by creating permanent images of a controlled white citizenry juxtaposed to images of helpless and powerless black men." School curriculum White supremacy has also played a part in U.S. school curriculum. Over the course of the 19th, 20th, and 21st centuries, material across the spectrum of academic disciplines has been taught with a heavy emphasis on White culture, contributions, and experiences, and a lack of representation of non-White groups' perspectives and accomplishments. In the 19th century, Geography lessons contained teachings on a fixed racial hierarchy, which white people topped. Mills (1994) writes that history as it is taught is really the history of White people, and it is taught in a way that favors White Americans and White people in general. He states that the language used to tell history minimizes the violent acts committed by White people over the centuries, citing the use of the words, for example, "discovery," "colonization," and "New World" when describing what was ultimately a European conquest of the Western Hemisphere and its indigenous peoples. Swartz (1992) seconds this reading of modern history narratives when it comes to the experiences, resistances, and accomplishments of Black Americans throughout the Middle Passage, slavery, Reconstruction, Jim Crow, and the Civil rights movement. In an analysis of American history textbooks, she highlights word choices that repetitively "normalize" slavery and the inhumane treatment of Black people. She also notes the frequent showcasing of White abolitionists and actual exclusion of Black abolitionists and the fact that Black Americans had been mobilizing for abolition for centuries before the major White American push for abolition in the 19th century. She ultimately asserts the presence of a masternarrative that centers Europe and its associated peoples (White people) in school curriculum, particularly as it pertains to history. She writes that this masternarrative condenses history into only history that is relevant to, and to some extent beneficial for, White Americans. Elson (1964) provides detailed information about the historic dissemination of simplistic and negative ideas about non-White races. Native Americans, who were subjected to attempts of cultural genocide by the U.S. government through the use of American Indian boarding schools, were characterized as homogenously "cruel," a violent menace toward White Americans, and lacking civilization or societal complexity (p. 74). For example, in the 19th century, Black Americans were consistently portrayed as lazy, immature, and intellectually and morally inferior to white Americans, and in many ways not deserving
