Treaty of Guadalupe Hidalgo ends the Mexican–American War. Mexico loses 55 percent of its territory to the US, including California, Nevada and Utah in exchange for $15 million.

It followed the 1845 American annexation of Texas, which Mexico still considered its territory because it refused to recognize the Treaties of Velasco, signed by President Antonio López de Santa Anna after he was captured by the Texian Army during the 1836 Texas Revolution.
