On a recent afternoon in Kyiv, a professor of literature and a stand-up comedian ​got together to talk about Russian colonialism, a subject that has become ​a preoccupation among Ukrainian activists, cultural figures and bookstore owners.

​The moderator of the discussion, which was recorded for a new podcast for Ukraine’s national public broadcaster, was Mariam Naiem, a graphic designer and former philosophy student who has become an unlikely expert on the topic.

“This war is just the continuation of centuries of Russian colonization,” said Ms. Naiem, 32, ​referring to Russia’s full-scale invasion of Ukraine. “It’s the same playbook.”

Russia’s long cultural and political domination of Ukraine, first through its empire and then the Soviet Union, had left an indelible mark, the podcast guests agreed, as they lamented being more fluent in Russian poems and films than in their own nation’s cultural treasures.

The goal of the podcast, Ms. Naiem said, was to solve this problem and “talk about our personal and social path of decolonization.”

It may have seemed an odd moment of cultural introspection in a war-battered country with urgent problems like how to repel Russian troops advancing along the front line.
