Belgium is one of the Founding Seven Eurovision nations, participating in the first contest in 1956. The selection of their entries alternates each year between the Flemish broadcaster VRT (formerly BRT) and the Wallonian broadcaster RTBF.
They have been absent only three times due to relegation, and in 1962 was the very first country to fall victim to the ever-dreaded Nul Points - shared with three other countries but was the first due to an earlier draw in the running order. They also won once in 1986 thanks to Sandra Kim and hosted the contest in Brussels the following year. The country holds a record for the youngest winner, as Sandra Kim was 13 at the time of the contest, and as of 1990, all people on the stage (including dancers) have to be at least 16 years of age. It also made Belgium the last of the original seven countries to get their first win.
Their 1993 entrant, Barbara Dex, inspired the website "eurovisionhouse.nl" to introduce the Barbara Dex Award, where fans vote for the worst-dressed performer at the contest, after wearing an unattractive handmade dress.
Since the introduction of the semi-finals, Belgium has only been able to make the final six times: 2004 (thanks to Urban Trad's second-place finish in Riga), 2010, 2013, 2015, 2016 and 2017.
2021 was supposed to be RTBF's year to select the Belgian entry, however due to the cancellation of the 2020 contest they agreed to carry over the intended artist selected by VRT.
