After some major league reforms, a large number of second division teams had to drop a level.

[7] After a not so successful merge with the team of Harelbeke, a new club was founded to continue the long history of Ingelmunster football.

KFC Mandel United knocked out top-tier club Waasland-Beveren to reach the round of sixteen as one of few teams outside the first division to do so.

[11] Formed through the merger of KFC Izegem and OMS Ingelmunster in 2017, Strive Football Group took a major share in the newly created public limited company in April 2021, changing the name of the club from KFC Mandel United to Royal FC Mandel United.

[12][13][14] KFC Mandel United played its home matches at OMS Ingelmunster Stadion for the 2017–18 and 2018–19 seasons.

[15] Skyline Arena is used by all Royal FC Mandel United Academy teams for all training sessions and games.

[17] The team has set up a cooperation with two local fitness clubs and is working together with most of the schools of Izegem.

[20] The logo features a crown, representing the title of "Royal", a favour bestowed on the club by the King of Belgium thanks to its 50 years of existence.

The waves in the logo symbolise the Mandel River, where the city of Izegem and the club are located on its southern bank.

The logo aims to mark the club's history, while giving it a new impulse, following the involvement of Strive Football Group.
