Itzamnaaj K'awiil (Ruler 2) (698–726), another son of B'alaj Chan Kawiil, was born in AD 673, probably in Calakmul during his family's exile after Dos Pilas was defeated by Tikal. His birth abroad seems to have been cause for embarrassment, with discrepancies in the calendar dates recorded on monuments likely to be the result of attempts to show that he was born in Dos Pilas itself. He reigned for 28 years. He died on October 726. A stela erected by his successor records that he was buried four days later, at night and within Dos Pilas. A tomb believed to be that of this king was found under Structure L5-1 in the site core.
