The United States of American began on June 12, 1788 when New Hampshire became the ninth state to ratify the US Constitution. The colonies declared their independence from Britain on July 4, 1776, but it a took a long war to actually attain independence. On October 19, 1781 , Lord Cornwallis surrendered his army to Washington, but it was not until September 3, 1783 that the treaty ending the war was signed and Britain conceded American independence. Until the constitution was ratified the colonies governed themselves as separate states.
