Frederick II (German: Friedrich II.; 24 January 1712 – 17 August 1786) was a King in Prussia (1740–1772) and a King of Prussia (1772–1786) from the Hohenzollern dynasty. In his role as a prince-elector of the Holy Roman Empire, he was also Elector of Brandenburg. He was in personal union the sovereign prince of the Principality of Neuchâtel. He became known as Frederick the Great (Friedrich der Große) and was nicknamed Der Alte Fritz ("Old Fritz").
Interested primarily in music and philosophy and not the arts of war during his youth, Frederick unsuccessfully attempted to flee from his authoritarian father, Frederick William I, with childhood friend Hans Hermann von Katte, whose execution he was forced to watch after they had been captured. Upon ascending to the Prussian throne, he attacked Austria and claimed Silesia during the Silesian Wars, winning military acclaim for himself and Prussia. Near the end of his life, Frederick physically connected most of his realm by conquering Polish territories in the First Partition of Poland.
Frederick was a proponent of enlightened absolutism. For years he was a correspondent of Voltaire, with whom the king had an intimate, if turbulent, friendship. He modernized the Prussian bureaucracy and civil service and promoted religious tolerance throughout his realm. Frederick patronized the arts and philosophers, and wrote flute music. Frederick is buried at his favorite residence, Sanssouci in Potsdam. Because he died childless, Frederick was succeeded by his nephew, Frederick William II of Prussia, son of his brother, Prince Augustus William of Prussia.

Pro Gloria et Patria (lat. „Für Ruhm und Vaterland“) war der Wahlspruch auf den Truppenfahnen der Preußischen Armee.
1713 legte Friedrich Wilhelm I. von Preußen als erster deutscher Monarch einheitliche Maße und Motive für Fahnen und Standarten seiner Truppen fest.
Die Mitte der Regimentsfahnen und Standarten nahm der preußische Adler ein in einem Lorbeerkranz mit Krone, über diesem schwebte zunächst ein Spruchband mit dem Motto Non Soli Cedit (lat. „Er weicht nicht vor der Sonne.“). Unter Friedrich II. wurde dieses gegen Frankreich und dessen Sonnenkönig Ludwig XIV. gerichtete Motto in Pro Gloria et Patria geändert. Diese Version der Truppenfahne wurde bis 1918 verwendet.
Bis 1945 verwendeten die in die Wehrmacht übernommenen Einheiten der Preußischen Polizei und Ordnungspolizei ebenfalls ein Truppenfahne nach Preußischem Muster mit dem Wahlspruch.
