Carnivàle is an American television series set in the United States Dust Bowl during the Great Depression of the 1930s. The series, created by Daniel Knauf, ran for two seasons between 2003 and 2005. In tracing the lives of disparate groups of people in a traveling carnival, Knauf's story combined a bleak atmosphere with elements of the surreal in portraying struggles between good and evil and between free will and destiny. The show's mythology draws upon themes and motifs from traditional Christianity and gnosticism together with Masonic lore, particularly that of the Knights Templar order.

The Dust Bowl was the result of a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s. The phenomenon was caused by a combination of natural factors and human-made factors: a failure to apply dryland farming methods to prevent wind erosion, most notably the destruction of the natural topsoil by settlers in the region. The drought came in three waves: 1934, 1936, and 1939–1940, but some regions of the High Plains experienced drought conditions for as long as eight years.
