Friedrich der Große Biography (Wikipedia)
Frederick II (German: Friedrich; 24 January 1712 – 17 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 and his final success against great odds in the Seven Years' War. Frederick was the last Hohenzollern monarch titled King in Prussia and declared himself King of Prussia after achieving sovereignty over most historically Prussian lands in 1772. 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 nicknamed Der Alte Fritz ("The Old Fritz") by the Prussian people and eventually the rest of Germany.
In his youth, Frederick was more interested in music and philosophy than the art of war. Nonetheless, upon ascending to the Prussian throne he attacked Austria and claimed Silesia during the Silesian Wars, winning military acclaim for himself and Prussia. Toward the end of his reign, Frederick physically connected most of his realm by acquiring Polish territories in the First Partition of Poland. He was an influential military theorist whose analysis emerged from his extensive personal battlefield experience and covered issues of strategy, tactics, mobility and logistics.
