when did the united states became a state
History of the United States Armed conflict began in 1775. In 1776, the Second Continental Congress declared a new, independent nation: the United States of America. Led by General George Washington, it won the Revolutionary War with large support from France. The peace treaty of 1783 gave the new nation the land east of the Mississippi River (except Canada and Florida). The Articles of Confederation established a central government, but it was ineffectual at providing stability, as it could not collect taxes and had no executive officer. A convention in 1787 wrote a new Constitution that was adopted in 1789. In 1791, a Bill of Rights was added to guarantee inalienable rights. With Washington as the first president and Alexander Hamilton his chief adviser, a strong central government was created. Purchase of the Louisiana Territory from France in 1803 doubled the size of the United States. A second and final war with Britain was fought in 1812, which solidified national pride.
United States Paleo-Indians migrated from Siberia to the North American mainland at least 15,000 years ago.[20] European colonization began in the 16th century. The United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, and the subsequent Declaration of Independence in 1776. The war ended in 1783 with the United States becoming the first country to gain independence from a European power.[21] The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties. The United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories,[22] displacing Native American tribes, and gradually admitting new states until it spanned the continent by 1848.[22] During the second half of the 19th century, the Civil War led to the abolition of slavery.[23][24] By the end of the century, the United States had extended into the Pacific Ocean,[25] and its economy, driven in large part by the Industrial Revolution, began to soar.[26] The Spanish–American War and World War I confirmed the country's status as a global military power. The United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, and a permanent member of the United Nations Security Council. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 moon landing. The end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower.[27]
Territory of Alaska The Territory of Alaska or Alaska Territory was an organized incorporated territory of the United States that existed from August 24, 1912, until January 3, 1959, when it was admitted to the Union as the State of Alaska. The territory was created as the District of Alaska on May 17, 1884.
American Revolution Tensions erupted into battle between Patriot militia and British regulars when the king's army attempted to capture and destroy Colonial military supplies at Lexington and Concord on April 19, 1775. The conflict then developed into a global war, during which the Patriots (and later their French, Spanish, and Dutch allies) fought the British and Loyalists in what became known as the American Revolutionary War (1775â€“83). Each of the thirteen colonies formed a Provincial Congress that assumed power from the old colonial governments and suppressed Loyalism, and from there they built a Continental Army under the leadership of General George Washington. The Continental Congress determined King George's rule to be tyrannical and infringing the colonists' rights as Englishmen, and they declared the colonies free and independent states on July 2, 1776. The Patriot leadership professed the political philosophies of liberalism and republicanism to reject monarchy and aristocracy, and they proclaimed that all men are created equal.
