When the Pilgrims came to New England they too were coming not to vacant land but to territory inhabited by tribes of Indians. The governor of the Massachusetts Bay Colony, John Winthrop, created the excuse to take Indian land by declaring the area legally a "vacuum." The Indians, he said, had not "subdued" the land, and therefore had only a "natural" right to it, but not a "civil right." A "natural right" did not have legal standing.
The Puritans also appealed to the Bible, Psalms 2:8: "Ask of me, and I shall give thee, the heathen for thine inheritance, and the uttermost parts of the earth for thy possession." And to justify their use of force to take the land, they cited Romans 13:2: "Whosoever therefore resisteth the power, resisteth the ordinance of God: and they that resist shall receive to themselves damnation."

The Indian population of 10 million that lived north of Mexico when Columbus came would ultimately be reduced to less than a million. Huge numbers of Indians would die from diseases introduced by the whites. A Dutch traveler in New Netherland wrote in 1656 that "the Indians . . . affirm, that before the arrival of the Christians, and before the smallpox broke out amongst them, they were ten times as numerous as they now are, and that their population had been melted down by this disease, whereof nine-tenths of them have died." When the English first settled Martha's Vineyard in 1642, the Wampanoags there numbered perhaps three thousand. There were no wars on that island, but by 1764, only 313 Indians were left there. Similarly, Block Island Indians numbered perhaps 1,200 to 1,500 in 1662, and by 1774 were reduced to fifty-one.
Behind the English invasion of North America, behind their massacre of Indians, their deception, their brutality, was that special powerful drive born in civilizations based on private property. It was a morally ambiguous drive; the need for space, for land, was a real human need. But in conditions of scarcity, in a barbarous epoch of history ruled by competition, this human need was transformed into the murder of whole peoples.
Excerpts from A People's History of the United States, by Howard Zinn:
If you want to take a sort of clinical historical approach, you could say that the Native Americans simply lost a war. I don't think there's one bit of inhabited land on the planet that at some point was not forcibly taken from some group to be inhabited by another.
