An entry in an expert encyclopedia about the preliminary Treaty of Breslau between Austria and Prussia. Prussia gained full souverenity over Upper and Lower Silesia and Breslau “for all enternity”. Both sides gave up all mutual claims and promised to sign the final peace treaty within four weeks. Frederick the Great promised to maintain the position of the Catholic church in Silesia; he pledged to exit the anti-Austrian coalition and to assume the debt to Great Britain tied to Silesia in the amount of 1,7 million gulden.
