Nikolaus Esterhazy

Nikolaus I, Prince Esterházy (Hungarian: Esterházy I. Miklós, German: Nikolaus I. Joseph Fürst Esterhazy; 18 December 1714 – 28 September 1790) was a Hungarian prince, a member of the famous Esterházy family. His building of palaces, extravagant clothing, and taste for opera and other grand musical productions led to his being given the title "the Magnificent". He is remembered as the principal employer of the composer Joseph Haydn.

Nikolaus Esterházy was the son of Prince Joseph (József Simon Antal, 1688–1721), and the younger brother of Prince Paul Anton (Pál Antal, 1711–1762). He took the title of Prince on his brother's death.

His name is given in various languages: German (the lingua franca of the Habsburg Empire) "Nikolaus Josef", Hungarian (probably his native language) "Miklós József," and (in English contexts) the English form of his name, "Nicholas".

In early life he was educated by Jesuits. He became a military officer, serving the Austrian Empire. Of his military career, Robbins Landon notes that he achieved, "considerable distinction, particularly as Colonel at the Battle of Kolin (1757) in the Seven Years' War where, with great personal courage, he led the wavering cavalry troops to victory. He was later made a Lieutenant Field-Marshal."

Robbins Landon narrates Nikolaus's marriage thus: "On 4 March 1737, he married Freiin Marie Elisabeth, daughter of Reichsgraf (Count of the Holy Roman Empire) Ferdinand von Weissenwolf". His son Anton I, Prince Esterházy became the father of Nikolaus II, Prince Esterházy, patron of well known musicians and composers.

During the period before his brother Paul Anton's death, Nikolaus held the title of Count. He generally lived apart from his brother, favoring a hunting lodge near the Neusiedlersee in Hungary. The brothers got along well, however, at least as can be determined from their correspondence.
