Context paragraphs:
Second Silesian War: The Second Silesian War was a theatre of the War of the Austrian Succession.  The name is used to describe Prussia's war against Austria between 1744 and 1745, fought mainly in Silesia, Bohemia, and Upper Saxony.  It was the second in a series of three Silesian Wars fought between Frederick the Great's Prussia and Maria Theresa's Austria.

First Silesian War: The First Silesian War was a theatre of the War of the Austrian Succession.  The name is used to describe Prussia's war against Austria between 1740 and 1742, fought mainly in Silesia, Moravia and Bohemia (the lands of the Bohemian Crown).  It became the first in a series of three Silesian Wars fought between Frederick the Great's Prussia and Maria Theresa's Austria.

Battle of Mollwitz: The Battle of Mollwitz was fought by Prussia and Austria on 10 April 1741, during the First Silesian War (in the early stages of the War of the Austrian Succession).  It was the first battle of the new Prussian King Frederick II, in which both sides made numerous military blunders but Frederick the Great still managed to attain victory.  This battle cemented his authority over the newly conquered territory of Silesia and gave him valuable military experience.

Battle of Chotusitz: The Battle of Chotusitz, or Chotusice, sometimes called the Battle of Czaslau, was fought on May 17, 1742, in Bohemia between the Austrians under Prince Charles Alexander of Lorraine and the Prussians under Frederick the Great.  The battle was a part of the War of the Austrian Succession, sometimes referred to as the First Silesian War.  The armies were about equal at 28,000 to 30,000 each, with the Prussians having about 2,000 more infantry and the Austrians some 2,000 more cavalry.  The Austrians were attempting to retake occupied Prague and the Prussians were trying to block them from accomplishing that.  The battle of Chotusitz was especially notable in that it was the only major battle started by the Austrians during this war.

Treaty of Breslau: 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.

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.

Silesian Wars: The Silesian Wars (German: "Schlesische Kriege" ) were a series of three wars fought in the mid-18th century between Prussia (under King Frederick the Great) and Austria (under Empress Maria Theresa) for control of Silesia, all three of which ended in Prussian victory.  The First (1740–42) and Second (1744–45) Silesian Wars formed a part of the larger War of the Austrian Succession, while the Third Silesian War (1756–63) was one theater of the Seven Years' War.

Frederick the Great: Frederick II (German: "Friedrich" ; 24 January 171217 August 1786) was King of Prussia from 1740 until 1786, the longest reign of any Hohenzollern king.  His most significant accomplishments during his reign included his military victories, his reorganization of Prussian armies, his patronage of the arts and the Enlightenment in Prussia, and his final success against great odds in the Seven Years' War.  Frederick was the last titled King in Prussia and declared himself King of Prussia after achieving full sovereignty for all historical Prussian lands.  Prussia had greatly increased its territories and became a leading military power in Europe under his rule.  He became known as Frederick the Great ("Friedrich der Große ") and was affectionately nicknamed "Der Alte Fritz " ("Old Fritz") by the Prussian and later by all German people.

Third Silesian War: The Third Silesian War was a theatre of the Seven Years' War.  The name is used to describe Prussia's war against Austria and its allies between 1756 and 1763, fought mainly in Silesia, Bohemia and Upper Saxony.  The war was the third and last in a series of Silesian Wars fought between Frederick the Great's Prussia and Maria Theresa's Austria; like the earlier two, it ended with Prussia in control of the region of Silesia.

Treaty of Hubertusburg: The Treaty of Hubertusburg (German: "Frieden von Hubertusburg" ) was signed on 15 February 1763 at Hubertusburg Castle by Prussia, Austria and Saxony to end the Third Silesian War.  Together with the Treaty of Paris, signed five days earlier, it marked the end of the Seven Years' War.  The treaty ended the continental conflict with no significant changes in prewar borders.  Austria and Saxony renounced all claims to the Silesian territories ceded to Prussia in the 1742 Treaty of Berlin and the 1745 Treaty of Dresden.  Prussia clearly stood among the ranks of the European great powers, while the treaty enhanced the rivalry with Austria.
