Yax Mayuy Chan Chaak [jaʃ majuj tʃan tʃaːk] (died 744?)
He was the king after K'ak' Tiliw Chan Chaak, who was possibly his older brother or his father.
[2] He played a role in a successful military conquest of the Komkom people in 726 CE, when he was a young man or teenager, according to Stela 18.
Because of the scarcity of monuments from his administration, his rule is considered to take place during the "Second Hiatus Period" at Naranjo.
He was possibly executed on February 4, 744 CE, the date of the stela's erection, or shortly after.
