Title: Count Palatine Joseph Charles of Sulzbach
Content:  Joseph Charles, Hereditary Prince of Sulzbach (German: Joseph Karl; Sulzbach, 2 November 1694 &ndash; Oggersheim, 18 July 1729) was the eldest son of Theodore Eustace, Count Palatine of Sulzbach.
Title: Count Palatine Joseph Charles of Sulzbach
Content:  The Sulzbach line was related to the Palatinate-Neuburg line who were Electors Palatine. The Elector of the Palatinate Charles III Philip failed to produce a legitimate male heir, as did his brothers. Joseph Charles, the eldest son of the Count Palatine of Sulzbach, was the heir apparent. On 2 May 1717 Joseph Charles married Countess Palatine Elizabeth Augusta Sophie of Neuburg (1693–1728), the daughter of Charles III Philip, a match intended to unite the two lines and prevented another succession war. However, all the sons fathered by the couple died in infancy and only three daughters survived. In 1728 Elizabeth Augusta died in childbirth and Joseph Charles died the following year in Oggersheim. Therefore, the inheritance of Palatinate-Sulzbach and the eventual inheritance passed to Joseph Charles' brother John Christian Joseph and his family. Joseph Charles was buried in the St. Michael's Church, Munich.

In 1732 he succeeded his father as Count Palatine of Sulzbach, but died in Sulzbach in 1733 before inheriting the Palatinate.

Title: Palatinate-Sulzbach
Content:  In 1614 Palatinate-Sulzbach was partitioned from Palatinate-Neuburg following the death of Count Palatine Philip Louis for his son Augustus. It consisted of two noncontiguous areas separated by the Electorate of Bavaria. It was bordered on the west by the territory of the Imperial city of Nuremberg and on the east by the Kingdom of Bohemia. Augustus' successor Christian Augustus was a tolerant ruler who allowed his subjects to choose their religious denomination, introduced the simultaneum, allowed Jews to live in Sulzbach in 1666, and established an important printing industry. It became clear during the reigns of his successors that Palatinate-Sulzbach would inherit the Electorate of the Palatinate following the death of Charles III Philip, but this would only occur in 1742 for Charles Theodore.
