We have divided this society into a number of specific contact situations: (1) isolated and less colonial states: (2) states initially controlled by adjacent powers; (3) those dominated by invading whites; and, (4) the most colonial, involving slavery and high levels of racial conflict. Essentially, these situational types may be arranged along a colonial continuum, ranging from low to high colonialism and associated levels of intergroup conflict. This view is based on the notion that the more features of the colonial process are present in a particular context, the more conflict-ridden intergroup relations within them tend to be.
