ヴァレンヌ事件
The royal Flight to Varennes () during the night of 20–21 June 1791 was a significant episode in the French Revolution in which King Louis XVI of France, Queen Marie Antoinette, and their immediate family unsuccessfully attempted to escape from Paris in order to initiate a counter-revolution at the head of loyal troops under royalist officers concentrated at Montmédy near the frontier. They escaped only as far as the small town of Varennes-en-Argonne, where they were arrested after having been recognized at their previous stop in Sainte-Menehould.
