In 1173, the village was still called Rekkem, similar to Reclinghem in Artois and to Rijkegem (Tielt), which were founded by the Viking Rikiwulf in 876 .
The last complete linguistic census of 1947 indicated that over one quarter of the population used French as the "Language exclusively or most frequently spoken".
The Dronckaertstraat (the former road between Courtrai and Lille) and the A14 motorway (European route E17) pass between the centre of Rekkem and the village of Paradijs.
In 1963, during the finalisation of the linguistic frontier, the hamlet of Risquons-Tout (0.39 km2 - approximately 500 inhabitants) was transferred from the commune of Rekkem to the city of Mouscron.
