USA HISTORY

Detailed explanation-1: -Under the terms of the treaty negotiated by Trist, Mexico ceded to the United States Upper California and New Mexico. This was known as the Mexican Cession and included present-day Arizona and New Mexico and parts of Utah, Nevada, and Colorado (see Article V of the treaty).

Detailed explanation-2: -With the annexation of more than 525, 000 square miles of land, the Treaty of Guadalupe Hidalgo extended the boundaries of the United States west to the Pacific Ocean. This agreement, along with the 1853 Gadsden Purchase, created the southern border of the present-day United States.

Detailed explanation-3: -The Gadsden Purchase, or Treaty, was an agreement between the United States and Mexico, finalized in 1854, in which the United States agreed to pay Mexico $10 million for a 29, 670 square mile portion of Mexico that later became part of Arizona and New Mexico.

Detailed explanation-4: -The treaty added an additional 525, 000 square miles to United States territory, including the land that makes up all or parts of present-day Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming. Mexico also gave up all claims to Texas and recognized the Rio Grande as America’s southern boundary.

Detailed explanation-5: -The United States wanted the Mexican Cession for the land. It was the largest land transfer since the Louisiana Purchase, which Americans had already largely occupied. In particular, the control of California was especially appealing and guaranteed American access to the Pacific Ocean.
