Omeljan Pritsak (7 April 1919, Luka, Sambir County, eastern Galicia – 29 May 2006, Boston, Massachusetts, U.S.) was the first Mykhailo Hrushevsky Professor of Ukrainian History at Harvard University and the founder and first director (1973-1989) of the Harvard Ukrainian Research Institute.
Pritsak began his academic career at the University of Lviv in interwar Poland where he studied Middle Eastern languages under local orientalists and became associated with the Shevchenko Scientific Society and attended its seminar on Ukrainian history led by Ivan Krypiakevych. After the Soviet annexation of Galicia, he moved to Kyiv where he briefly studied with the premier Ukrainian orientalist, Ahatanhel Krymsky. During the war, Pritsak escaped to the west. He studied at the universities in Berlin and Göttingen, receiving a doctorate from the latter, before teaching at the University of Hamburg. In the 1960s, he moved to the United States, where he taught at the University of Washington for a while, before moving to Harvard at the invitation of the prominent linguist, Roman Jakobson, who was interested in proving the authenticity of the twelfth century "Song of Igor" through the use of oriental sources. At Harvard, he founded the Harvard Ukrainian Research Institute (1973), became the first Mykhailo Hrushevsky Professor of Ukrainian History (1975), and started the journal, Harvard Ukrainian Studies (1977ff). In 1989, he retired from his Harvard professorship. After the emergence of an independent Ukraine in 1991, Pritsak returned to Kyiv where he founded the Oriental Institute of the National Academy of Sciences and the journal Skhidnyi svit (The Oriental World). He spent his final years back in the United States, and died in Boston at the age of 87.
Main Interests 
Pritsak was a medievalist who specialized in the use of oriental, especially Turkic, sources for the history of Kyivan Rus', early modern Ukraine, and the European Steppe region. He was also a student of Old Norse and was familiar with Scandinavian sources for the history of Kyivan Rus'. His magnum opus, The Origin of Rus', only one volume of which has appeared in English (1981), inclines toward, but does not totally adopt, a Normanist interpretation of Rus' origins. He saw Kyivan Rus' as a multi-ethnic polity.
In addition to the early Rus', Pritsak's works focused on Eurasian nomads and steppe empires such as those created by the Bulgars, Khazars, Pechenegs, and Kipchaks. However, he firmly rejected the "Eurasian" approach to Ukrainian and Russian history and would have nothing to do with its Russian nationalist postulates.
Ukrainian Historian 
Unlike his predecessors Mykhailo Hrushevsky, Dmytro Doroshenko, and Ivan Krypiakevych, who wrote national histories or histories of the Ukrainian people, Pritsak followed the Ukrainian historian of Polish background, Viacheslav Lypynsky, in proposing the ideal of writing a "territorialist" history of Ukraine which would include the Polish, Turkic, and other peoples that have inhabited the country from ancient times. This idea was later taken up by his younger contemporary Paul Magocsi, who was for some time an associate of the Harvard Ukrainian Institute.
Pritsak was a political conservative and during his youth in eastern Galicia under the Polish Republic, and later also during the Cold War was a supporter of the conservative "Hetmanite" or monarchist movement among Ukrainians. This led him to criticize Hrushevsky's political radicalism and historical populism, although, ironically, he claimed that Hrushevsky's "school" of history was being continued at Harvard. Also during the Cold War, Pritsak became prominent in the movement towards Ukrainian-Jewish reconciliation.
