The fact is Native America spands the continent from Alaska down to Mesoamerica. The word Mexican was originally Mexicano in Spanish. This was from the Aztec meaning half-breed or mixed blood. Mestiso is the word for half-breed in Spanish, from the Castillian. Chicano also comes from the Aztec Mexicano. When the Spaniards came to Native America, they carried their language with them. The culture that later became the Mexican culture was a product of intercultural marriages. The Spainiards intermixed with every nation of local natives – the Oaxaca, Yaqui, Navajo, Comanche, and many others such as the Aztec, Maya, Toltec and Olmec. The product of these mixes is the Mexican. Being Mexican is being par Spainiard and part Native. So a true Mexican will always be a mixed blood because that is what Mexican means. Tucson was still part of Mexico until 1914 , when it became part of he Gadsden Purchase. Look at Guatemala, Honduras, Columbia, the homelands of the indigenous populations. We didn’t draw the borders and stateliness, so the borders crossed us. The eagle of the North and the condor of the South. We will meet with our relatives because we are one, as the fingers of our hand.
