. Miners constituted around 6% of the active population but made up more than half of the unemployed during the crisis. Numerous soup kitchens sprang up in Santiago while homeless people begun to dwell in caves in the hills around Santiago. The state responded to the crisis by gradually raising tariffs, increasing internal demand and increasing control over the "flux and use" of foreign currency. Quotas and licences were established for imports and the gold convertibility was once again abolished in 1931.
