Erez Manela is Professor of History at Harvard University, where he teaches international history and the history of the United States in the world. He also serves as Director of Graduate Programs at Harvard's Weatherhead Center for International Affairs and co-chairs the Harvard International and Global History Seminar (HIGHS).

He is best known for the prize-winning book The Wilsonian Moment: Self-Determination and the International Origins of Anticolonial Nationalism, which showed how U.S. attempts to recast international order in the wake of World War I helped spark upheavals across the colonial world in 1919 and beyond.

He has also studied the history of the World Health Organization's global smallpox eradication program in the 1960s and '70s and what it tells us about the intersection of superpower relations, international development, and international organizations in that era.

His current work examines how World War II transformed Americans' relationship with the Global South.

Manela has held fellowships from the National Endowment for the Humanities, the American Academy of Arts & Sciences, and the American Council of Learned Societies, among others, and was a Burkhardt Fellow at the Radcliffe Institute for Advanced Study. He also co-edits a book series on Global and International History for Cambridge University Press.
