Views
Przemysław II was deposed in 1476 and half of both Głogów and Ścinawa were annexed to the Bohemian crown. However, Margareta remained in Głogów and defended the city from the ambitions of January II the Mad, Duke of Żagań, who, after a siege of seven weeks, on 1 May 1480 conquered the city and reunited the whole Duchy of Głogów after almost 150 years of separation.
