The Treaty of Guadalupe Hidalgo, officially the Treaty of Peace, Friendship, Limits, and Settlement between the United States of America and the Mexican Republic, is the peace treaty that was signed on 2 February 1848, in the Villa de Guadalupe Hidalgo between the United States and Mexico that ended the Mexican–American War (1846–1848). The treaty was ratified by the United States on 10 March and by Mexico on 19 May. The ratifications were exchanged on 30 May, and the treaty was proclaimed on 4 July 1848.
The Territory of New Mexico was an organized incorporated territory of the United States from September 9, 1850, until January 6, 1912. It was created from the U.S. provisional government of New Mexico, as a result of Nuevo México becoming part of the American frontier after the Treaty of Guadalupe Hidalgo. It existed with varying boundaries until the territory was admitted to the Union as the U.S. state of New Mexico. This jurisdiction was an organized, incorporated territory of the US for nearly 62 years, the longest period of any territory in the contiguous United States.
The Mexican Cession is the region in the modern-day southwestern United States that Mexico ceded to the United States in the Treaty of Guadalupe Hidalgo in 1848 after the Mexican–American War. This region had not been part of the areas east of the Rio Grande that had been claimed by the Republic of Texas, though the Texas annexation resolution two years earlier had not specified the southern and western boundary of the new state of Texas. At roughly 529,000 square miles (1,370,000 km2), the Mexican Cession was the third-largest acquisition of territory in U.S. history, surpassed only by the 827,000-square-mile (2,140,000 km2) Louisiana Purchase and the 586,000-square-mile (1,520,000 km2) Alaska Purchase.
The Territory of Utah was an organized incorporated territory of the United States that existed from September 9, 1850, until January 4, 1896, when the final extent of the territory was admitted to the Union as the State of Utah, the 45th state. At its creation, the Territory of Utah included all of the present-day State of Utah, most of the present-day state of Nevada, much of present-day western Colorado, and the extreme southwest corner of present-day Wyoming.
The District of Louisiana, or Louisiana District, was an official and temporary United States government designation for the portion of the Louisiana Purchase that had not been organized into the Territory of Orleans or "Orleans Territory". The district officially existed from March 10, 1804, until July 4, 1805, when it was incorporated as the Louisiana Territory.
The territory of the United States and its overseas possessions has evolved over time, from the colonial era to the present day. It includes formally organized territories, proposed and failed states, unrecognized breakaway states, international and interstate purchases, cessions, and land grants, and historical military departments and administrative districts. The last section lists informal regions from American vernacular geography known by popular nicknames and linked by geographical, cultural, or economic similarities, some of which are still in use today.
The United States Court of Private Land Claims (1891–1904) was an ad-hoc court created to decide land claims guaranteed by the Treaty of Guadalupe Hidalgo, in the territories of New Mexico, Arizona, and Utah, and in the states of Nevada, Colorado, and Wyoming.

The 1763 Treaty of Paris ended the major war known by Americans as the French and Indian War and by Canadians as the Seven Years' War / Guerre de Sept Ans, or by French-Canadians, La Guerre de la Conquête. It was signed by Great Britain, France and Spain, with Portugal in agreement. Preferring to keep Guadeloupe, France gave up Canada and all of its claims to territory east of the Mississippi River to Britain. With France out of North America this dramatically changed the European political scene on the continent.
