Chimalpahin Cuauhtlehuanitzin

Domingo Francisco de San Antón Muñón Chimalpahin Quauhtlehuanitzin (1579, Amecameca, Chalco—1660, Mexico City), usually referred to simply as Chimalpahin or Chimalpain, was a Nahua annalist from Chalco. His Nahuatl names (Nahuatl pronunciation: [tʃiːmaɬˈpaː.in kʷaːʍtɬeːwaˈnitsin]) mean "Runs Swiftly with a Shield" and "Rising Eagle", respectively, and he claimed descent from the lords of Tenango-Amecameca-Chalco.

He wrote on the history of Mexico and other neighboring nations in the Nahuatl and Spanish languages, but the majority of his works have not survived. The most important of his surviving works is the Relaciones or Anales. This Nahuatl work was compiled in the early seventeenth century, and is based on testimony from Indigenous persons. It covers the years 1589 through 1615, but also deals with events before the Conquest and supplies lists of Indigenous kings and lords and Spanish viceroys, archbishops of Mexico and inquisitors. Chimalpahin recorded the 1610 and 1614 visits of Japanese delegations to Mexico, led by Tanaka Shōsuke and Hasekura Tsunenaga, respectively.

He also wrote Diferentes historias originales (also known as Relaciones originales), a compilation of claims and proofs of nobility asserted by Indigenous leaders of Chalco-Amequemecan. It was written to serve as a judicial guide for the viceregal authorities for the granting of privileges and offices to members of the Indigenous nobility. There are eight of these relaciones. All contain ethnographic, social and chronologic information of great value to historians.
