Ahkal Mo' Nahb I

Ahkal Mo' Nahb I, also known as Chaacal and Akul Anab I, (July 5, 465 – November 29, 524), was an ajaw of the Maya city of Palenque. He ruled from June 5, 501 AD to his death.

Ahkal Mo' Nahb I is the earliest recorded ruler of Palenque whose exact dates of birth, accession and death have been verified. He was possibly the younger brother of his immediate predecessor, B'utz Aj Sak Chiik. For unknown reasons Ahkal Mo' Nahb' is mentioned several times in official narratives left by Pacal the Great, who ruled Palenque a century later. It is believed Pacal considered Ahkal Mo' Naab' I a particularly important historical figure or his ancestor.
