Bloody Sunday in Saint Petersburg
What happened
In 1905, Russian troops fired on peaceful demonstrators in Saint Petersburg who were petitioning Tsar Nicholas II. The massacre shattered popular faith in the tsar as a benevolent ruler. It helped trigger the Russian Revolution of 1905 and destabilised autocracy.
Literary impact
Bloody Sunday deepened Russian poetry's engagement with revolution, martyrdom, and state violence. The crisis formed part of the atmosphere in which Blok, Akhmatova, Mayakovsky, and later Soviet poets confronted the burden of history.
