Ukraine

On 24 February 2022, Russian forces invaded Ukraine. Four years on, the war grinds on — hundreds of thousands dead, a continent reshaped, and a causal chain that traces back to a suitcase in Taiwan.

A boy tsar in 1613, a revolutionary pamphlet in 1848, a president's flight in 2014 — all on 21 February, all part of the same unfinished argument about Russia.

In 1954, the Soviet Presidium voted to transfer Crimea from Russia to Ukraine. The session lasted minutes. The consequences are still running.
