For the better part of the last decade, Megan Threlkeld has been leading students on a tour of a nation at war with its past. 

Threlkeld, a history professor at Denison University in Ohio, teaches a seminar for first-year students focused on how American history has been taught through the centuries, parsing textbooks to explain how national narratives evolve. The course dissects some of the country’s most notorious battles in the great culture war over historical memory — from the 1990s-era clashes about how to commemorate the atomic bombings of Hiroshima and Nagasaki to the conservative uproar in the mid-2010s over a U.S. history course framework emphasizing the country’s legacy of racism. The last few years of her course have coincided with a new front in America’s culture wars: how this legacy is discussed in public schools.  

Since 2021, at least 18 states have passed laws banning schools from teaching critical race theory or “divisive concepts” about racism and sexism. In the same period, universities and colleges have become a key battleground for conservative lawmakers intent on codifying an “anti-woke” view of history in the classroom, with nearly two dozen states introducing bills targeting history instruction and diversity training in higher education. 

Threlkeld’s students have been studying these fights in real time and reflecting on the future of a country afraid of its past. I spoke to her about what they make of this fraught political moment and the continuities between history wars of the past and present.
