Life After Treaty:
After the treaty was signed the United States gained what is now southern U.S. Mexican citizens who lived in the territories ceded by the Treaty of Guadalupe Hidalgo to the U.S. These people were promised U.S. citizenship and their former lands by the United States. When citizens of the eastern U.S. traveled into the new territories (another effect), the Mexican peoples’ claims on the lands were ignored as the “easterners” stole those lands and settled down. Using the Treaty of Guadalupe Hidalgo as one of their key arguments, many of these Mexicans tried to regain their lost lands through lawsuits. They, however, were unsuccessful. After the treaty the U.S gained massive amounts of territory, which was the equivalent of 66% of the U.S. before the reception of the territory. One con to the treaty being signed was the aftermath of the war that led to the disruptions in Congress and the build up of hatred between the North and South for each had a specific stance when it came to the problem/practice of slavery. Many years later the problem is that too many illegal immigrants are crossing the boundaries set by the treaty which has cause many controversy. Many Mexican argue that those were their land first and that many Americans ancestors were immigrants where it was not required to fill out anything but to step foot on American soil.
