The history of Freemasonry in Belgium reflects the many influences on what is now Belgium from the neighbouring states.
In the 18th century, Belgium was made up of 2 states - the Austrian Netherlands and the Prince-Bishopric of Liège.
Freemasonry in the Austrian Netherlands was very varied in its origins and expressions. The source of this fragmentation was to be found particularly in the complexity of its institutions, the influence of the government or surrounding powers, and its very deeply rooted local sense of identity.
The first Belgian lodge was founded in 1721 in Mons, under the name "La Parfaite Union" ("The Perfect Union"). It has frequently changed its name and allegiance since then, but still exists today as number 1 of the Grand Orient of Belgium. Other, more short-lived lodges seem to have been created in Ghent and Tournai in 1730. The first evidence of masonic activity in the provinces dates to 1743, in Brussels. This would be the "La Discrète Impériale" ("The Discrete Imperial") lodge of Aalst which would have number one on the tablet of the order of the Provincial Grand Lodge (Grande loge provinciale) of the Austrian Netherlands, the mother-lodge of London several times recognising it as the oldest in the region. It disappeared with the Provincial Grand Lodge of the Austrian Netherlands.
Thanks to the War of the Austrian Succession, from 1746 several lodges formed under the influence of French forces occupying the country and of the Grand Lodge of France (of which a French prince de sang, Louis de Bourbon Condé, Comte de Clermont, was Grand Master). These lodges received their patents from the Grand Lodge of France, the Grand Lodge of London, the Grand Lodge of Holland or the Grand Lodge of Scotland - for example, the "Parfaite Union" ("Perfect Union") Lodge at Namur, one of the "ancient" lodges, which in 1777 became the "Bonne Amitié" ("Good Friendship") lodge in Namur). After the Treaty of la Barrière in 1715, Batavian troops (also including English and Scottish troops) occupied the strongholds of the Austrian Netherlands (notably Namur, Tournai, Veurne, Ypres, Warneton) for a long and difficult period, and it was probably this that led to the creation or confirmation of more lasting lodges.
