After the fall of the monarchy, Philippe risked his own life by saving suspects of the revolutionary regime. At the request of Grace Elliott, he saved the life of Louis René Quentin de Richebourg de Champcenetz, the governor of the Tuileries Palace, who was his personal enemy. He accepted the title "Citoyen Égalité" given to him by the Commune. He was elected 20th and last deputy for Paris to the National Convention, where he again made no notable contribution other than voting in the king's trial. He voted in support of the death sentence for Louis XVI. Many citizens of Paris saw this as an attempt by Philippe to overthrow the crown and take power himself. They believed that not only was the Palais-Royal the center for revolutionary and philosophical debates, but that it was also his ground for recruiting and financing riots and rebellious activity.
