Kʼinich Janaab Pakal I, also known as Pacal, Pacal the Great, 8 Ahau and Sun Shield, was ajaw of the Maya city-state of Palenque in the Late Classic period of pre-Columbian Mesoamerican chronology. He acceded to the throne in July 615 and ruled until his death. During a reign of 68 years—the fifth-longest verified regnal period of any sovereign monarch in history, the longest in world history for more than a millennium, and still the second longest in the history of the Americas—Pakal was responsible for the construction or extension of some of Palenque's most notable surviving inscriptions and monumental architecture. Pakal is perhaps best-known in popular culture for his depiction on the carved lid of his sarcophagus, which has become the subject of pseudoarchaeological speculations.
