The son of a Spanish conquistador and an Indian woman, Diego Muñoz Camargo was educated as a Spaniard, but was also steeped in indigenous culture through his Indian family connections.  An historian and interpreter, he was also a government official and landholder in the Tlaxcala region of Mexico.  In this manuscript, written in the late sixteenth century, Muñoz Camargo covers the history of Tlaxcala, the events of the conquest (and the Tlaxcalan support of Cortés), as well as the natural and geographical background of the area.
