 Texts record the arrival of a warrior named K'uk' Mo' Ajaw who was installed upon the throne of the city in AD 426 and given a new royal name, K'inich Yax K'uk' Mo' and the "ochk'in kaloomte" "Lord of the West" title used a generation earlier by Siyaj K'ak', a general from the great metropolis of Teotihuacan who had decisively intervened in the politics of the central Petén.K'inich Yax K'uk' Mo' was probably from Tikal and was likely to have been sponsored by Siyaj Chan K'awill II, the 16th ruler in the dynastic succession of Tikal.K'inich Yax K'uk' Mo' may have legitimized his claim to rulership by marrying into the old Copán royal family, evidenced from the remains of his presumed widow.
