The Russian Pillage (Swedish: Rysshärjningarna), is the name for the action of the Imperial Russian Fleet toward the Swedish civilian population along the Swedish east coast, as well as expeditions and the raids of single unit in the inland, during the finishing years of the Great Northern War in 1719–1721. The purpose was to pillage, sack and burn to force the Swedish regime to concessions during the peace negotiations on Åland. The Swedish representative, Georg Heinrich von Görtz, was at the time stalling the negotiations in hope of military support from Great Britain.Peter the Great, on the other hand, wished for a swift end to the war, which would make it possible for him to focus on inner reform.
In the summer of 1719, a Russian fleet consisting of 132 galleys and several smaller boats, totalling 26000 men, assaulted . The Russian fleet pillaged along the coat of Uppland almost as far north as Gävle, and the coast of Södermanland as far south as Norrköping. The archipelago was severely devastated by the assaults. On several of the larger islands, almost all buildings were burnt down. The entire city of Trosa was burnt to the ground, save for the city church and bell tower. After receiving reinforcements, the Russian fleet attempted to attack but were defeated on 12 August 1719.
In 1720, Russian troops razed Umeå, and in 1721 the cities of Hudiksvall, Sundsvall, Söderhamn, Härnösand and Piteå.
