In page Quetzaltenango:

"

In pre-Columbian times, Quetzaltenango was a city of the Mam Maya people called Xelajú, although by the time of the Spanish Conquest it had become part of the K'iche' Kingdom of Q'umarkaj[citation needed]. The name may be derived from xe laju' noj meaning "under ten mountains". The city was said to have already been over 300 years old when the Spanish first arrived. With the help of his allies, Conquistador Pedro de Alvarado defeated and killed the Maya ruler Tecún Umán here[citation needed].
