Treaty of Berlin (1742)

The Treaty of Berlin between the Habsburg archduchess Maria Theresa of Austria, who was also Queen of Bohemia, and the Prussian king Frederick the Great was signed on 28 July 1742 in Berlin. It was the formal peace treaty that confirmed the preliminary agreement achieved with English mediation by the 11 June Treaty of Breslau, and officially ended the First Silesian War.

Based on article 5 of the treaty,

Maria Theresa ceded most of Silesia with the County of Kladsko to Frederick, except for those districts of the Duchy of Troppau that were located south of the Opava river, including the southern part of the former Duchy of Jägerndorf, the possession of which had been one pretext for Frederick's invasion. The Duchy of Neisse held by the Breslau bishops was also partitioned, with the fortress-city of Nysa and the larger northern portion of the territory falling to Prussia. Austria retained the entire Upper Silesian Duchy of Teschen, ruled by Maria Theresa's husband, Francis Stephen of Lorraine, Grand Duke of Tuscany. The remaining Habsburg territories were incorporated into the crown land of Austrian Silesia.

Prussia in turn left the anti-Habsburg coalition it had forged with France, Spain, Sweden, Naples and the Electorates of Bavaria, Saxony and Cologne. It also assumed debts of about 1.7 million gulden which Austria had contracted with her ally Great Britain. King George II of Great Britain acted as guarantor.
