  The Nazi party, which seized power in the 1933 German elections and maintained a dictatorship over much of Europe until the End of World War II on the European continent, deemed the Germans to be part of an Aryan " master race " (Herrenvolk), who therefore had the right to expand their territory and enslave or kill members of other races deemed inferior.
  
  The racial ideology conceived by the Nazis graded humans on a scale of pure Aryan to non-Aryan, with the latter viewed as subhuman. At the top of the scale of pure Aryans were Germans and other Germanic peoples including the Dutch, Scandinavians, and the English as well as other peoples such as some northern Italians and the French, who were said to have a suitable admixture of Germanic blood. Nazi policies labeled Romani people, people of color, and Slavs (mainly Poles, Serbs, Russians, Belarusians, Ukrainians and Czechs) as inferior non-Aryan subhumans. Jews were at the bottom of the hierarchy, considered inhuman and thus unworthy of life. In accordance with Nazi racial ideology, approximately six million Jews were killed in the Holocaust. 2.5 million ethnic Poles, 0.5 million ethnic Serbs and 0.2–0.5 million Romani were killed by the regime and its collaborators.
  
  The Nazis considered most Slavs to be non-Aryan Untermenschen. The Nazi Party's chief racial theorist, Alfred Rosenberg, adopted the term from Klansman Lothrop Stoddard 's 1922 book The Revolt Against Civilization: The Menace of the Under-man. In the secret plan Generalplan Ost ("Master Plan East") the Nazis resolved to expel, enslave, or exterminate most Slavic people to provide " living space " for Germans, but Nazi policy towards Slavs changed during World War II due to manpower shortages which necessitated limited Slavic participation in the Waffen-SS. Significant war crimes were committed against Slavs, particularly Poles, and Soviet POWs had a far higher mortality rate than their American and British counterparts due to deliberate neglect and mistreatment. Between June 1941 and January 1942, the Nazis killed an estimated 2.8 million Red Army POWs, whom they viewed as "subhuman".
  
  In the years 1943–1945, around 120,000 Polish people, mostly women and children, became the victims of ethnicity-based massacres by the Ukrainian Insurgent Army, which was then operating in the territory of occupied Poland. In addition to Poles who represented the vast majority of the murdered people, the victims also included Jews, Armenians, Russians, and Ukrainians who were married to Poles or attempted to help them.
  
  During the intensification of ties with Nazi Germany in the 1930s, Ante Pavelić and the Ustaše and their idea of the Croatian nation became increasingly race-oriented. The Ustaše view of national and racial identity, as well as the theory of Serbs as an inferior race, was influenced by Croatian nationalists and intellectuals from the end of the 19th and the beginning of the 20th century. Serbs were primary targets of racial laws and murders in the puppet Independent State of Croatia (NDH); Jews and Roma were also targeted. The Ustaše introduced laws to strip Serbs of their citizenship, livelihoods, and possessions. During the genocide in the NDH, Serbs suffered among the highest casualty rates in Europe during the World War II, and the NDH was one of the most lethal regimes in the 20th century.
  
  German praise for America's institutional racism was continuous throughout the early 1930s, and Nazi lawyers were advocates of the use of American models. Race based U.S. citizenship laws and anti-miscegenation laws (no race mixing) directly inspired the Nazi's two principal Nuremberg racial laws —the Citizenship Law and the Blood Law. Hitler's 1925 memoir Mein Kampf was full of admiration for America's treatment of "coloreds". Nazi expansion eastward was accompanied with invocation of America's colonial expansion westward, with the accompanying actions toward the Native Americans. In 1928, Hitler praised Americans for having "gunned down the millions of Redskins to a few hundred thousand, and now keeps the modest remnant under observation in a cage." On Nazi Germany's expansion eastward, in 1941 Hitler stated, "Our Mississippi must be the Volga."
  
  White supremacy was dominant in the U.S. from its founding up to the civil rights movement. On the U.S. immigration laws prior to 1965, sociologist Stephen Klineberg cited the law as clearly declaring "that Northern Europeans are a superior subspecies of the white race." While anti-Asian racism was embedded in U.S. politics and culture in the early 20th century, Indians were also racialized for their anticolonialism, with U.S. officials, casting them as a "Hindu" menace, pushing for Western imperial expansion abroad. The Naturalization Act of 1790 limited U.S. citizenship to whites only, and in the 1923 case, United States v. Bhagat Singh Thind, the Supreme Court ruled that high caste Hindus were not "white persons" and were therefore racially ineligible for naturalized citizenship. It was after the Luce–Celler Act of 1946 that a quota of 100 Indians per year could immigrate to the U.S. and become citizens. The Immigration and Nationality Act of 1965 dramatically opened entry to the U.S. to immigrants other than traditional Northern European and Germanic groups, and as a result would significantly alter the demographic mix in the U.S.
  
  Serious race riots in Durban between Indians and Zulus erupted in 1949. Ne Win 's rise to power in Burma in 1962 and his relentless persecution of "resident aliens" led to an exodus of some 300,000 Burmese Indians. They migrated to escape racial discrimination and wholesale nationalisation of private enterprises a few years later, in 1964. The Zanzibar Revolution of January 12, 1964, put an end to the local Arab dynasty. Thousands of Arabs and Indians in Zanzibar were massacred in riots, and thousands more were detained or fled the island. In August 1972, Ugandan President Idi Amin started the expropriation of properties owned by Asians and Europeans. In the same year, Amin ethnically cleansed Uganda's Asians, giving them 90 days to leave the country. Shortly after World War II, the South African National Party took control of the government in South Africa. Between 1948 and 1994, the apartheid regime took place. This regime based its ideology on the racial separation of whites and non-whites, including the unequal rights of non-whites. Several protests and violence occurred during the struggle against apartheid, the most famous of these include the Sharpeville Massacre in 1960, the Soweto uprising in 1976, the Church Street bombing of 1983, and the Cape Town peace march of 1989.
