Like his father, a Republican of the intransigent type, he was bitterly disappointed by the triumph of the monarchical principle after the Revolution of July 1830, in which he had taken part. He also participated in the Parisian uprisings of October 1830 during the trial of Charles X's ministers, 1832 and 1834. On the third occasion, he was imprisoned, but escaped to England in 1835.
When he returned to France in 1841, he worked on the staff of La Réforme, and produced energetic republican propaganda. In 1843, he became president of the Society of the Rights of Man, of which he had been one of the founders in 1832.
