As has been the case from the dawn of writing, U.S. Latino/a authors often express religious themes and attitudes in their literature. Although some scholars begin the history of U.S. Latino/a literature with the arrival of the Spaniards, we draw some very clear boundaries as follows: 1848 for Mexican American literature; 1898 for Puerto Rican literature; 1959 for Cuban American literature; and later for other groups. Overall, U.S. Latino/ a literature reflects a triadic interaction among indigenous, Christian, and African religious traditions. The Christian tradition has been predominantly Catholic, with Protestant writers becoming a more recent phenomenon.
