As Serbia was at one time part of Yugoslavia, it had the opportunity to participate in the Eurovision Song Contest after Yugoslavia's debut at the contest in 1961. It debuted the same year as Spain and Finland and became the first and, for three decades, only socialist country to participate in the competition. The best result of Yugoslavia occurred in 1989 when it won with "Rock Me", sung in Serbo-Croatian and English by Riva. Yugoslavia participated regularly until its breakup in 1991/1992.
