The Treaty of Breslau was a preliminary peace agreement signed on 11 June 1742 following long negotiations at the Silesian capital Wrocław (German: "Breslau" ) by emissaries of Archduchess Maria Theresa of Austria and King Frederick II of Prussia ending the First Silesian War. Using only the above description and what you know about the world, "The Treaty of Breslau marked the ending of the  First Silesian War." is definitely correct, incorrect, or inconclusive?
