Żagań

Żagań was a Silesian duchy ruled by a branch of the Piast dynasty. In 1337 Henry IV the Faithful held it as a Bohemian fief, having been forced to accept King John of Luxembourg's overlordship in 1329.

Henry died in 1342 after failing to recover Głogów. His descendants ruled until 1472, when Jan II the Mad sold Żagań to Albert III of Saxony. It passed to the Bohemian Habsburg crown in 1549; Prussia seized it in the First Silesian War, and the Treaty of Breslau confirmed its possession in 1742.
