California in the 1930s had an area of 424,000 square kilometers along the western coast of the US bordering Mexico. The state was prone to earthquakes and faced economic hardship during the Great Depression, with many farmers losing their land and migrating as unemployed "tramps" or "Okies" seeking work. Popular music genres included boogie and blues, performed by notable artists like Billie Holiday, Louis Armstrong, and Bing Crosby.
