Some priest Gapon gathered a mob of workers, that were tired of their work conditions, and led them to the Winter Palace Navalny style. The guards tried to stop the mob from advancing but in the crucial moment of hesitation, Gapon proclaimed "Forward, comrades! Freedom or death!" Since there was no tools for mob control outside of bayonets, swords and bullets back then, that was the only way the guards could react. The emperor wasn't even aware of the situation until after it happened.
Gapon was later found out to be a terrorist cell of some socialist revolutionaries and was found dead a year later, murdered by his own.
