The Russian delegation and the members of the General Secretariat along with Mykhailo Hrushevsky after some discussion worked out the new Universal of the UPR and the Declaration of the Russian Provisional Government that were announced on July 3.
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.
Other topics where he has produced monographs include such topics as "The Ukrainian diaspora in Russia", Ivan Franko, Mykhailo Hrushevsky, Lesia Ukrainka, Hryhory Skovoroda, the development of religious thought in Ukraine.
