The Treaty of Guaalupe Hidalgo (Tratado de Guadalupe Hidalgo in Spanish) is the peace treaty, largely dictated by the United States to the interim government of a militarily occupied Mexico, that ended the Mexican-American War (1846–1848). The treaty provided for the Mexican Cession, in which Mexico ceded 1.36 million km² (525,000 square miles) (55% of its pre-war territory) to the United States in exchange for US$15 million (equivalent to $313 million in 2006 dollars) and the ensured safety of pre-existing property rights of Mexican citizens in the transferred territories, the latter of which the United States in a significant number of cases failed to honor. The United States also agreed to take over $3.25 million ($68 million in 2006 dollars) in debts Mexico owed to American citizens.
