Franz III. Nádasdy

Ferenc; 14 January 1622[1] – 30 April 1671) was a chief judge and general in Hungary.

He was one of the leaders of the Magnate conspiracy against Holy Roman Emperor Leopold I.

[2] He was not only descended from a son of Edmund Ironside of England who had settled in Hungary, but was also the grandson of Ferenc Nádasdy.

Nádasdy converted to Roman Catholicism on 25 November 1643 in order to marry Countess Anna Júlia Esterházy (1630–1669), daughter of Nikolaus, Count Esterházy, on 6 February the following year.

[3] After the Hungarian Diet in Pressburg decided upon the return of the County of Hornstein to the Kingdom of Hungary, Nádasdy ordered Rudolf von Stotzingen to dismiss his mercenaries.
