King Charles X' attempt to impose governmental control of the press and change the electoral system on July 26th was opposed by the upper and middle bourgeoisie in three days of street violence (July 27th-29th). Charles X abdicated on July 30th. He attempted to nominate his grandson, the Comte de Chambord, as his successor, but Louis-Philippe was proclaimed “roi des français” on August 9th. His reign would be called the “July Monarchy”.
