Slavery started in colonies because the colony was mainly found by plants from the Barbados who brought large amounts of African slaves from the island to establish new plantations and to meet agricultural needs .
Turner's main point in his thesis was that the frontier played the most significant part in American History and that majority of history took place around the colonization of the West.
His arguments are considered innacurate because what mostly dominates American History are the Civil War, industrialization, slavery and immigration. He also ignores the existance of native americans who lived out of the settled area.
