Andrija Torkvat Brlić, descendant of eminent Brlić family, a lawyer, politician, linguist and a publicist, throughout his life managed to leave a significant contribution in many areas of cultural and social life of Croatia in nineteenth century. After his primary education in his home town Slavonski Brod and his gymnasium education in Vinkovci, he proceeded his education in monastery in Zagreb where he met the leading persons of Croatian cultural and public scene and got familiar with ideas of Croatian national revival. During the revolutionary events in 1848. he turned to politics supporting governor Josip Jelačić, the idea of Slavic collectivness, and reorganization of Habsbourg Monarchy in federative union of equal nations. During the second half of nineteenth century in Croatia the most of linguistic dispute were those between Zagrebian philological school and Croatian followers of Vuk Stefanović Karadţić. Observing from linguistic point of view, Andrija Torkvat Brlić left a significant contribution to Croatian language with his grammar of Croatian language written in German Grammatik der iliyrischen Sprache from 1854 for which he was often classified as one of the first followers of Vuk Stefanović Karadţić along with Tomo Maretić, Pero Budmani and Mirko Divković by Croatioan linguists. But, with more detailed inquiry in features of linguistic norm of followers of Vuk Stefanović Karadţić and of Illyrian, present in his grammar, it is shown that Andrija Torkvat Brlić can not be uniquely classified as a Croatian follower of Vuk Stefanović Karadţić and that his grammar contains different linguistic norms.
