Chan Chak Kʼakʼnal Ajaw

Kʼahkʼ Pulaj Chan Chaahk, also known as Lord Chac before the decipherment of his corresponding name glyphs, is currently the only archaeologically identified ruler of the pre-Columbian Maya polity at Uxmal, who ruled in the early 10th century.

Only a handful of details are known from this king, as hieroglyphic inscriptions, while very prominent in the Southern Maya Lowlands, are scarce in the north. What is known is that Lord Chac acceded to the throne somewhere at the end of the 9th century. During his rule, between 890–910 AD, some of the largest and most impressive buildings in Uxmal, such as the so-called Nunnery Quadrangle and the Governor's Palace, were built. An inscription at a large ballcourt in Uxmal, for playing the Mesoamerican ballgame, informs us it was dedicated in 901 during the reign of this king.
