The American nation was born in the eighteenth century through revolution, independence and the creation of a new republic. The Declaration of Independence in 1776, the victory over British rule and the adoption of the United States Constitution established the political foundations of a country built around liberty, representation and national sovereignty.
During the nineteenth century, the United States expanded from a young Atlantic republic into a powerful continental nation. The Louisiana Purchase, westward expansion and the idea of Manifest Destiny extended American territory toward the Pacific, while exploration, settlement and railway construction reshaped the continent.
This period was also marked by deep conflict. Disputes over slavery, federal power and the future of the Union led to the American Civil War, one of the defining events in United States history. After reunification, rapid industrialization, technological development transformed America into a major economic and military power.
