Among those killed were children and bystanders. Bloody Sunday is the birth of the first Russian revolution.

Workers' strikes.

Following the events of January 9, strikes spread across the country. The peasants rose against the authorities and began to destroy the houses of their landlords. University professors and teachers joined them. All social classes rose against the police.

Unions.

Because the authorities were rigid about attitudes, people organized unions. On May, 14 different associations joined this association. The unions were led by intellectuals, among whom Pavel Milyukov stood out. Over time, these alliances/unions began to form throughout Russia.
