His commitment to liberal ideals often placed him at odds with the absolutist regime of Prince Mihailo Obrenović, leading to multiple imprisonments, though public support frequently secured his release.

[3] The family patriarch, Grujića Šestanović, played a notable role in both Serbian insurrections and served as a deputy in the assembly during Prince Miloš Obrenović’s first reign.

He criticised the church, praised education, and expressed faith in progress, while lamenting Serbia's lack of internal and external freedom as a vassal of the Ottoman Empire without constitutional rights.

Known as one of the "Parisians", a group of young liberals influenced by French political thought, Grujić joined the civil service, steadily rising through its ranks.

[11][12] Jevrem Grujić emerged as a significant figure in Serbian politics during the St Andrew's Day Assembly (Svetoandrejska skupština) of 1858, which led to the overthrow of Prince Alexander Karađorđević.

Dr Slavko Grujić earned his doctorate at the Sorbonne in Paris and held prominent roles as Serbian Undersecretary for Foreign Affairs and diplomat, serving in Athens, Petrograd, Washington, and London, where he died.

[20] He married the American Mabel Dunlop Grujić, who significantly contributed to humanitarian efforts by raising funds and establishing aid initiatives for Serbian soldiers fighting on the Salonika front.

Through the efforts of Slavko and Mabel Grujić, the Belgrade University Library “Svetozar Marković” was built, funded by a $100,000 donation from the Carnegie Endowment for International Peace.
