Harvard historian who argued Chernobyl was a direct cause of the Soviet collapse

The fall of the Soviet Union would be grossly incomplete without the Chernobyl story.

A historian who serves as the Mykhailo Hrushevsky Professor of Ukrainian History at Harvard University and directed the Harvard Ukrainian Research Institute (2013–2025), Plokhy has devoted his career to the intellectual, cultural, and international history of Eastern Europe and the Cold War. His 2018 book Chernobyl: History of a Tragedy won the Baillie Gifford Prize and argued that the nuclear disaster catalyzed glasnost, mobilized Ukraine's independence movement, and was a direct cause of the Soviet Union's collapse. Through works including The Last Empire, The Gates of Europe, and The Russo-Ukrainian War, he has reshaped the historiography of the Soviet dissolution and East Slavic national identity, becoming the most influential synthesizer of Chernobyl's place in modern history.

Chernobyl and the Crisis of the Soviet System

In Chernobyl: History of a Tragedy, Plokhy presents the 1986 nuclear accident not simply as a technical failure but as an event that exposed structural flaws in the Soviet political system and nuclear industry. The immediate cause was a turbine test gone wrong, while he locates deeper causes in the character of the Soviet system and the industry's deficiencies. The book also recounts the experiences of firefighters, scientists, engineers, workers, soldiers, and police involved in containing the disaster. In Plokhy's account, the aftermath exposed vulnerabilities in Soviet governance and contributed to hastening the Soviet Union's dissolution; this is not the same as treating Chernobyl as its sole cause. The book won the 2018 Baillie Gifford Prize for Non-Fiction.
