Human sacrifice in Maya culture in the context of Relación de las cosas de Yucatán

Diego de Landa Calderón, O.F.M. (12 November 1524 – 29 April 1579) was a Spanish Franciscan bishop of the Roman Catholic Archdiocese of Yucatán. He led a campaign against idolatry and human sacrifice. In doing so, he burned Maya manuscripts (codices) which contained knowledge of Maya religion and civilization, and the history of the American continent. Ironically, however, his work in documenting and researching the Maya was indispensable in achieving the current understanding of their culture, to the degree that Mayanist William Gates asserted that "ninety-nine percent of what we today know of the Mayas, we know as the result either of what Landa has told us in the pages that follow, or have learned in the use and study of what he told". He also described that "it is an equally safe statement that... he burned ninety-nine times as much knowledge of Maya history and sciences as he has given us".

Sacrifice was a religious activity in Maya culture, involving the killing of humans or animals, or bloodletting by members of the community, in rituals superintended by priests. Sacrifice has been a feature of almost all pre-modern societies at some stage of their development and for broadly the same reason: to propitiate or fulfill a perceived obligation towards the gods.

Human sacrifice was a common practice in many parts of Mesoamerica. The rite was not new to the Aztecs when they arrived at the Valley of Mexico, nor was it something unique to pre-Columbian Mexico. Other Mesoamerican cultures, such as the Purépechas and Toltecs, and the Maya performed sacrifices as well, and from archaeological evidence, it probably existed since the time of the Olmecs (1200–400 BC), and perhaps even throughout the early farming cultures of the region. However, the extent of human sacrifice is unknown among several Mesoamerican civilizations. What distinguished Aztec practice from Maya human sacrifice was the way in which it was embedded in everyday life.

Around 1521, when the Aztec capital of Tenochtitlan fell to Hernán Cortés's troops, Cortés and other European explorers and conquistadores made observations of and wrote reports about the practice of human sacrifice. Bernal Díaz del Castillo, who participated in the Cortés expedition, made frequent mention of human sacrifice in his memoir True History of the Conquest of New Spain. There are a number of second-hand accounts of human sacrifices written by Spanish friars that relate to the testimonies of native eyewitnesses. The literary accounts have been supported by archeological research.
