In the quarrel with his elder brother Duke Wenceslaus I of Legnica a 1359 judgement by Emperor Charles IV allotted Lubin along with Krzeczyn Wielki, Krzeczyn Mały, Osiek and Pieszków to Louis. About 1353 he had a manuscript on the life of Saint Hedwig of Andechs drawn up, later called Schlackenwerth (Ostrov) Codex, which today is kept at the J. Paul Getty Museum. In the late 15th century the Lubin parish church was rebuilt in its present-day Gothic style, its high altar was moved to Wrocław Cathedral in 1951.
