Enclave and exclaveAn enclave is a territory (or a small territory as part of a larger one) that is entirely surrounded by the territory of one other state or entity. Enclaves may also exist within territorial waters. Enclave is sometimes used improperly to denote a territory that is only partly surrounded by another state. Vatican City and San Marino, both enclaved by Italy, and Lesotho, enclaved by South Africa, are completely enclaved sovereign states.
U.S. stateIn the United States, a state is a constituent political entity, of which there are 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory where it shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside.
Indian TerritoryThe Indian Territory and the Indian Territories are terms that generally described an evolving land area set aside by the United States government for the relocation of Native Americans who held original Indian title to their land as a sovereign independent state. The tribes ceded land they occupied in exchange for land grants in 1803. The concept of an Indian Territory was an outcome of the U.S. federal government's 18th- and 19th-century policy of Indian removal. After the American Civil War (1861–1865), the policy of the U.
Emancipation ProclamationThe Emancipation Proclamation, officially Proclamation 95, was a presidential proclamation and executive order issued by United States President Abraham Lincoln on January 1, 1863, during the American Civil War. The Proclamation changed the legal status of more than 3.5 million enslaved African Americans in the secessionist Confederate states from enslaved to free. As soon as slaves escaped the control of their enslavers, either by fleeing to Union lines or through the advance of federal troops, they were permanently free.
Treaty of Guadalupe HidalgoThe Treaty of Guadalupe Hidalgo officially ended the Mexican–American War (1846–1848). It was signed on 2 February 1848 in the town of Guadalupe Hidalgo. After the defeat of its army and the fall of the capital in September 1847, Mexico entered into peace negotiations with the U.S. envoy, Nicholas Trist. The resulting treaty required Mexico to cede 55 percent of its territory including the present-day states of California, Nevada, Utah, and most of Colorado, New Mexico, and Arizona.
UnicameralismUnicameralism (from uni- "one" + Latin camera "chamber") is a type of legislature, which consists of one house or assembly, that legislates and votes as one. Unicameralism has become an increasingly common type of legislature, making up nearly 60% of all national legislatures and an even greater share of subnational legislatures. Sometimes, as in New Zealand and Denmark, unicameralism comes about through the abolition of one of two bicameral chambers, or, as in Sweden, through the merger of the two chambers into a single one, while in others a second chamber has never existed from the beginning.
