White evangelical churches and organizations play a significant role in mobilizing congregants as participants in the white Christian nationalist movement. This fusion of faith and politics has made white evangelicals "ambassadors" of white Christian nationalism (Miller, 2022). This paper interrogates the history, theology, and politics of white Christian nationalism to understand its influence in the U. S. educational system, specifically its implications for K-12 history curriculum in public schools. Beginning with current legislation around critical race theory, this paper traces the intersection of evangelical and conservative discourse in the Southern United States. This historical analysis shows how the white, Southern evangelical record on race and racism accommodates the theopolitical ideology of the white Christian nationalist movement. This paper argues the current white evangelical challenges to critical race theory and demands to teach "alternative histories" about America's racial past not only limits discussions around race and power in classrooms but distorts the curriculum with white Christian nationalist tenets disguised as truth.
