Several military units have been known as the Belgian Legion. The term "Belgian Legion" can refer to Belgian volunteers who served in the French Revolutionary Wars, Napoleonic Wars, Revolutions of 1848 and, more commonly, the Mexico Expedition of 1867. French Revolutionary era The French Revolutionary armies incorporated a number of "legions" of foreign volunteers during the French Revolutionary Wars after 1792. These included a number of units recruited among exiles from the failed Brabant (1789–90) and Liège revolutions (1789–91). A number of separate units were organised, including: Belgian Legion (Légion belge or Légion belgique), with two battalions; Liégeois Legion (Légion liégeoise), with two battalions; Legion of Belgians and Liégeois (Légion des Belges et Liégeois), with six battalions. These units incorporated a number of influential revolutionary figures, including Jean-Baptiste Dumonceau and Louis Lahure who both served in the Belgian Legion. Restoration Temporarily regaining control of the Southern Netherlands, on 2 March 1814, Austria formed several military units from regional recruitment. This volunteer force was known as the Légion belge (Belgian Legion) and initially was intended to strengthen the Austrian position in their former provinces in the event of a counterattack from France. With the full occupation of the Southern Netherlands by Austria, Prussia and the United Provinces (Holland), a provisional government was established under the Duke of Beaufort and local levies continued to be recruited separately by each of the three allies. The largest of these was the Belgian Legion which, under the command of the Belgian born Austrian General Count von Murray, was now intended to keep local order. Administrated by the Baron Poederlé, secretary general for armaments, this Legion was made up of 4 line infantry regiments (from Brabant, Flanders, Hainaut and Namur), a light infantry regiment, two cavalry regiments and an artillery regiment. This unit merged into the army of the Kingdom of the Netherlands on 1 September 1814, when that nation annexed the territory that would later form Belgium. French Revolution of 1848 In March 1848, during the French Revolution of 1848, Belgian workers living in Paris formed an "Association des démocrates belges" (94, rue de Ménilmontant), led by Blervacq a wine merchant and an old officer called Fosses. This gave rise to a new Belgian Legion. Informally supported by Ledru-Rollin, Caussidière and other members of the French government dreaming of a Republican uprising in the Southern Netherlands and a subsequent French annexation of that area, this
