The sharp increase in Mexican immigration in the early 20th century has several causes, mostly economic. Sugar consumption was on the rise nationally, and technological breakthroughs in the sugar beet industry allowed Midwestern farms to expand in attempt to meet that need. As they expanded, the need for labor increased. Sugar beet growing requires a significant amount of difficult manual labor, and immigration restrictions on Europeans during the time limited their availability to work in the United States. Additionally, Mexican labor was desired because of their strong work ethic and acceptance of lower wages. Consequently, Mexicans were recruited by the American Beet Sugar Company (American Crystal Sugar Company) from Mexico and the southwestern states to work in the north central part of the state, especially around Mason City. For many of the same reasons that Mexicans were recruited to work in the sugar beet industry, they were also recruited to work on the railroads in Iowa. Many of the Mexicans recruited to work on the railroads established communities at Fort Madison, Council Bluffs, Des Moines, and Davenport. Additionally, a significant revolution in Mexico in 1910 led more Mexicans to emigrate, and ultimately arrive in Iowa.
