Two caveats first: one, A History of Ukraine is a bit of a misnomer; “A political history of Ukrainian state-building“ would be closer to the mark. And two, this is not an academic work, but a very erudite long form essay.
This being said, said essay is compelling once you adjust to its scope, and there can be little doubt on its baseline historical quality considering Plokhy’s academic credentials are above reproach. It makes for excellent reading and does a lot to ground and contextualise the current events, which the book does not predict, but very much explains. If you are fuzzy about that whole “Ukraine” thing, or have been wondering if there is anything to current Russian claims (spoiler: no), this is recommended reading, caveats and all.
