==History== Originally called the Belgian International Championships it first established in 1899.<ref name="tb"/> The championships were not staged during World War I or World War II.<ref name="tb"/> In the pre-open era the event was often reported in Belgian press as the Brussels International, or International of the tennis club in Brussels it was held at. It was an ILTF-sanctioned event from 1897 until 1969.<ref name="tb"/> In 1968 the event was re branded as the Belgian Open Championships until 1970.<ref name="tb"/> In 1971 the women's event was discontinued, however the men's event carried on under the new brand name Belgian Open through till 1981 when it was discontinued.<ref name="tb"/> In 1970 the men's tournament was an ILTF-sanctioned independent event, then it joined the Grand Prix tennis circuit until 1972,<ref name="tb"/> before going back on to the previous circuit until 1976.<ref name="tb"/> Between 1977 and 1981 it was graded as Grand Prix event until the men's event ended.<ref name="tb"/>

The women's original tournament was part of the 1970 1970 ILTF Women's Tennis Circuit, and the 1971 ILTF Women's Tennis Circuit when that event was ended. In 1987 the tournament was revived as a women's event as part of the Virginia Slims World Championship Series tennis over three different periods during 1987–2002. The competition took place in July during 1987–1989 and 2002, and in May during 1992–1993 and 1999–2001. 2000 and 2001 it was sponsored by Dutch clothing chain Mexx and renamed the ''Benelux Open''.

The tournament was a Tier V event in 1992 and 2001, and a Tier IV event in 1993, 1999, 2000 and 2002. Only one Belgian woman won the singles event; the then little-known Justine Henin, aged 16 in 1999. However, Sabine Appelmans, Kim Clijsters and Els Callens all won the doubles event.
