Serbian politician, writer, lawyer and convicted war criminal. He is the founder and president of the nationalist Serbian Radical Party. From 1998 to 2000, he was Deputy Prime Minister of Serbia.
He voluntarily surrendered to the International Criminal Tribunal for the former Yugoslavia (ICTY) in February 2003 but his trial did not begin until November 2007. After spending 11 years in detention in the United Nations Detention Unit of Scheveningen during his trial, Šešelj was permitted to temporarily return to Serbia in November 2014 to undergo cancer treatment. He led the SRS in the 2016 elections, and his party won 23 seats in the parliament.
On 31 March 2016, he was acquitted in a first-instance verdict on all counts by the ICTY pending appeal. The acquittal was appealed by prosecutors from the MICT, a United Nations Security Council agency which functions as oversight program of, and successor entity to, the ICTY. In the 2018 Appeal, he was sentenced to 10 years for crimes against humanity. He stays out of prison, as he has already served longer than this latest sentence demands.
The crimes in the indictment include, among others, that Šešelj, both individually and as part of a “joint criminal enterprise”, engaged in “the permanent forcible removal of a majority of the Croat, Muslim and other non Serb populations from approximately one-third of the territory of the Republic of Croatia (“Croatia”), and large parts of Bosnia and Herzegovina, and from parts of Vojvodina, in the Republic of Serbia (“Serbia”), in order to make these areas part of a new Serb-dominated state”.
Šešelj authored close to 200 books, mostly in the form of (court) documents and transcripts from interviews and public appearances. Some of the book titles are formulated as insults to his enemies, ICTY judges and prosecutors, and domestic and foreign political figures.
