Authors such as Hannah Arendt, in her 1951 book "The Origins of Totalitarianism", have said that the racist ideology ("popular racism") which developed at the end of the 19th century helped legitimize the imperialist conquests of foreign territories and the atrocities that sometimes accompanied them (such as the Herero and Namaqua Genocide of 1904–1907 or the Armenian Genocide of 1915–1917). Rudyard Kipling's poem, "The White Man's Burden" (1899), is one of the more famous illustrations of the belief in the inherent superiority of the European culture over the rest of the world, though it is also thought to be a satirical appraisal of such imperialism. Racist ideology thus helped legitimize the conquest and incorporation of foreign territories into an empire, which were regarded as a humanitarian obligation partially as a result of these racist beliefs.
