Nikola Šubić Zrinski, also commonly known as Nikola IV Zrinski or Miklós IV Zrínyi was a Croatian nobleman and general, Ban of Croatia from 1542 until 1556, royal master of the treasury from 1557 until 1566, and a descendant of the Croatian noble families Zrinski and Kurjaković. During his lifetime the Zrinski family became the most powerful noble family in the Kingdom of Croatia.
Zrinski became well known across Europe for his involvement in the siege of Szigetvár, where he heroically died stopping Ottoman Empire's Sultan Suleiman the Magnificent's advance towards Vienna. The importance of the battle was considered so great that the French clergyman and statesman Cardinal Richelieu described it as "the battle that saved civilization". Zrinski became considered a role model of a faithful and sacrificial warrior, Christian hero as well as a national hero in both Croatia and Hungary, and is often portrayed in artworks.
