This paper examines 126 research articles from three comparative education journals to chart the development of knowledge within comparative education on the Soviet Union and post-Soviet countries. Thematic, theoretical, discursive, and methodological aspects of scholarship are linked with changing geopolitical realities in a systematic analysis of scholarship published since the late 1950s. A new framework of multi-layered colonialism is introduced to explore different features of the double disadvantage that comparative education knowledge production on post-Soviet countries has faced--Russian imperialism and Western academic colonialism. The paper contributes to comparative education knowledge creation by historicising our understanding of Western academic output and outlining a potential future direction in the development of knowledge on post-Soviet systems, policies, and practices of education.
