Indigenous and European contact
Further information: Pre-Columbian era and Colonial history of the United States
The first inhabitants of North America migrated from Siberia by way of the Bering land bridge and arrived at least 15,000 years ago, though increasing evidence suggests an even earlier arrival.^[28] Some, such as the pre-Columbian Mississippian culture, developed advanced agriculture, grand architecture, and state-level societies. After the Spanish conquistadors made the first contacts, the native population declined for various reasons, primarily diseases such as smallpox and measles. Violence was not a significant factor in the overall decline, though it impacted specific tribes and colonial settlements.^{[54][55][56][57][58][59]} In the Hawaiian Islands the earliest indigenous inhabitants arrived around 1 AD from Polynesia. Captain James Cook arrived in the Hawaiian Islands in 1778^[60] with American contact made in 1790 with the first ship to dock arriving in Oahu.^[61]
In the early days of colonization many European settlers were subject to food shortages, disease, and attacks from Native Americans. Native Americans were also often at war with neighboring tribes and allied with Europeans in their colonial wars.^[62] At the same time, however, many natives and settlers came to depend on each other. Settlers traded for food and animal pelts, natives for guns, ammunition and other European wares.^[63]Natives taught many settlers where, when and how to cultivate corn, beans and squash. European missionaries and others felt it was important to "civilize" the Indians and urged them to adopt European agricultural techniques and lifestyles.^[64][65]
Settlements

After Columbus' first voyage to the New World in 1492, other explorers followed with settlement into the Floridas and the American Southwest.^[66][67] There were also some French attemptsto colonize the east coast, and later more successful settlements along the Mississippi River. Successful English settlement on the eastern coast of North America began with the Virginia Colony in 1607 at Jamestown and the Pilgrims' Plymouth Colony in 1620. Early experiments in communal living failed until the introduction of private farm holdings.^[68] Many settlers weredissenting Christian groups who came seeking religious freedom. The continent's first elected legislative assembly, Virginia's House of Burgesses created in 1619, and the Mayflower Compact, signed by the Pilgrims before disembarking, established precedents for the pattern of representative self-government and constitutionalism that would develop throughout the American colonies.^[69][70]

Most settlers in every colony were small farmers, but other industries developed within a few decades as varied as the settlements. Cash cropsincluded 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.^[71] Cities eventually dotted the coast to support local economies and serve as trade hubs. English colonists were supplemented by waves of Scotch-Irish and other groups. As coastal land grew more expensive freedindentured servants pushed further west.^[72]
Slave cultivation of cash crops began with the Spanish in the 1500s, and was adopted by the English, but life expectancy was much higher in North America because of less disease and better food and treatment, leading to a rapid increase in the numbers of slaves.^[73][74][75] Colonial society was largely divided over the religious and moral implications of slavery and colonies passed acts for and against the practice.^[76][77] But by the turn of the 18th century, African slaves were replacing indentured servants for cash crop labor, especially in southern regions.^[78]
With the British colonization of Georgia in 1732, the 13 colonies that would become the United States of America were established.^[79] All had local governments with elections open to most free men, with a growing devotion to the ancient rights of Englishmen and a sense of self-government stimulating support for republicanism.^[80] With extremely high birth rates, low death rates, and steady settlement, the colonial population grew rapidly. Relatively small Native American populations were eclipsed.^[81] The Christian revivalistmovement of the 1730s and 1740s known as the Great Awakening fueled interest in both religion and religious liberty.^[82]
In 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, those 13 colonies had a population of over 2.1 million in 1770, about one-third that of Britain. Despite continuing new arrivals, the rate of natural increase was such that by the 1770s only a small minority of Americans had been born overseas.^[83] The colonies' distance from Britain had allowed the development of self-government, but their success motivated monarchs to periodically seek to reassert royal authority.^[84]
