In September 1877, he enrolled in the grammar school in Požun (today's Bratislava). Joca Vujić wrote in his diaries about the influence this city left on him: "Požun has left a mark on my future life. There I learned about cultural, sober civic life, there I saw how people live in German civic families, there was no family life at all at our house in Senta. In Požun, I got the will to collect antiquities and the love for antiquities and the past, that Požun is in itself a museum of antiquities. In Požuna, my excessive Serbian nationalism developed in me, my love for Serbia and my unspoken aspiration to work and use all my strength for the cultural progress of my backward Serbia in every way". The awakening of nationalism in Joca was also influenced by important historical events of this period, such as the Nevesinje Uprising, the Serbian-Turkish War and the Russian-Turkish War.
