After the Age of Discovery the British were one of the earliest and largest communities to emigrate out of Europe, and the British Empire's expansion during the first half of the 19th century saw an "extraordinary dispersion of the British people", with particular concentrations "in Australasia and North America". The British Empire was "built on waves of migration overseas by British people", who left the United Kingdom and "reached across the globe and permanently affected population structures in three continents". As a result of the British colonization of the Americas, what became the United States was "easily the greatest single destination of emigrant British". Historically in the 1790 United States Census estimate and presently in Australia, Canada and New Zealand "people of British origin came to constitute the majority of the population" contributing to these states becoming integral to the Anglosphere. There is also a significant population of people with British ancestry in South Africa. Colonial period An English presence in North America began with the Roanoke Colony and Colony of Virginia in the late-16th century, but the first successful English settlement was established in 1607, on the James River at Jamestown. By the 1610s, an estimated 1,300 English people had traveled to North America, the "first of many millions from the British Isles". In 1620 the Pilgrims established the English imperial venture of Plymouth Colony, beginning "a remarkable acceleration of permanent emigration from England" with over 60% of trans-Atlantic English migrants settling in the New England Colonies. During the 17th century, an estimated 350,000 English and Welsh migrants arrived in North America, which in the century after the Acts of Union 1707 was surpassed in rate and number by Scottish and Irish migrants. The British policy of salutary neglect for its North American colonies intended to minimize trade restrictions as a way of ensuring they stayed loyal to British interests. This permitted the development of the American Dream, a cultural spirit distinct from that of its European founders. The Thirteen Colonies of British America began an armed rebellion against British rule in 1775 when they rejected the right of the Parliament of Great Britain to govern them without representation; they proclaimed their independence in 1776, and subsequently constituted the first thirteen states of the United States of America, which became a sovereign state in 1781 with the ratification of the Articles of Confederation. The 1783 Treaty of Paris represented
