Chichimeca War

The Chichimeca War (1550–1600) was a military conflict between the Spanish Empire and the Chichimeca Confederation established in the territories today known as the Central Mexican Plateau (called La Gran Chichimeca by the conquistadores). The epicenter of the hostilities was the region now called the Bajío. The Chichimeca War is recorded as both the longest and most expensive military campaign confronting the Spanish Empire and indigenous people in Aridoamerica. The 50-year conflict was settled through several peace treaties with the Spaniards which led to the pacification and, ultimately, the integration of the native populations into the New Spain society.
