Count Ferenc Nádasdy III (1623-1671) was a member of one of the most prominent Hungarian aristocratic families. He entered history as the leader of a conspiracy against the Habsburg Emperor Leopold I. The plot was discovered and he was sentenced to death: on April 30, 1671, he was beheaded in Vienna. Until his death he had extensive estates in the Prekmurje Region. After his death the estate was taken over by the Hungarian Royal Chamber.
