Why Spanish? – Spain conquered what is now Mexico and the Southwestern United States (the Aztec Empire and adjoining nations) in the 16th Century. "During the colonial period, which lasted from 1521 to 1810, Mexico was known as “Nueva España” or “New Spain”, whose territories included today’s Mexico, the Spanish Caribbean islands, Central America as far south as Costa Rica, an area comprising today’s southwestern United States, and the Philippine Islands." http://en.wikipedia.org/wiki/Mexico
