Yamanquex
Amanquex is named in records of Zacateco leaders active on the northern mining frontier during the Chichimeca War. The country around San Martín, Papantón and Sombrerete lay along routes carrying goods and travelers between the mines and central New Spain. Zacateco communities resisted the advance of Spanish settlements, and their attacks made the roads difficult to secure. The leader of Amanquex appears among several local chiefs whose followers took part in this prolonged struggle.
