paragraph_text: The 1848 Treaty of Guadalupe Hidalgo, forced onto the remnant Mexican government, ended the war and specified its major consequence, the Mexican Cession of the northern territories of Alta California and Santa Fe de Nuevo México to the United States. The U.S. agreed to pay $15 million compensation for the physical damage of the war. In addition, the United States assumed $3.25 million of debt already owed earlier by the Mexican government to U.S. citizens. Mexico acknowledged the loss of their province, later the Republic of Texas (and now the State of Texas), and thereafter cited and acknowledged the Rio Grande as its future northern national border with the United States. Mexico had lost over one - third of its original territory from its 1821 independence.

paragraph_text: Cuba, like many Spanish territories, wanted to break free from Spain. A pro-independence movement in Cuba was supported by the U.S., and Cuban guerrilla leaders wanted annexation to the United States, but Cuban revolutionary leader José Martí called for Cuban nationhood. When the U.S. battleship Maine sank in Havana Harbor, the U.S. blamed Spain and the Spanish–American War broke out in 1898. After the U.S. won, Spain relinquished claim of sovereignty over territories, including Cuba. The U.S. administered Cuba as a protectorate until 1902. Several decades later in 1959, the corrupt Cuban government of U.S.-backed Fulgencio Batista was overthrown by Fidel Castro. Castro installed a Marxist–Leninist government allied with the Soviet Union, which has been in power ever since.

paragraph_text: In 1898, during the Spanish -- American War, Puerto Rico was invaded and subsequently became a possession of the United States. The first years of the 20th century were marked by the struggle to obtain greater democratic rights from the United States. 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. However, the political status of Puerto Rico, a Commonwealth controlled by the United States, remains an anomaly.

paragraph_text: After the Spanish -- American War, Spain and the United States signed the Treaty of Paris (1898), by which Spain ceded Puerto Rico, the Philippines, and Guam to the United States for the sum of $20 million. Cuba gained formal independence from the U.S. on May 20, 1902, as the Republic of Cuba. Under Cuba's new constitution, the U.S. retained the right to intervene in Cuban affairs and to supervise its finances and foreign relations. Under the Platt Amendment, the U.S. leased the Guantánamo Bay naval base from Cuba.

paragraph_text: The capital city, Washington, District of Columbia, is a federal district located on land donated by the state of Maryland. (Virginia had also donated land, but it was returned in 1849.) The United States also has overseas territories with varying levels of independence and organization: in the Caribbean the territories of Puerto Rico and the U.S. Virgin Islands, and in the Pacific the inhabited territories of Guam, American Samoa, and the Northern Mariana Islands, along with a number of uninhabited island territories.

paragraph_text: The Mexican War of Independence (Spanish: Guerra de Independencia de México) was an armed conflict, and the culmination of a political and social process which ended the rule of Spain in 1821 in the territory of New Spain. The war had its antecedent in Napoleon's French invasion of Spain in 1808; it extended from the Grito de Dolores by Father Miguel Hidalgo y Costilla on September 16, 1810, to the entrance of the Army of the Three Guarantees led by Agustín de Iturbide to Mexico City on September 27, 1821. September 16 is celebrated as Mexican Independence Day.

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

paragraph_text: The United States eventually incorporated the Northern Line into its territories and did the same with the Phoenix Islands which lie between Kiribati and the Line Islands including Howland, Jarvis, and Baker islands, thus, bringing about a territorial dispute. This was eventually resolved and they became part of Kiribati as part of the Treaty of Tarawa. This was signed shortly after independence and ratified in 1983, the United States relinquishing all claims to the sparsely inhabited Phoenix Islands and those of the Line Islands that are part of Kiribati territory.

paragraph_text: Colorado Territory was officially organized by Act of Congress on February 28, 1861, out of lands previously part of the Kansas, Nebraska, Utah, and New Mexico territories. Technically the territory was open to slavery under the Dred Scott Decision of 1857, but the question was rendered moot by the impending American Civil War and the majority pro-Union sentiment in the territory. The name "Colorado" was chosen for the territory. It had been previously suggested in 1850 by Senator Henry S. Foote as a name for a state to have been created out of present-day California south of 35° 45'. To the dismay of Denverites, the town of Colorado City was designated the first territorial capital, quickly succeeded by Golden. Denver eventually became the temporary territorial capital, but was not designated the permanent capital until 1881, five years after Colorado became a state.

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. That administrative union was renamed as Papua New Guinea in 1971. Notwithstanding that it was part of an administrative union, the Territory of Papua at all times retained a distinct legal status and identity; it was a Possession of the Crown whereas the Territory of New Guinea was initially a League of Nations mandate territory and subsequently a United Nations trust territory. This important legal and political distinction remained until the advent of the Independent State of Papua New Guinea in 1975.

paragraph_text: The history of El Salvador begins with several Mesoamerican nations, especially the Cuzcatlecs, as well as the Lenca and Maya. In the early 16th century, the Spanish Empire conquered the territory, incorporating it into the Viceroyalty of New Spain ruled from Mexico City. In 1821, the country achieved independence from Spain as part of the First Mexican Empire, only to further secede as part of the Federal Republic of Central America in 1823. Upon the republic's dissolution in 1841, El Salvador became sovereign until forming a short - lived union with Honduras and Nicaragua called the Greater Republic of Central America, which lasted from 1895 to 1898.

paragraph_text: Puerto Rico has been discussed as a potential 51st state of the United States. In a 2012 status referendum a majority of voters, 54%, expressed dissatisfaction with the current political relationship. In a separate question, 61% of voters supported statehood (excluding the 26% of voters who left this question blank).

paragraph_text: President McKinley signed a joint Congressional resolution demanding Spanish withdrawal and authorizing the President to use military force to help Cuba gain independence on April 20, 1898.. In response, Spain severed diplomatic relations with the United States on April 21. On the same day, the U.S. Navy began a blockade of Cuba. On April 23, Spain stated that it would declare war if the US forces invaded its territory. On April 25, the U.S. Congress declared that a state of war between the U.S. and Spain had de facto existed since April 21, the day the blockade of Cuba had begun. The United States sent an ultimatum to Spain demanding that it surrender control of Cuba, but due to Spain not replying soon enough, the United States had assumed Spain had ignored the ultimatum and continued to occupy Cuba.

paragraph_text: At the end of the war, the victorious powers sought to divide up the Ottoman Empire. Signed between the Allied and Associated Powers and Ottoman Empire at Sèvres on 10 August 1920, the Treaty of Sèvres promised to maintain the existence of the Armenian republic and to attach the former territories of Ottoman Armenia to it. Because the new borders of Armenia were to be drawn by United States President Woodrow Wilson, Ottoman Armenia was also referred to as "Wilsonian Armenia." In addition, just days prior, on 5 August 1920, Mihran Damadian of the Armenian National Union, the de facto Armenian administration in Cilicia, declared the independence of Cilicia as an Armenian autonomous republic under French protectorate.

paragraph_text: The Adams -- Onís Treaty of 1819, also known as the Transcontinental Treaty, the Florida Purchase Treaty, or the Florida Treaty, was a treaty between the United States and Spain in 1819 that ceded Florida to the U.S. and defined the boundary between the U.S. and New Spain. It settled a standing border dispute between the two countries and was considered a triumph of American diplomacy. It came in the midst of increasing tensions related to Spain's territorial boundaries in North America against the United States and Great Britain in the aftermath of the American Revolution; and also during the Latin American Wars of Independence. Florida had become a burden to Spain, which could not afford to send settlers or garrisons. Madrid decided to cede the territory to the United States through the Adams -- Onís Treaty in exchange for settling the boundary dispute along the Sabine River in Spanish Texas. The treaty established the boundary of U.S. territory and claims through the Rocky Mountains and west to the Pacific Ocean, in exchange for the U.S. paying residents' claims against the Spanish government up to a total of $5,000,000 and relinquishing the US claims on parts of Spanish Texas west of the Sabine River and other Spanish areas, under the terms of the Louisiana Purchase.

A tearful Lee Kuan Yew announced in a televised press conference that Singapore had become a sovereign, independent nation. In a widely remembered quote, he stated: "For me, it is a moment of anguish. All my life, my whole adult life, I have believed in merger and unity of the two territories." The new state became the Republic of Singapore, with Yusof bin Ishak appointed as its first President.

At the start of the American War of Independence in 1775, the British Empire included twenty colonies north and east of New Spain (present - day areas of Mexico and the Western United States). East and West Florida were ceded to Spain in the Treaty of Paris (1783) which ended the American Revolution, and then ceded by Spain to the United States in 1819. The remaining continental colonies of British North America formed the Dominion of Canada by uniting between 1867 and 1873. The Dominion of Newfoundland joined Canada in 1949.
