Indigenous peoples lived in what is now the United States for thousands of years and developed complex cultures before European colonists began to arrive, mostly from England, after 1600. The Spanish had small settlements inFlorida and the Southwest, and the French along the Mississippi River and the Gulf Coast. By the 1770s, thirteen British colonies contained two and a half million people along the Atlantic coast east of the Appalachian Mountains. In the 1760s the British government imposed a series of new taxes while rejecting the American argument that any new taxes had to be approved by the people. Tax resistance, especially the Boston Tea Party (1774), led to punitive laws (the Intolerable Acts) by Parliament designed to end self-government in Massachusetts. American Patriots (as they were called at the time as a term of ridicule) adhered to a political ideology called republicanism that emphasized civic duty, virtue, and opposition to corruption, fancy luxuries and aristocracy.
All thirteen colonies united in a Congress that called on the colonies to write new state constitutions. After armed conflict began in Massachusetts, Patriots drove the royal officials out of every colony and assembled in mass meetings and conventions. Those Patriot governments in the colonies unanimously empowered their delegates to Congress to declare independence. In 1776, Congress created an independent nation, the United States of America.
