Jovan Hadžić (Serbian Cyrillic: Јован Хаџић, pseudonym Miloš Svetić; 8 September 1799 – 28 April 1869) was a Serbian writer, legislator and initiator, that is, the principal co-founder of the Serbian cultural society Matica Srpska. He signed his literary work as Miloš Cvetić and was an influential figure in the drafting of the Civil and Criminal Code of Serbia in 1844. Serbia is the fourth modern-day European country after France, Austria and the Netherlands to have a codified legal system because of Hadžić's work.
