The fourth of the Bogatyr-class cruisers was laid down in 1902 and entered service two years later. As part of the Dobrotvorsky division, the cruiser joined the 2nd Pacific Squadron near Madagascar in the process of her transition to the Far East, where she participated in the Battle of Tsushima. Together with the rest of the division's cruisers, the ship was interned in Manila; later, she returned to the Baltic. During World War I, the cruiser was involved in the operations of the cruiser division of the Baltic Fleet.
