Wrocław

The Duchy of Wrocław was a Lower Silesian Piast territory centred on the Oder city of Wrocław. Its last Piast duke Henry VI died without a son in 1335, and in 1337 King John of Bohemia ruled the duchy directly.

In 1348 Charles IV attached the Silesian duchies to the Bohemian Crown. The Reformation reached Wrocław in 1518, and the Habsburgs inherited Bohemia in 1526. Prussia seized the city, confirmed by the 1742 Treaty of Breslau; its university was refounded under Prussian rule in 1811.
