Sayollan

Sayollan was a polity centred on Sayula in the salt-lake country of southern Xalisco, in modern Jalisco. Its Nahuatl name meant the place where flies abound.

In 1480 the Purépecha invaded for the region's saltpeter, beginning the Saltpeter War. Cuantoma, lord of Sayula and Tapalpa and a tributary of Colima, was defeated at Acatlán but won at Zacoalco with troops led by Moz of Tepic. After Cuantoma died in 1502, Sayula became a Purépecha vassal lordship; in 1519 it passed into the orbit of Xalisco.
