Yaxchilan's lack of an inscribed history from 537 to 629 implies that it may have fallen under the dominion of a more powerful neighbour.
It may be that the lack of an inscribed history for this lengthy period indicates that Yaxchilan had fallen under the dominion of a more powerful neighbour, such as Piedras Negras, Palenque or Tonina, all of which were powerful polities in the Usumacinta region at this time. Little is known of the history of Yaxchilan from 537 to 629, although four kings are known to have reigned in this period.
