As a political ideology, it imposes and maintains cultural, social, political, historical or institutional domination by white people and non-white supporters. In the past, this ideology had been put into effect through socioeconomic and legal structures such as the Atlantic slave trade, colonial labor and social practices, the Scramble for Africa, Jim Crow laws in the United States, the activities of the Native Land Court in New Zealand,[4] the White Australia policies from the 1890s to the mid-1970s, and apartheid in South Africa.[5][6] This ideology is also today present among neo-Confederates.
