Željko Ražnatović, Serbian commander (d. 2000)
Željko Ražnatović (Serbian Cyrillic: Жељко Ражнатовић, pronounced [ʒêːʎko raʒnâːtoʋitɕ]; 17 April 1952 – 15 January 2000), better known as Arkan (Serbo-Croatian Cyrillic: Аркан), was a Serbian mobster, politician, sports administrator, paramilitary commander and head of the Serb paramilitary force called the Serb Volunteer Guard during the Yugoslav Wars.

He was on Interpol's most wanted list in the 1970s and 1980s for robberies and murders committed in a number of countries across Europe, and was later indicted by the International Criminal Tribunal for the former Yugoslavia for crimes against humanity. Up until his assassination in January 2000, Ražnatović was the most powerful organized crime figure in the Balkans.
