The Battle of Lubieszów (Battle of Lubieszów Lake), which occurred on 17 April 1577, was the most crucial battle in the two-year Danzig Rebellion fought between the forces loyal to the newly elected King Stefan Batory of the Polish–Lithuanian Commonwealth and the Commonwealth's most prosperous city, Gdańsk (Danzig in German), following the city's refusal to accept the election of Batory as monarch of the Commonwealth which had taken place on 15 December 1575. The battle took place to the west of the town of Tczew (Dirschau), southeast of Gdansk on the left bank of the Vistula River, near Lubieszów Lake (present name Lubiszewo Lake) and the modern village of Lubiszewo Tczewskie (German: Lübschau).
