Biography
Her father was Janahb Pakal and her mother was Yohl Ikʼnal or unknown. As Janaab Pakal seems to have had no male heirs, she ascended to the throne on 19 October 612, a few months after her father's death. After his maturity, her son Kʼinich Janaab Pakal I succeeded her as ruler on 9.9.2.4.8 5 Lamat 1 Mol. She seems to have continued to wield considerable influence over Palenque in the early decades of her son's reign. For example, Sak Kʼukʼ is recorded on Pakal's sarcophagus lid as the ruler who celebrated the sealing of the Kʼatun on 9.10.0.0.0 (25 January 633 AD). She was probably mother of Ajen Yohl Mat.
