Легницкое княжество
Like his brothers Wenceslaus II and Henry VIII, Bolesław IV was destined to the Church since his early years, in order to prevent further divisions of the already small Duchy of Legnica. In addition, on 2 December 1372 the brothers signed an agreement which declared the indivisibility of the duchy for the next ten years. This agreement, who was gradually extended in the subsequent years, left Bolesław IV and his brothers (who were all co-rulers of Legnica) without any real power or decision in the government, who was taken totally by the elder brother Rupert I.
