Philip Hyacinth of Lobkowicz

Phillip Hyacinth von Lobkowicz (25 May 1680 – 21 December 1734) was the 4th Prince of Lobkowicz, Duke of Sagan, owner of the Princely county of Störnstein and other possessions in the Upper Palatinate, in Silesia and in Bohemia.

Early life Lobkowicz was born on 25 May 1680 in Neustadt an der Waldnaab in Bavaria. He was the eldest son of Ferdinand August von Lobkowicz (in turn eldest son of Václav Eusebius František of Lobkowicz) and, his first wife, Claudia Franziska von Nassau-Hadamar (1660–1680), a daughter of Maurice Henry, Prince of Nassau-Hadamar and Ernestine Charlotte von Nassau-Siegen (the daughter of Count John VIII of Nassau-Siegen).

Musical patronage Like his father, he was a friend and supporter of lute music and an active lutenist, composing several works for the lute. He also contributed important works to the Roudnice Lobkowicz Library.

One of his friends at the Viennese court was the lutenist Silvius Leopold Weiss. Christoph Willibald Gluck's father was a forester in the service of Phillip Hyacinth in Jezeří. During his time in Vienna, Phillip Hyacinth supported Gluck from 1729 onwards. With Phillip Hyacinth's stepbrother, Georg Christian of Lobkowicz, he travelled through Europe, which took him to London. Gluck dedicated operas La Sofonisba (1744), Ipermestra (1745) and a pasticcio (1743) to him. Phillip Hyacinth founded what was then an important band for the Loreta monastery in Prague.

Ferdinand von Lobkowicz (d. 1704), who died young.

After the death of his first wife, he married Countess Maria Wilhelmine von Althann (1704–1757) on 25 August 1721. She was a cousin of Count Gundaker Ludwig von Althann. Together, they were the parents of:

Wenzel Ferdinand, 5th Prince of Lobkowicz (1723–1739), who died unmarried. Ferdinand Philipp Joseph, 6th Prince of Lobkowicz (1724–1784), who married Princess Maria Gabriella di Savoia-Carignano, a daughter of Louis Victor, Prince of Carignano and Princess Christine of Hesse-Rotenburg (daughter of Ernst II Leopold, Landgrave of Hesse-Rotenburg), in 1769. Marie Anne von Lobkowicz (1725–1729), who died young. Anne Maria Elisabeth von Lobkowicz (1726–1786), who married diplomat Count Anton Corfiz von Ulfeldt, in 1743.

The Prince of Lobkowicz died on 21 December 1734 in Vienna and was succeeded by his eldest surviving son, Wenzel Ferdinand. He died, unmarried, in 1739 and the title passed to his younger brother, Ferdinand.
