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.
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.[1] 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.
When the tomb of Childeric I, an early Merovingian king, was discovered in 1653 by a mason doing repairs in the church of Saint-Brice in Tournai, it was Leopold Wilhelm who had the find published in Latin. On his return to Vienna in 1656, his collection relocated to the Hofburg Palace, where Jan Anton van der Baren, a Flemish priest and artist, served as director. The collection was bequeathed to his nephew Leopold I, and is now part of the collections of the Kunsthistorisches Museum in Vienna.
He played an active role in court politics and was close to his stepmother, Eleonora of Mantua (1598-1655), who shared his interest in Italian art and was a prominent supporter of the Catholic Counter-Reformation. Although suggested as a candidate to replace Ferdinand as Holy Roman Emperor in 1657, he ensured his nephew Leopold I was elected when he reached 18 in July 1658. [3]
