Kʼinich Janaab Pakal I, also known as Pacal or Pacal the Great, 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. Pakal reigned 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 longest of any residing monarch in the history of the Americas. During his reign, 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.

Copán is an archaeological site of the Maya civilization in the Copán Department of western Honduras, not far from the border with Guatemala. It is one of the most important sites of the Maya civilization, which was not excavated until the 19th century. The ruined citadel and imposing public squares reveal the three main stages of development before the city was abandoned in the early 10th century.
