During the Polish–Teutonic War (1326–1332), the city was captured and destroyed by the Teutonic Knights in 1330.[4] Briefly regained by Poland, it was occupied by the Teutonic Knights from 1331 to 1337 and annexed to their monastic state as[citation needed] Bromberg. In 1337, it was recaptured by Poland and was relinquished by the Knights in 1343 at their signing of the Treaty of Kalisz along with Dobrzyń and the remainder of Kuyavia.
