His parents are not known. He was a successor of the king
Itzamnaaj Kʼawiil. The fact that Uchaʼan Kʼin Bʼalam followed Itzamnaaj Kʼawiil on the throne even though the latter probably had a son, can be explained in this way: the royal prince was too young to assume the rulership on his own, so there was a need for his regent. One depiction shows us Uchaʼan Kʼin Bʼalam presiding over a ritual featuring a young boy, presumably the prince and his successor
Kʼawiil Chan Kʼinich. Uchaʼan Kʼin Bʼalam is famous for capturing
Yichʼaak Bʼalam, king of
Seibal. He erected victory monuments at both Dos Pilas and
Aguateca. He died on May 28, 741. ==Marriage==
