Biography
Before advances in the decipherment of the Maya script revealed this reading of his name, this ruler was also known to researchers as Tikal Ruler A, Jasaw Chan Kʼawiil or by the nickname Ah Cacao.

One of the most celebrated of Tikal's rulers, Jasaw Chan Kʼawiil's reign came at the end of a 130-year-long hiatus in Tikal's historical record, and his defeat of the rival Maya city of Calakmul in 695 is seen to represent a resurgence in the strength and influence of Tikal.

Two structures at Tikal in particular are associated with Jasaw Chan Kʼawiil. Tikal Temple I is a classically Petén-styled stepped pyramid structure which served as this ruler's tomb, although it is unclear whether it was built for this specific purpose. Tikal Temple II served as the tomb for his wife, Lady Lahan Unen Moʼ (died c.704). His successor was his son Yikʼin Chan Kʼawiil.
