Serbia and Montenegro existed
between 2003 and 2006. The two republics, both of which are former
republics of the SFR Yugoslavia, initially formed the Federal Republic
of Yugoslavia in 1992. In 2003, the FRY was reconstituted as a State
Union of Serbia and Montenegro.
On 21 May 2006, Montenegro held a referendum to
seek full independence. The state union effectively came to an end after
Montenegro's formal declaration of independence on 3 June 2006 and
Serbia's formal declaration of independence on 5 June.
