After hearing stories as a child about racial violence in Tulsa in 1921, Ellsworth began researching the massacre for his senior thesis at Reed College, which he later turned into Death in a Promised Land. Based on both traditional archival research and on interviews with elderly massacre survivors, the book was the first-ever comprehensive history of what was the single worst incident of racial violence in American history, one which resulted in more than 1000 African American homes and businesses being looted and burned to the ground by white mobs, while an unknown number of people were killed. In 2021, Ellsworth published
The Ground Breaking: An American City and Its Search for Justice, the story of how the history of the massacre had been suppressed for more than fifty years, and how the story finally came to light.
The Ground Breaking was longlisted for the
National Book Award for Nonfiction, and the
Harriet Beecher Stowe Book Award for Literary Activism. While serving as a historian for the Tulsa Race Riot Commission, Ellsworth initiated the search for the unmarked graves of massacre victims in 1999, and remains involved in the ongoing search. ==
