The Cordova rebellion occurred in 1838 by some groups including the Cherokee led by Vincent Cordova a Tejano from Nacogdoches, who were rebelling against the government of Texas.
It was later revealed that the Mexican government was secretly helping Vincent Cordova to raise an army for the rebellion. The purpose is to get recognition for tribal lands in Mexico.
