# The Chronicle of United States: From Indigenous homelands to a continental republic and global superpower. History of United States: From Indigenous homelands to a continental republic and global superpower. 6 eras and 26 sourced events, every claim traceable… Canonical: https://terralore.co/country/USA/chronicle Updated: 2026-09-07 Founding: Declaration of Independence — 4 July 1776. On 4 July 1776 the Second Continental Congress adopted the Declaration of Independence, announcing the separation of thirteen British colonies from Great Britain. A durable framework of government followed: the Constitution was signed on 17 September 1787 and, after New Hampshire became the ninth state to ratify on 21 June 1788, took effect when the new federal government convened on 4 March 1789, with George Washington inaugurated as first president on 30 April 1789. The history of the United States spans the deep antiquity of Indigenous nations who peopled the continent for many thousands of years, the violent disruption of European colonisation, and the birth of a self-governing republic in the late eighteenth century. Founded on a Declaration that proclaimed human equality while tolerating slavery and the dispossession of Native peoples, the nation expanded across a continent, fractured in a civil war over human bondage, and reconstructed itself around abolition and citizenship. Industrialisation, mass immigration, and two world wars carried the United States to the centre of world affairs, where its mid-twentieth-century civil rights struggles and Cold War rivalry reshaped both its domestic order and the international system.

Leader of the alliance of Algonquian-speaking peoples whose lands surrounded Jamestown, navigating trade, diplomacy, and conflict with the early English colonists. ## Revolution and the founding of the Republic — 1763 – 1815 Resistance to British taxation grew into a war of independence and the creation of a new kind of state: a large federal republic governed by a written constitution. - 4 July 1776: **Declaration of Independence** — The Second Continental Congress adopted the Declaration of Independence, formally announcing the separation of the thirteen colonies from Great Britain.

Seward agreed to buy Russian America — the colony Russia had run from Sitka through the Russian-American Company since 1799 — for $7.2 million, proposed by the Russian minister in Washington, Eduard de Stoeckl: less than two cents an acre for nearly 600,000 square miles. Russia lacked the money to settle or defend the territory and its defeat in the Crimean War had further reduced its interest. The Senate approved the treaty on 9 April, Tsar Alexander II ratified it on 20 June, and Alaska was formally transferred at Sitka on 18 October 1867. Skeptics dubbed the purchase 'Seward's Folly' or 'Seward's Icebox'; the Treasury warrant for seven million two hundred thousand dollars was issued on 1 August 1868.
