The club was founded on 27 May 1908 with the intention to stimulate the soccer-activities in Anderlecht. The club was named Sporting Club Anderlecht, but because of the 25th anniversary the word Royal was added. Thus Royal Sporting Club Anderlecht, or shortly RSCA.
The club played its first games on a field that could hardly be called a football ground. The name of the field was "Scheut". Yet the Mauves won their first practice-matches and therefore they decided to enter the club in the league. Anderlecht started in the third regional division.
RSCA performed already well in the first year and in 1912 Anderlecht promoted, with Theo Verbeeck on the team, to the national divisions. Through the successes the club moved in 1917 to the Meirpark, now known as the Astridpark.
On 16 April 1921 Anderlecht pushed through for the first time to the highest division! There were still some degradations, but after the season 1934-1935 the club stayed for good in the first division. And also there the successes didn't stay away long. In 1947 Anderlecht played for the first time champion. This was the first of many titles Anderlecht would obtain.
Also the European successes didn't stay away. Anderlecht won, under the leadership of Pierre Sinibaldi, Anderlecht won 5 titles in a row. In the seventies, the Europa Cup II was won twice. In 1976 it beated West Ham in the finals and in 1978 it won against Austria Wien. In 1977 and 1990 the mauve and whites also lost two finals. Anderlecht won for the first time the UEFA cup against Benfica in 1983. In 1976 and 1978 RSCA won the European supercup against Bayern München and Liverpool.
Also in the year 2000 Anderlecht performed well. They caught their 25th title, they won the Belgian Supercup and obtained a qualification for the Champions League... Seventeen years later, the number already added up to 35 titles.
In the year 2018, the club was sold in the middle of the season, bringing an end to the Vanden Stock rule over the club. The new owner became, surprisingly, entrepreneur and billionaire Marc Coucke, who immediately started the modernisation process of the club. With his new owner, the ambitions are higher than ever for Anderlecht!
