William, Count of Schaumburg-Lippe

He was born in London the son of Albrecht Wolfgang, Count of Schaumburg-Lippe and of his first wife Countess Margarete Gertrud of Oeynhausen (1701–1726), an alleged bastard daughter of George I of Great Britain and his mistress Ehrengard Melusine von der Schulenburg.

He accompanied his father in his campaign in Dutch service during the 1740-1748 War of Austrian Succession, and was present at the Battle of Dettingen (1743). He then fought in Austrian service in their Italian campaign. He succeeded his father as Count on 25 October 1748.

As Count and General of the Artillery (Generalfeldzeugmeister) he sided with Prussia during the Seven Years' War. He distinguished himself at the head of the allied artillery during the Battle of Minden and was rewarded with the overall command of the allied artillery.

Portugal

In 1762, at the request of the Marquis of Pombal (the Portuguese Secretary of State) he led, as Generalissimus, the allied troops in Portugal against the Spanish invasion. William conducted a brilliant defensive campaign of marches and counter-marches, so that the enemy, although it had a three-to-one superiority in numbers, always encountered defenders in a good position and never dared to risk an all-out attack. At the request of Pombal, Lippe stayed on for a year after the peace agreement of 1763.

William's wife Marie Barbara Eleonore

He was also an influential military theorist and an advocate of defensive warfare. One of his best-known slogans is: "Kein anderer als der Defensivkrieg ist rechtmäßig!" ("Only defensive warfare is justified!")

He died at Wölpinghausen and was succeeded by his cousin the count of Lippe-Alverdissen, Philipp II. Ernst. As one of the greatest figures in German history, he is commemorated by a bust in the Walhalla temple.

By 1764 Wilhelm had two children, Joseph and Olimpia Petronellia.[1] They were born in Elvas, Portugal. Olimpia was baptized in the Church "Matriz" in the city of Campo Maior on 24 June 1764. Years after, before her marriage, Olimpia was recognized by her father's cousin, Philip II Ernst, and her name was changed to Olímpia Patronellia Ernestina de Schaumburg-Lippe. Olimpia died on 25 November 1822.

He was married on 12 November 1765 at Stadthagen to Countess Marie Barbara Eleonore of Lippe-Biesterfeld (1744–1776), daughter of Frederick Charles Augustus, Count of Lippe. They had two children; Countess Emilie (1771–1774) and an unnamed son (1772).
