 Križanić was one of the earliest proponents of Pan-Slavism.The language he created and used in his writing was called "Ruski jezik" ("Russian language"), but in reality it was a mixture of several Slavic languages and was devised to serve as a symbol of and even to promote Slavic unity.He wanted to unite the Slavic nations under the Russian Tsar and unite Catholic and Orthodox against the German Protestants and Turkish Muslims.
