Much of the Early Classic history of the city still awaits the archaeologist's trowel. However, from the extent of the surveyed site and the reference to Early Classic rulers in the inscriptional record of the Late Classic, it is clear Palenque's history is much longer than we currently know. The fact that early ajaw (king or lord) and mythological beings used a variety of emblem glyphs in their titles indeed suggests a complex early history. For instance, K'uk' B'ahlam, the supposed founder of the Palenque dynasty, is called a Toktan Ajaw in the text of the Temple of the Foliated Cross.
The famous structures that we know today probably represent a rebuilding effort in response to the attacks by the city of Calakmul and its client states in 599 and 611. One of the main figures responsible for rebuilding Palenque and for a renaissance in the city's art and architecture is also one of the best-known Maya Ajaw, K'inich Janaab' Pakal (Pacal the Great), who ruled from 603 to 683. He is best known through his funerary monument, dubbed the Temple of Inscriptions after the lengthy text preserved in the temple's superstructure. At the time Alberto Ruz Lhuillier excavated Pakal's tomb it was the richest and best preserved of any scientifically excavated burial then known from the ancient Americas. It held this position until the discovery of the rich Moche burials at Sipan, Peru and the recent discoveries at Copan and Calakmul.
Beside the attention that K'inich Janaab' Pakal's tomb brought to Palenque, the city is historically significant for its extensive hieroglyphic corpus composed during the reigns of Janaab' Pakal his son K'inich Kan B'ahlam and his grandson K'inich Akal Mo' Naab', and for being the location where Heinrich Berlin and later Linda Schele and Peter Mathews outlined the first dynastic list for any Maya city. The work of Tatiana Proskouriakoff as well as that of Berlin, Schele, Mathews, and others initiated the intense historical investigations
