Yikʼin Chan Kʼawiil[N 1] also known as Ruler B, Yaxkin Caan Chac and Sun Sky Rain, (before 734-c.746/766?

[N 2][2] Identified by Mayanist epigraphers as the 27th ruler in Tikal's dynastic succession,[3] Yikʼin Chan Kʼawiil was one of Tikal's most successful and expansionary rulers, consolidating the political gains won by his father, Jasaw Chan Kʼawiil I.

During his reign prolific building works were undertaken at Tikal, with a number of the site's significant still-standing structures commissioned or extended under his direction.

[2] Yikʼin Kʼawiil conquered Calakmul in 736 and two other Calakmul allies in 743 and 744: El Peru to the east and Naranjo to the west, destroying the noose of power that had previously dominated the area.

[citation needed] It is unknown exactly where his tomb lies, but strong archaeological parallels between Burial 116 (the resting place of his father) and Burial 196, located in the diminutive pyramid immediately south of Tikal Temple II and referred to as Structure 5D-73, suggest the latter may be the tomb of Yikʼin Chan Kawiil.
