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.

[1] 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.

[2] Jovan Hadžić is remembered as a founder of the Matica Srpska and as the most persistent opponent of Vuk Karadžić's orthographic reform.

Hadžić arrived in Serbia in 1837, as one of the leading lawyers he was a prominent figure in public life, a participant in political struggles, and an opponent of Prince Miloš Obrenović.

He worked on the structure of the Supreme Court of the Principality of Serbia but did not manage to complete the Code of Judicial Procedure.

He helped the then gifted high school student Svetozar Miletić to receive a scholarship of 100 pounds from Bishop Josif Rajačić.

Hadžić is considered to be Karadžić's greatest opponent, but in 1866 he allowed himself to be taught according to Vuk's and Đura Daničić's spelling, and Old Slavonic according to Miklošić, at the Great Serbian Gymnasium in Novi Sad, where he was the school principal later in life.

As a poet, he is at the crossroads of the old classicism of Lukijan Mušicki towards newer poetic aspirations whose stimuli came from German literature and our folk poetry.

Following the example of his teacher, Hadžić wrote an ode to the glory of prominent contemporaries, patriotic, didactic songs, and showed great interest in political and epic poetry.

He translated works of the ancient and modern classical tradition: Homer, Virgil, Horace, Friedrich Schiller, Goethe, and many others.

However, the justification for such an attitude of Hadzic can be found in the influence that his schooling in Habsburg monarchy had on him, but that does not justify him on the philological level.

His literary work is, of course, very important in the Serbian literature of the 19th century, but his conservative ideas, which disrupted the attempts to advance in the language at the time, were the ones that somewhat prevented his success in philology.

Jovan Hadžić died in April 1869 and was buried in Novi Sad, in front of the gate of the St. John's Church, where his widow erected a monument to him.
