Johann Peter de Beaulieu, also Jean Pierre de Beaulieu, was a Walloon military officer. He joined the Habsburg army and fought against the Prussians during the Seven Years' War. A cultured man, he later battled Belgian rebels and earned promotion to general officer. During the French Revolutionary Wars he fought against the First French Republic and attained high command. In 1796, a young Napoleon Bonaparte won some of his first victories against an army led by Beaulieu. He retired and was the Proprietor (Inhaber) of an Austrian infantry regiment until his death.

The Low Countries theatre of the War of the First Coalition, in British historiography better known as the Flanders campaign, was a series of campaigns in the Low Countries conducted from 20 April 1792 to 7 June 1795 during the first years of the War of the First Coalition. As the French Revolution radicalised, the revolutionary National Convention and its predecessors broke the Catholic Church's power (1790), abolished the monarchy (1792) and even executed the deposed king Louis XVI of France (1793), vying to spread the Revolution beyond the new French Republic's borders, by violent means if necessary. The First Coalition, an alliance of reactionary states representing the Ancien Régime in Central and Western Europe – Habsburg Austria, Prussia, Great Britain, the Dutch Republic, Hanover and Hesse-Kassel – mobilised military forces along all the French frontiers, threatening to invade Revolutionary France and violently restore the monarchy. The subsequent combat operations along the French borders with the Low Countries and Germany became the primary theatre of the War of the First Coalition until March 1796, when Napoleon took over French command on the Italian front.
