Archduke Leopold Wilhelm of Austria (5 January 1614 – 20 November 1662), younger brother of Emperor Ferdinand III, was an Austrian soldier, administrator and patron of the arts. He held a number of military commands, with limited success, and served as Governor of the Spanish Netherlands, before returning to Vienna in 1656. Despite being nominated as Holy Roman Emperor after Ferdinand's death in 1657, he stood aside in favour of his nephew Leopold I. His main interest was in art, and he patronised artists including David Teniers the Younger, Frans Snyders, Peter Snayers, Daniel Seghers, Peter Franchoys, Frans Wouters, Jan van den Hoecke and Pieter Thijs. His collection of 17th century Venetian and Dutch paintings are now held by the Kunsthistorisches Museum in Vienna. Life Born at Wiener Neustadt on 5 January, 1614, he was the sixth of seven children born to Emperor Ferdinand II (1578-1637) and his first wife, Maria Anna of Bavaria (1574–1616). His elder brother became Emperor Ferdinand III (1608–1657). Career As a younger son, Leopold was educated for the church but was never ordained. Despite not being a member of the clergy, he held various Prince-Bishoprics within the Holy Roman Empire to provide him an income: Halberstadt (1628–1648), Passau (1625–1662), Breslau (1656–1662), Olmütz (1637–1662) and Strasbourg (1626–1662). He was also appointed to the Bishopric of Halberstadt in 1627, Magdeburg in 1629 and Bremen in 1635. All three were in the Protestant north, where the infrastructure of the Catholic church had long since disappeared; he never exercised power and all three were secularised in 1648. He became the Grand Master of the Teutonic Order in 1641. During his lifetime, the Habsburg rulers of Spain and the Holy Roman Empire faced the 1568 to 1648 Dutch Revolt, the 1618 to 1648 Thirty Years War and other conflicts, including the Franco-Spanish War (1635–1659). Despite his reluctance, Ferdinand made him Imperial commander in 1639, largely due to lack of reliable subordinates; he resigned following a disastrous defeat at Second Breitenfeld in 1642, a battle fought against the advice of his generals. He was re-appointed after another Imperial defeat at the 1645 Battle of Jankau, then Governor of the Spanish Netherlands in 1647. In that role, he helped negotiate an end to the war in the 1648 Treaty of Westphalia; the Franco-Spanish war continued, obliging him to remain in Brussels until 1656.
