B'alaj Chan K'awiil (Ruler 1) (c. 648–692+) was born on 15 October AD 625. He claimed to be a member of the Tikal royal line. On Dos Pilas Panel 6 he names a king of Tikal as his father. He probably saw himself as the legitimate heir to the Tikal throne and defected from Tikal in AD 648 to found Dos Pilas as a rival kingdom under the overlordship of Calakmul. B'alaj Chan K'awiil is known to have taken two wives, one of them from the nearby Petexbatún kingdom of Itzan. His father was K'inich Muwaan Jol II, who was either the 23rd or 24th ruler in Tikal's dynastic line. A daughter of B'alaj Chan K'awiil, Wak Chanil Ajaw, left Dos Pilas to found a dynasty at Naranjo.
