Les Unionistes R Union Saint-Gilloise
Belgium · Founded: 1897
Royale Union Saint-Gilloise is a professional football club from Brussels, Belgium, founded in 1897. It is one of the oldest and historically most successful clubs in Belgian football, playing its home matches at the Joseph Marien Stadium. The club is known for its blue and yellow colors and has deep roots in the capital’s football culture.
Union Saint-Gilloise dominated Belgian football in the early 20th century, winning 11 league titles between 1904 and 1935. During this golden era, the team set a national record by going 60 consecutive league matches unbeaten between 1933 and 1935. After World War II, however, the club declined significantly, eventually falling as low as the fourth tier of Belgian football.
In recent years, the club has experienced a remarkable revival, returning to the top division in 2021 after a 48-year absence. Backed by new ownership, Union quickly became competitive again, consistently challenging for the title and finally winning the Belgian league in 2025, ending a 90-year wait. The club has also re-established itself in European competitions, becoming one of the most notable comeback stories in modern football.
