I've been hearing weird things lately from the media that the brutal, cruel United States is actually "occupying" Mexican territory, or what used to be Mexican territory. They claim that all of California, Nevada, New Mexico, Texas, Arizona, Utah, and parts of Colorado originally belonged to Mexico and were stolen by the US and now occupied.
Cortez conquered present day Mexico in 1519 and ruled much of Mexico as well as the disputed land in the US for 300 years. This is why Mexicans speak Spanish. This entire area was called the Vice royalty of New Spain.
Mexicans fought and won their independence from Spain in 1821. However skirmishes between Americans living in present day US and the new Mexicans increased until in 1836, Texas declared it's independence from Mexico. This means that Texas was only considered part of Mexico for 15 years. Before that, it had been ruled by Spain for 300 years.
When in 1845, Texas became part of the United States, our army sent soldiers to patrol the border. Eleven of those men were murdered, prompting President Polk to declare war on Mexico. Over a year later, we had defeated Mexico and taken back all the territories that are now considered part of the United States.
The treaty of Guadeloupe signed in 1848 called for these provisions
US would withdraw from Mexico, including Mexico city
US would get Southwestern US, including Texas, California, Arizona, New Mexico, Utah, Colorado
In addition, even though we WON the war, we agreed to buy this land from Mexico for $15 Million. We are not occupying Mexican land. We won it in war and then paid for it.
Oddly, this seems quite familiar to another country struggling with accusations of "occupying" territory they also won in war. Israel.
