What happened
Later Tikal inscriptions, including the long dynastic list on Stela 31, name Yax Ehb Xook as the founder of the royal line that Maya epigraphers today call the Yax Mutal dynasty, beginning around 90 CE. Over the following nearly 800 years, Tikal's king list would run to roughly 33 rulers, all tracing their legitimacy back to this founding figure the way later Copan kings traced theirs to Yax K'uk' Mo'. Later rulers deliberately invoked Yax Ehb Xook by name in their own accession texts and dedicated monuments to him retroactively, which is standard practice across Classic Maya dynasties: a founder is named and commemorated generations after his actual reign to anchor a dynasty's claim to rule.
Why it matters
Establishing a named founding ruler gave Tikal's kings a genealogical claim to authority that could be cited on monuments for centuries, the same legitimizing function that Yax K'uk' Mo' would later serve for Copan. Tikal's dynasty founded here would go on to become one of the two superpowers of the Classic Maya world, locked for centuries in rivalry with Calakmul.
How we know
The dynastic sequence and founder's name come from retrospective king lists carved on later Tikal monuments, particularly Stela 31, cross-checked against burial and architectural sequences in the North Acropolis excavated by the University of Pennsylvania's Tikal Project.
