What happened to many European immigrants who came to the United States

during the Great Depression?

On the Great Plains, environmental catastrophe deepened America's longstanding agricultural crisis and magnified the tragedy of the Depression. Beginning in 1932, severe droughts hit from Texas to the Dakotas and lasted until at least 1936. The droughts compounded years of agricultural mismanagement. To grow their crops, Plains farmers had plowed up natural ground cover that had taken ages to form over the surface of the dry Plains states. Relatively wet decades had protected them, but, during the early 1930s, without rain, the exposed fertile topsoil turned to dust, and without sod or windbreaks such as trees, rolling winds churned the dust into massive storms that blotted out the sky, choked settlers and livestock, and rained dirt not only across the region but as far east as Washington, D. C., New England, and ships on the Atlantic Ocean. The "Dust Bowl," as the region became known, exposed all-too-late the need for conservation. The region's farmers, already hit by years of foreclosures and declining commodity prices, were decimated. For many in Texas, Oklahoma, Kansas, and Arkansas who were "baked out, blown out, and broke," their only hope was to travel west to California, whose rains still brought bountiful harvests and-potentially-jobs for farmworkers. It was an exodus. Oklahoma lost 440,000 people, or a full 18.4 percent of its 1930 population, to out-migration.
