paragraph_text: The Mexican Cession is the region in the modern - day southwestern United States that Mexico ceded to the U.S. in the Treaty of Guadalupe Hidalgo in 1848. This region had not been part of the areas east of the Rio Grande which 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. The Mexican Cession (529,000 sq. miles) was the third largest acquisition of territory in US history.

paragraph_text: In 1845, the Republic of Texas was annexed to the United States of America, becoming the 28th U.S. state.

When the war concluded, Mexico relinquished its claim on Texas, as well as other regions in what is now the southwestern United States. Texas' annexation as a state that tolerated slavery had caused tension in the United States among slave states and those that did not allow slavery. The tension was partially defused with the Compromise of 1850, in which Texas ceded some of its territory to the federal government to become non-slave - owning areas but gained El Paso.

paragraph_text: In 1949, the Territory and the Territory of New Guinea were established in an administrative union by the name of the Territory of Papua and New Guinea.

Polk was elected the United States president after promising to annex Texas. Before he assumed office, the outgoing president, John Tyler, entered negotiations with Texas. On February 26, 1845, six days before Polk took office, the U.S. Congress approved the annexation. The Texas legislature approved annexation in July 1845 and constructed a state constitution. In October, Texas residents approved the annexation and the new constitution, and Texas was officially inducted into the United States on December 29, 1845.

paragraph_text: Francisco Garcés was the first European in the area. Nevada was annexed as a part of the Spanish Empire in the northwestern territory of New Spain. Administratively, the area of Nevada was part of the Commandancy General of the Provincias Internas in the Viceroyalty of New Spain. Nevada became a part of Alta California (Upper California) province in 1804 when the Californias were split. With the Mexican War of Independence won in 1821, the province of Alta California became a territory - not a state - of Mexico, due to the small population. In later years, a desire for increased autonomy led to several attempts by the Alta Californians to gain independence from Mexico. Jedediah Smith entered the Las Vegas Valley in 1827, and Peter Skene Ogden traveled the Humboldt River in 1828. As a result of the Mexican -- American War and the Treaty of Guadalupe - Hidalgo, Mexico permanently lost Alta California in 1848. The new areas acquired by the United States continued to be administered as territories. As part of the Mexican Cession (1848) and the subsequent California Gold Rush that used Emigrant Trails through the area, the state's area evolved first as part of the Utah Territory, then the Nevada Territory (March 2, 1861; named for the Sierra Nevada). The capitol is Carson City

The Foraker Act of 1900, which established a civil government, and the Jones Act of 1917, which made Puerto Ricans U.S. citizens, paved the way for the drafting of Puerto Rico's Constitution and its approval by Congress and Puerto Rican voters in 1952.
