Serbian Revolution
His other studies, also based on primary sources and available literature in various languages, covered the modern period, prior and during the Serbian revolution (1804–1835): "The Ottoman Empire prior to the Serbian Insurrection, 1780-1804" ("Tursko carstvo pred srpski ustanak 1780-1804"), "The Resurrection of Serbia" ("Vaskrs države srpske") in 1904 (translated into German and published in Sarajevo in 1912), as well as the detailed analysis of first phase of Serbian Revolution ("Ustanak na dahije 1804"). In 1907, equally important was the analysis of the struggle between “supreme and central government” in insurgent Serbia: "The Constitutional Question and the Law under Karageorge" ("Ustavno pitanje i zakon Karadjordjeva vremena").
