Érasme-Louis, Baron Surlet de Chokier, born in Liège, was a Belgian politician and, before the accession of Leopold I to the Belgian throne, was the first Regent of Belgium.
During the Liège Revolution of 1789, when a crowd followed the example of the French Revolution and drove off Prince-Bishop of Liège César-Constantin-François, Surlet de Chokier served in the patriotic army. When the following year this army was defeated by the Austrians at Hasselt and Zutendaal, Surlet de Chokier was forced to flee to Breda, not being able to return to Gingelom until 1792.
After the French annexation of Liège, Surlet de Chokier became a devoted follower of the French revolution and of Napoleon. In 1800, Surlet de Chokier was elected mayor of Gingelom and member of the départemental council of Meuse-Inférieure. In 1812, he became a member of the French parliament.
After the fall of Napoleon, Surlet de Chokier entered the House of Representatives of the Staten-Generaal as leader of the Southern opposition, where his opposition to the government gave him the nickname Surlet de Choquant.
