Gottfried "Götz" von Berlichingen (1480 – 23 July 1562), also known as Götz of the Iron Hand, was a German (Franconian) Imperial Knight (Reichsritter), mercenary, and poet. He was born around 1480 into the noble family of Berlichingen in modern-day Württemberg. Götz bought Hornberg Castle (Neckarzimmern) in 1517, and lived there until his death in 1562.
He was active in numerous campaigns during a period of 47 years (1498–1544), including the German Peasants' War, besides numerous feuds; in his autobiography he estimates that he fought 15 feuds in his own name, besides many cases where he lent assistance to friends, including feuds against the cities of Cologne, Ulm, Augsburg and the Swabian League, as well as the bishop of Bamberg.
His name became famous as a euphemism for a vulgar expression (Er kann mich im Arsche lecken – "He can lick my ass") attributed to him by writer and poet Johann Wolfgang von Goethe (1749–1832), who wrote a play based on his life.
In 1497, Berlichingen entered the service of Frederick I, Margrave of Brandenburg-Ansbach. In 1498, he fought in the armies of Holy Roman Emperor Maximilian I, seeing action in Burgundy, Lorraine, and the Brabant, and in the Swabian War the following year. By 1500, Berlichingen had left the service of Frederick, and formed a company of mercenaries, selling his services to various Dukes, Margraves, and Barons.
