New York. Vereinigte Staaten. Many settlers were dissenting Christian groups who came seeking religious freedom. The continent's first elected legislative assembly, Virginia's House of Burgesses , was created in The Mayflower Compact , signed by the Pilgrims before disembarking, and the Fundamental Orders of Connecticut , established precedents for the pattern of representative self-government and constitutionalism that would develop throughout the American colonies.
Most settlers in every colony were small farmers, though other industries were formed. Cash crops included tobacco, rice, and wheat. Extraction industries grew up in furs, fishing and lumber.
Manufacturers produced rum and ships, and by the late colonial period, Americans were producing one-seventh of the world's iron supply.
English colonists were supplemented by waves of Scotch-Irish immigrants and other groups. As coastal land grew more expensive, freed indentured servants claimed lands further west.
A large-scale slave trade with English privateers began. With the establishment of the Province of Georgia in , the 13 colonies that would become the United States of America were administered by the British as overseas dependencies.
Relatively small Native American populations were eclipsed. During the Seven Years' War known in the United States as the French and Indian War , British forces seized Canada from the French, but the francophone population remained politically isolated from the southern colonies.
Excluding the Native Americans , who were being conquered and displaced, the 13 British colonies had a population of over 2.

During his third and final voyage , Captain James Cook became the first European to begin formal contact with Hawaii.
The American Revolutionary War was the first successful colonial war of independence against a European power. Americans had developed an ideology of " republicanism " asserting that government rested on the will of the people as expressed in their local legislatures.

With the election of Republican Abraham Lincoln , conventions in thirteen slave states ultimately declared secession and formed the Confederate States of America the "South" or the "Confederacy" , while the federal government the " Union " maintained that secession was illegal.
The ensuing war would become the deadliest military conflict in American history, resulting in the deaths of approximately , soldiers as well as many civilians.

The government enacted three constitutional amendments in the years after the war: the aforementioned Thirteenth as well as the Fourteenth Amendment providing citizenship to the nearly four million African Americans who had been slaves,  and the Fifteenth Amendment ensuring in theory that African Americans had the right to vote.
The war and its resolution led to a substantial increase in federal power  aimed at reintegrating and rebuilding the South while guaranteeing the rights of the newly freed slaves.
Reconstruction began in earnest following the war. While President Lincoln attempted to foster friendship and forgiveness between the Union and the former Confederacy, his assassination on April 14, , drove a wedge between North and South again.
Republicans in the federal government made it their goal to oversee the rebuilding of the South and to ensure the rights of African Americans.
They persisted until the Compromise of when the Republicans agreed to cease protecting the rights of African Americans in the South in order for Democrats to concede the presidential election of Southern white Democrats, calling themselves " Redeemers ," took control of the South after the end of Reconstruction.

The United States played a leading role in the Bretton Woods and Yalta conferences with the United Kingdom, the Soviet Union, and other Allies, which signed agreements on new international financial institutions and Europe's postwar reorganization.
