The Picuris Pueblo has a population of only 270 now, but at one time it was one of the two largest pueblos with over 3,000 Indians. European diseases and attacks from the Apache decreased the population dramatically over time. The Pueblo Revolt of 1680 did not fare well for the Indians in this community; however, the Picuris were considered fierce warriors and led much of the attack against the Spanish.  Picuris is located in an isolated valley in the Northern hills of New Mexico. They refer to themselves as the "People of the Hidden Valley".
