"Frederick II (German: Friedrich II.; 24 January 1712 – 17 August 1786) was King in Prussia from 1740 until 1772, and King of Prussia from 1772 until his death. His most significant accomplishments include his military successes in the Silesian wars, his re-organisation of the Prussian Army, the First Partition of Poland, and his patronage of the arts and the Enlightenment. Frederick was the last Hohenzollern monarch titled King in Prussia and declared himself King of Prussia after annexing Polish Prussia from the Polish–Lithuanian Commonwealth in 1772. Prussia greatly increased its territories and became a major military power in Europe under his rule. He became known as Frederick the Great (German: Friedrich der Große) and was nicknamed "The Old Fritz" (German: "Der Alte Fritz")." - (en.wikipedia.org 15.02.2022)
