Okay so if we look at the European Colonization we see that it was the Spaniards who were the ones that explored the part of Mexico and New Mexico. And they did so for Christian Missions and to expand the faith to the New World. One of the Effects was bringing Catholicism to New Mexico and in fact wiping out the Aztec Indians by the conquistador a well known one would be, Hernan Cortes who was the leader. So the effects would be changing their religious beliefs and there way of culture by bringing horses and different ways of living. :) hope this helps :)
