Itzamnaaj Bʼalam II was a Mayan king who ruled in Yaxchilan. Experts usually date his reign between the end of the 6th century and the beginning of the 7th century, around 599[1] or even until around 610.[2] Very little is known of him. He is also called Shield Jaguar by modern writers, based on the name glyph before the phonetic name was deciphered.
