Nikola Šubić Zrinski ruled as Nicholas IV (1508–1566). He was a hero of the Battle of Szigetvár of the Habsburg-Ottoman wars. Then followed his son, Juraj IV Zrinski (George IV), until 1603, and his grandson Nikola VI. Zrinski (Nicholas VI) until 1624. Next was another grandson, a brother of Nicholas VI, Juraj V Zrinski (George V). He was poisoned in 1626 by the general Albrecht Wallenstein in Pressburg and was buried in Pauline Monastery of Sveta Jelena ("St. Helen" in English) near Čakovec, next to the graves of his ancestors. He was followed by his son Nikola VII Zrinski (Nicholas VII), (1620–1664), a famous Croatian Ban. At the coronation of Ferdinand IV, he carried the sword of state and was made Captain General of Croatia. He was killed while hunting in the forest near Kuršanec (Kursanecz), apparently by a wounded wild boar, but there were rumors that he had been murdered by the order of the Habsburg court. His brother, Petar Zrinski (Peter IV), was noted for his role in the attempted Croatian-Hungarian rebellion of 1664-1670 which ultimately led to his execution for treason. His wife, Katarina Zrinska, died imprisoned for the same offence on 16 November 1673 in Graz. On 19 August 1691 the son of Nicholas VII, Adam Zrinski, fell at Battle of Slankamen while fighting against the Ottoman Empire. Parts of Međimurje remained in the hands of the Zrinski family until the end of the 17th century. The last male member of the family, Ivan Antun Zrinski (John IV), died in prison in 1703.
