music. In 1728, his mother Maria Octavia, "probably at her son's instigation" engaged the composer Gregor Werner to be the family's Kapellmeister (music director), a post in which Werner served for several decades. Much later (1761), Paul Anton engaged Joseph Haydn to be his Vice-Kapellmeister in 1761, taking over most of the aging Werner's duties. At the same time, he upgraded the court orchestra, hiring several virtuosi who served under Haydn; the composer recognized their ability by writing many solo parts in his early symphonies. Prince Nikolaus "the Magnificent" [Miklós József] (1714–1790) Son of Joseph, in his youth a decorated soldier. He was the primary patron of Haydn and builder of Esterháza (see above). Prince Anton [Antal] (1738–1794) Son of Nikolaus I, married first, in 1763, Maria Theresia Gräfin Erdödy e Monyorokerek et Monoszlo (1745–1782), and second, in 1785 Maria Anna Gräfin von Hohenfeld (1768–1848). He was elevated to the status of Prince (Fürst) in 1783. He received the Order of St. Stephen in 1777.

His corps was later absorbed into other military formations. He was Colonel and Proprietor (Inhaber) of the 31st Infantry Regiment, from November 1777 to October 1780, and then Proprietor and Colonel of the 34th Infantry Regiment, from September 1780 until his death. He was initiated to the Order of the Golden Fleece in 1790, and also became an imperial Chamberlain. He disbanded the Esterházy musical establishment for the duration of his reign. Prince Nikolaus II [Miklós Ferdinánd] (1765–1833) Born in Vienna, on 12 December 1765, he was the son of Anton and his first wife Maria Theresia. He became reigning Prince on the death of his father in 1794. Like several of his predecessors Nikolaus II pursued a military career. He is remembered for his amassing a large art collection, for his musical patronage of Haydn and Beethoven, for his sexual debauchery, and for his high expenditures.
