When the French Revolution began, many of the old foreign regiments were looked down upon after the King decided to bring in foreign regiments to crush the, then, rebellion. Therefore, on 1 January 1791 the regiment became the 4éme Régiment de Hussards (Saxe) in an effort by the National Assembly to remove the old strains of monarchy and the 'foreign troops'. Because of the majority of the regiment were composed of Germans from the nearby Duchy of Palatinate, almost all of the officers and men emigrated on 4 May 1792. When most of the men left, the main element of the 4th squadron remained, and was promptly grouped with a squadron from the late Régiment Royal Allemand Cavalerie to form the "Légion de la Moselle". In 1793, the regiment was officially disbanded, and the lineage ceased due to the mass emigration.
