the great depression us history u.s. united states

The Great Depression was the worst economic slump ever in U.S. history, and one which spread to virtually all of the industrialized world. The depression began in late 1929 and lasted for about a decade. Many factors played a role in bringing about the depression; however, the main cause for the Great Depression was the combination of the greatly unequal distribution of wealth throughout the 1920's, and the extensive stock market speculation that took place during the latter part that same decade. The maldistribution of wealth in the 1920's existed on many levels. Money was distributed disparately between the rich and the middle-class, between industry and agriculture within the United States, and between the U.S. and Europe. This imbalance of wealth created an unstable economy.
