Sosola
Sosola lies among the hills between the Mixteca Alta and the central valleys of Oaxaca. Its Mixtec communities retained their lands and local institutions through colonial rule. A dispute in 1775 between the people of San Juan Sosola and San Jerónimo Sosola drew on a land deed written in Mixtec, showing how Indigenous-language documents remained important in defending claims to fields and boundaries long after the Spanish conquest.
