Changes

By the Treaty of Guadalupe Hidalgo the United States agreed to pay Mexico $15 million and to assume the unpaid claims by Americans against Mexico. In return, Mexico recognized the Rio Grande as the boundary of Texas and ceded New Mexico (including the present states of Arizona, New Mexico, Utah, and Nevada, a small corner of present-day Wyoming, and the western and southern portions of Colorado) and Upper California (the present state of California) to the United States. Mexico lost almost half of its land area to the United States by the terms of the treaty.
