Jonjić has been writing since 1990.[2] He is a regular member of Matica hrvatska.[5]
Politics
From 2017 and its founding until July 2019, he was a member of the Independents for Croatia party, and a member of its presidency. In the 2017 local elections, he was elected as a representative in the Zagreb City Assembly.[6] During his mandate, Jonjić participated in the work of the five Assembly's committees.[7]
After a split with the party president Bruna Esih, Zlatko Hasanbegović left the party in July 2019 with the majority of the members of the presidency and founded the Bloc for Croatia party,[8] whose presidency included Jonjić, who was also the president of the party's caucus in the Zagreb City Assembly. Before the 2021 local elections, he left the Bloc, "due to different views on national-political issues, elementary ethics and legality".[9]
In February 2024, he rejoined the HSP. He announced his candidacy for the 2024 Croatian presidential election[10] on the cover of Hrvatski tjednik magazine on 23 May 2024.[11] His candidacy was publicly supported by 400 intellectuals.[12][13] On December 10, Jonjić submitted more than 50,000 signatures[13] for his candidacy to the State Election Commission.[14] He won 82,727 (5.09%) of the votes.[15]
