with the Pomeranian dukes (see below). In 1473 the town was briefly captured by Bogislaw X, Duke of Pomerania. Modern era In the 16th century, Margrave Johann of Brandenburg-Küstrin converted the Neumark to Protestantism, seceded from Brandenburg and transferred his court from Soldin to Küstrin (now Kostrzyn nad Odrą, Poland). The Dominican monastery was dissolved. Soldin suffered heavy damage in the Thirty Years War, when it was overrun by the Imperial army under Albrecht von Wallenstein marching against King Christian IV of Denmark. It began to recover only in the 18th century as a garrison town of the Kingdom of Prussia under Frederick the Great. When the German Empire was formed in 1871, Soldin was the capital of a rural district (Landkreis) within the Prussian Province of Brandenburg. In the 19th century, Soldin was largely bypassed by the industrial revolution, and was not served by rail until 1888. Electrification came in 1898, and a municipal water system only in 1912. In the nearby forest, the Lituanica plane crash occurred on 17 July 1933. By the beginning of the Second World War in 1939, Soldin had 6,284 inhabitants. The city was captured without a fight by the Red Army on 31 January 1945. After a Soviet soldier attempting to rape a local woman was shot and killed by her husband on 3 February, the Soviets rounded up 160 civilians from the town, mostly teenaged boys and elderly men, and murdered 120 of them in a nearby quarry four days later. After the discovery of the mass grave of the victims in 1995, a memorial commemorating the victims was erected. With the end of the war in 1945, the partly depopulated area was transferred to Poland under border changes promulgated at the Potsdam Conference. The surviving German population of Soldin was forcibly expelled and the town, renamed Myślibórz, was gradually repopulated by Polish settlers. It was a powiat centre initially in Szczecin Voivodeship (1945-1975), then in Gorzów one (1975-1998), finally in West Pomeranian one since 31 December 1998. Historically, the town was the site of two important treaties: The Treaty of Soldin (1309) between the Margraviate of Brandenburg and the Teutonic Order State, and the Treaty of Soldin (1466) between the Electorate of Brandenburg and the Duchy of Pomerania.
