Luxembourg was one of the countries that participated in the first Eurovision Song Contest in 1956. From their debut to 1993, Luxembourg competed frequently in the Contest, being absent from the contest once during this period. They also developed themselves as a powerhouse in the contest, winning it five times, with Tu te reconnaîtras holding the record for the highest percentage of possible points scored.
However, since being relegated from taking part in the 1994 contest the country withdrew from the contest indefinitely after a run of bad placings in the late 1980s and early 1990s.
In 2016, Luxembourg equaled the record of 24 consecutive non participations set by Monaco. Their reasons for not joining includes financial issues, a focus on news-based programming rather than entertainment, and the perception that smaller countries would not be able to succeed in the current contest.
When scoring changed to the 12-point system in 1975, Luxembourg got the honor of being the very first recipient of the "douze points", receiving it from the Netherlands.
On 12 May 2023, it was announced that the country would return to the contest in 2024. That year Luxembourg qualified to the final, which means it is one of two countries with a perfect qualification score, the other being Ukraine.
