What happened
In early March 1921, sailors at the Kronstadt naval base, who had been early and enthusiastic supporters of Soviet power in 1917, rebelled against the Bolshevik government they said had betrayed the revolution's original promises. The mutineers drafted fifteen demands, including free elections to the soviets, freedom of speech and assembly, and equal rations for all workers, alongside an end to the Bolshevik monopoly on power. Lenin and Grigory Zinoviev isolated the island and imposed a press blackout, and Trotsky organized a military response; bombardment of the fortress began on 7 March. Government forces launched three assaults over ten days, taking heavy losses of their own, including troops killed crossing the ice toward the island, before the rebellion was crushed by 18 March. Many surviving rebels escaped across the ice into Finland; others were killed in the fighting or later executed or sent to labor camps.
Why it matters
That sailors who had helped bring the Bolsheviks to power in 1917 were now demanding an end to one-party rule, and were crushed for it, made an unmistakable public statement about how far the regime's practice had diverged from its founding promises. The rebellion, together with the famine and peasant uprisings elsewhere, convinced Lenin within days to abandon War Communism for the New Economic Policy.
How we know
Michigan State University's Seventeen Moments in Soviet History documents the sailors' fifteen demands, the government's bombardment and assault on the fortress, and the fate of the rebels who survived.
