Treaties of Tilsit
In 1806 confederates of Napoleon invaded Silesia. Only the forts of Glatz, Silberberg and Cosel withstood until the Treaties of Tilsit. After the adoption of the reforms of Stein and Hardenberg between 1807 and 1812 Silesia was fully incorporated into Prussia, the Catholic Church properties were secularized and the social and economic conditions improved. At the same time the first European university with both a Protestant and a Catholic faculty was established in Breslau.
