Почему Крова́вое воскресе́нье произошедшее 9 (22) января 1905 года в Санкт-Петербурге имеет такое название?
On Sunday, 9 (22) January 1905, Gapon began his march. Locking arms, the workers marched peacefully through the streets. Some carried religious icons and banners, as well as national flags and portraits of the Tsar. As they walked, they sang hymns and "God Save The Tsar". At 2pm all of the converging processions were scheduled to arrive at the Winter Palace. There was no single confrontation with the troops. Throughout the city, at bridges on strategic boulevards, the marchers found their way blocked by lines of infantry, backed by Cossacks and Hussars; and the soldiers opened fire on the crowd.
