709 CE
Itzamnaaj B'alam has a second wife named Lady Eveningstar of Calakmul with whom he has a son named Yaxun Bʻalam.
One of Itzamnaaj B'alam's greatest accomplishments is the construction of what is now called Temple 23.
At Temple 23, Lady Xoc is shown performing a bloodletting ritual for three different occasions: Itz'amnáj B'alam's accession to the throne, the birth of Yaxun Bʻalam, and the dedication of Temple 23.
He chose Yaxun Bʻalam to be his successor despite the fact that Lady Xoc, his other wife, had a strategically important bloodline.
