Dr. Ivan Sablin is a leader of the Research Group “Entangled Parliamentarisms: Constitutional Practices in Russia, Ukraine, China and Mongolia, 1905–2005” at Heidelberg University in Germany. His research interests include history of the Russian Empire and the Soviet Union, with special attention to Siberia and the Russian Far East, histories of parliaments, empires, and diversity, and global intellectual history. He is an author of two monographs – Governing Post-Imperial Siberia and Mongolia, 1911–1924 (London: Routledge, 2016) and The Rise and Fall of Russia’s Far Eastern Republic, 1905–1922 (London: Routledge, 2018). Currently, I work on a monograph devoted to the conceptual and institutional history of parliaments in Russia and the Soviet Union between 1905 and 1955. Within his time as a Visiting Fellow at the Institute of Contemporary History in Ljubljana, Dr. Sablin engages in comparative studies of parliamentarism, federalism, and other concepts under state socialism in a global context, comparing concepts pertaining to parliaments and parliamentary institutions in Yugoslavia, Czechoslovakia, and the USSR between the 1960s and 1991.
