King who broke Calakmul in 695 and raised Temple I over Tikal.
For 130 years Tikal lived under Calakmulʼs shadow after defeat in 562. Jasaw, son of Nuun Ujol Chaak, waited, rebuilt alliances, then struck on 5 Aug 695. Calakmulʼs king fell, its gods were bound and carried to Tikal. Tikal became again greatest city of the Peten (WHE, Tikal; Britannica).
Crowned 3 May 682 after Tikalʼs 130-year hiatus with no stelae. Resumed carving — a declaration that Mutal was a kingdom again. Married Lady Lahan Unen Moʼ to secure the east road.
Met Calakmul in Bajo El Laberinto and won utterly. Seized the Snake kingʼs palanquin and effigies. Altar 5 shows Jasaw with bound captives. Calakmul never fully recovered; Tikal raised Temple I to celebrate.
47 m pyramid with giant roof-comb jaguar. Burial 116 held jade mosaic, pearls, 90 vessels. Son Yikʼin completed it and was buried opposite in Temple II.
