Pekka Hämäläinen (historian)

In 2022, Hämäläinen published Indigenous Continent: The Epic Contest for North America. This work aims to recast the history of the conquest of North America, in which Native Americans are assumed as destined to be conquered by the encroachment of European civilization, by emphasizing the considerable political and military power of various indigenous empires, such as the Great Sioux Nation and the Comanche empire. The critical reception of Hämäläinen's book has been mixed. The book was praised by historians like Elizabeth Fenn and Elliott West, but indigenous historians and Native Studies academics like Sweet and Ned Blackhawk (Western Shoshone) criticized the book. In an interview with the New York Times, Blackhawk dismissed Hamalainen as an historian of "equestrianism" and objected to the book's "occasional disregard of things like law and policy, which are central to Native American sovereignty and lives." UNC historian Kathleen DuVal also criticized the book for not paying sufficient attention to the role of women in indigenous-colonial conflict.

In 2019, Hämäläinen published Lakota America: A New History of Indigenous Power, covering the history of the Lakota people from the 17th-20th centuries; the book claims similarly that the Lakota constituted an empire. The book was criticized by indigenous academics such as Rutgers University historian Jameson "Jimmy" Sweet (Lakota/Dakota) and author Delphine Red Shirt (Oglala Lakota). Historian Nick Estes has also criticized the book, described Hämäläinen's work as "post-modern cultural relativism at its worst", and Jameson Sweet rejected the idea of the Lakota as an empire, insisting that the Lakota were "a desperate people trying to survive and adapt to a turbulent world brought on by settler colonialism".

His 2008 book The Comanche Empire was positively reviewed and won the Bancroft Prize. The book argued that the Comanche occupation of the Southern Plains from the late 18th to early 19th centuries constituted an empire.

He graduated from University of Helsinki, with a Ph.D. in 2001. He taught at Texas A&M University from 2002 to 2004. His work has appeared in the American Historical Review, Journal of American History, William and Mary Quarterly, and the Western Historical Quarterly. He taught in the History Department at University of California, Santa Barbara, before he moved to Oxford University.

In the late 2000s, Hamalainen's work focused on equestrianism in the American plains and southwest borderlands.
