His research interests focus on the political and diplomatic history of the early Soviet state and Stalin period. Peter's next project will explore how the Soviet-Polish War was understood and articulated by the Soviet elite and what impact this had on the evolution of the Soviet state in the 1920s. Rather than analyse the Soviet-Polish War just as a military campaign, the project will focus on how the aftershocks of war contributed to the emergence of the Stalinist system and the transformation of the Revolution.
