Delnice was first mentioned in the year 1482. The first settlement was Chakavian, situated somewhere south of Lučice. The Turkish attacks happening in Gorski Kotar at the time affected Delnice. The people that survived the attacks had to relocate to Kranjska, Slovenia. Only a small part of the population stayed on the spatial valleys near Kupa. After the town started to recover from the attacks, at the beginning of the 17th century, the Zrinski family settled in Delnice. The reconstruction of Delnice and the whole of Gorski Kotar was stopped after the failed Zrinski - Frankopan massacre in 1670. The same year, Austrian General, Ivan Josip Herberstein, robbed Gorski Kotar, and the great Zrinski lands came under the rule of Vienna. The construction of the Karolina road started to bring back the population and revenue, and Delnice began to slowly take back control of their city. This was solidified by the completion of the Louisiana road in 1811, making Delnice the center of Gorski Kotar once again. Industries in Delnice started booming, including the processing of wood, agriculture, cattle breeding, and small entrepreneurship.
