Yaxchilan

Yaxchilan () is an ancient Maya city located on the bank of the Usumacinta River in the state of Chiapas, Mexico. In the Late Classic Period Yaxchilan was one of the most powerful Maya states along the course of the Usumacinta River, with Piedras Negras as its major rival. Architectural styles in subordinate sites in the Usumacinta region demonstrate clear differences that mark a clear boundary between the two kingdoms.

Yaxchilan was a large center, important throughout the Classic era, and the dominant power of the Usumacinta River area. It dominated such smaller sites as Bonampak, and had a long rivalry with Piedras Negras and at least for a time with Tikal; it was a rival of Palenque, with which Yaxchilan warred in 654.
