Uaxaclajuun Ub'aah K'awiil, Mayan ruler (ajaw)

Uaxaclajuun Ubʼaah Kʼawiil, was the 13th ajaw or ruler of the powerful Maya polity associated with the site of Copán in modern Honduras. He ruled from January 2, 695, to May 3, 738.

Ajaw or Ahau ('Lord') is a pre-Columbian Maya political title attested from epigraphic inscriptions. It is also the name of the 20th day of the tzolkʼin, the Maya divinatory calendar, on which a ruler's kʼatun-ending rituals would fall.
