Analysis of information sources in references of the Wikipedia article "Nikola IV Zrinski" in English language version.
One of the richest lords of the region, Nicholas Zrinsky, a Croat whose name took the form of Zrinyi in Hungarian...
...there is no doubt that his mother-tongue was Croat. On the other hand, Croatia at that time had already been an integral part of Hungary for 400 years, albeit under a special administration. As a member of the high nobility, Zrinyi therefore belonged to the natio Hungarica, the political nation of Hungary which, however, was not an ethnic but a juridico-political category. Zrinyi/Zrinski fell as a Croat nobleman in the fight against the Turks for Emperor Ferdinand, who was at the same time crowned King of Royal Hungary. He died as a Croat for Hungary. At that time his ethnic affiliation had nothing to do with language, as it would in modern Hungary.
