The Seville Cancionero is a manuscript collection of songs from late fiftennth-century Spain and is preserved today in the Biblioteca Colombina of Seville with the number 7-1-28. This dissertation describes the document and provides commentary and transcriptions of the Seville Cancionero.

The focus of this thesis is the relationship between immigration historiography and the history of Basque migration to the United States. The depictions of immigration presented by historians Oscar Handlin, Marcus Lee Hansen, and John Higham have been influential in immigration historiography and are presented in the first chapter. The second chapter contains a description of Old World Basque culture and the third chapter presents a brief history of Basque migration to the United States. The fourth chapter discusses to what extent the immigration theories presented in chapter one match the Basque experience in the New World. The concluding chapter contains some observations on the nature of immigration historiography, on the Basques, and on new directions for research.
