John Steinbeck wrote Of Mice and Men in 1936 about migrant farm workers in California during the Great Depression. Many farmers were driven off their land due to drought and economic hardship, traveling west to California in search of work. Steinbeck drew from his own experience working on a ranch to depict the difficult living and working conditions faced by migrants at that time, capturing their pursuit of the American Dream despite the challenges presented by the collapse of the economy.
