Timeline of events (pre-2017)
The nation was founded by thirteen colonies of Great Britain located along the Atlantic coast who issued a Declaration of Independence from Great Britain on July 4, 1776. This led to the American Revolution, the first successful colonial war of independence. The Philadelphia Convention adopted the current U.S. Constitution on September 17, 1787, and its ratification the following year made the states part of constitutional federal republic. The Bill of Rights, a set of ten amendments that guarantee fundamental civil rights and freedoms, was ratified in 1791.
The United States acquired land from France (the Louisiana Purchase), Spain (the present-day state of Florida), the United Kingdom, Mexico (the present-day states of New Mexico and Arizona), and Russia (the present-day state of Alaska) in the 19th century. Annexation of the Republic of Texas and Republic of Hawaii also took place. Disputes between the southern states and the northern states over slavery and states' rights ultimately provoked the American Civil War (1861 - 1865). The Civil War ended in a northern victory, preserving the nation and ending legal slavery in the United States.
The economy was prosperous in the 1870s with the expansion of the railroad and steel industries. The Spanish-American War and World War I confirmed the country's status as a military superpower. The bombings of Hiroshima and Nagasaki, Japan in 1945 were conducted by the US during World War II, making the US the first to have nuclear weapons.
In the years after WWII, the US was a founding member of NATO, a member of the United Nations Security Council, and a rival with the Soviet Union during the Cold War. The Soviet Union's dissolution in 1991 marked the end of the Cold War, and the US was left as the sole superpower nation.
