Coinan

Coinan was a hereditary monarchy of the Coca on the north-eastern shore of Lake Chapala in present-day Mexico. Its capital was Tototlan, and chiefdoms including Atotonilco and Ocotlan paid tribute. Its kings fought the neighbouring Purépecha Empire.

Coinan stayed out of the Saltpeter War, but in 1541 joined the Mixtón War alongside the Caxcanes and Tecuexe, fielding perhaps fourteen thousand rebels. After the Caxcanes were defeated, the Coca also surrendered.
