It is not known what the final fate of the king was, and it is presumed that he was executed in Toniná. For 10 years there was no king. Finally, Kʼinich Ahkal Moʼ Nab' III was crowned in 722. Although the new king belonged to the royalty, there is no evidence that he was the direct inheritor of Kʼinich Kʼan Joy Chitam II. It is believed, therefore, that this coronation was a break in the dynastic line, and probably Kʼinich Ahkal Nab' arrived to power after years of maneuvering and forging political alliances. This king, his son, and grandson governed until the end of the 8th century. Little is known about this period, except that, among other events, the war with Toniná continued, where there are hieroglyphics that record a new defeat of Palenque.
