He received his education during the First Serbian Uprising at the newly established grandes écoles founded by Ivan Jugović (Jovan Savić).
While in exile, he maintained connections with prominent insurgent leaders such as Karađorđe, Luka Lazarević, Vule Ilić, Janićije Đurić, Sava Filipović, and others.
He drew from a wide range of sources, including official documents, original materials related to the uprising, correspondence with contemporaries, and narrative accounts from leaders and participants.
[2] His book, "History of the Serbian Uprising" (Istorija srpskog ustanka),[3] is considered one of the most comprehensive first-hand accounts of the revolution that took place from 1803 to 1813.
The work offers a thorough analysis of the events leading to the restoration of the Serbian state after nearly 350 years under Ottoman rule, which began with the fall of Smederevo Fortress in 1459.
