Juraj IV Zrinski,, was a Croatian count, a member of the Zrinski noble family.
Background
He was the son of Croatian Ban (viceroy) Nikola Šubić Zrinski (*1508 - †1566), the hero of Szigetvar, and his wife Katarina Zrinski née Frankopan (married 1543, died 1561), a Croatian countess. From his father he inherited a large number of estates, among which was the Međimurje County, the northernmost part of Croatia, with the large and strongly fortified Čakovec castle. Like his father, he was the main royal treasurer in the Kingdom of Croatia and Hungary.
Career
On the other hand, his contribution was the introduction of book printing into northern Croatia. In the early 70s of the 16th century he invited an Austrian printer and grafic expert named Rudolf Hoffhalter to found a printing office in Nedelišće, a village next to Čakovec. Many publications were printed there in the next couple of years (probably until 1586), among which was the famous juristic book Decretum tripartitum of the publisher Ivanuš Pergošić, the first book ever in Croatian Kajkavian dialect, printed in 1574.
Like his ancestors and descendants, Zrinski took part in battles against the Ottomans, who conquered most of Croatia, and he often carried out the sudden attacks to the hinterland of the enemy in order to slow down or stop them from further conquests.
On May 29, 1579 he granted privileges to the inhabitants of the Čakovec fortress and its suburbs. This was the starting point for Čakovec to become a free market town and the date is celebrated today as Čakovec City Day.
Juraj IV Zrinski was married twice and had four children.
