Comte de (1749-1791) French politician, leader of the National Assembly in the French Revolution. He wanted to establish a parliamentary monarchy on the English model. From May 1790 he secretly acted as political adviser to the king.
Mirabeau was from a noble Provençal family. Before the French Revolution he had a stormy career, was three times imprisoned, and spent several years in exile. In 1789 he was elected to the States General. His eloquence won him the leadership of the National Assembly; nevertheless, he was out of sympathy with the majority of the deputies, whom he regarded as mere theoreticians.
