ヴァレンヌ事件
The Padua Circular was a diplomatic note produced by Holy Roman Emperor Leopold II on 6 July 1791. Prompted by the arrest of Louis XVI and Marie Antoinette after the Flight to Varennes, the Circular called on the sovereigns of Europe to join him in demanding their freedom. It was followed by diplomatic initiatives in which the Holy Roman Empire looked for rapprochement with its traditional enemy, Hohenzollern Prussia.
