The state is named after its capital, Tlaxcala, which was also the name of the Pre-Columbian city and culture. The Tlaxcalans allied themselves with the Spanish to defeat the Aztecs, with concessions from the Spanish that allowed the territory to remain mostly intact throughout 300 years of colonial period. After Mexican Independence, Tlaxcala was declared a federal territory, until 1857 when it was admitted as a state of the federation.
