Jovan Ruvarac was born at
Sremska Mitrovica on 1 September 1832 to Reverend Vasilije Ruvarac (1803–1873) and his wife Julijana, née Šević. He had three brothers, Lazar,
Kosta and
Dimitrije. Lazar Ruvanac became an official in the Serbian government, Kosta Ruvarac (1837–1864) was a writer and literary critic who died while still a student at a university in Pest, and Dimitrije Ruvarac (1842–1933) was a historian and Orthodox clergyman. The Ruvarac family settled in
Syrmia in
Austria-Hungary, today's
Serbia, from the region between
Bihać and
Cazin, nowadays
Bosnia and Herzegovina, then
Ottoman Empire. His childhood was spent at
Stari Slankamen and
Stari Banovci in
Srem, where he went to grammar school. His family then moved to Karlovci and later to Vienna, where he completed his high school education at the
Gymnasium of Karlovci and a gymnasium in
Vienna before enrolling at the
University of Vienna's School of Law in 1852. At the same time, he studied history; a passion of his going back to high school days when he was inspired by one of his professors
Jakov Gerčić. While a student in Vienna, Ruvarac became involved with a social circle of prominent South Slavic intellectuals, such as the philologists
Vuk Karadžić and
Đuro Daničić, who gathered at the famous café
Slavisches Kafeehaus. During his studies, Ruvarac attended lectures by the Austrian historian
Albert Jäger. He was also inspired by the works of
Friedrich Christoph Schlosser,
Georg Gottfried Gervinus and most notably
Leopold von Ranke. Ruvarac took Ranke's principle of objectivity to history as the basis for his research. After graduating with a law degree in 1856, he enrolled at the
Theological Seminary of Saint Arsenius (Sveti Arsenije) in Sremski Karlovci, graduating in 1859. Upon completing his studies in law, history, and theology, he decided to take holy orders and the new name of Ilarion on the date of his tonsure at
Krušedol monastery on 1 January 1861. Under his new name (Ilarion), he published numerous historical studies that he had written up until then. He was then appointed clerk of the Serbian Orthodox Ecclesiastical Court at Karlovci. In 1872 he became a member of the teaching staff at the Gymnasium of Karlovci, his Alma mater. He was elevated to the rank of
Archimandrite at the
Monastery of Grgeteg in 1874. ==Historiography==
