In August 1829, Charles X had decided to show his authority over the unruly Chamber of Deputies, and named a fervent royalist, Jules de Polignac as his new prime minister. On 19 March 1830, he raised the temperature, warning that if the deputies put obstacles in his path, he would "find the force to overcome them in my resolution to maintain the public peace, with the full confidence of the French and the love they have also shown toward their King." He also launched an overseas expedition for the conquest of Algeria, which he was certain would increase his popularity at home, and called for new elections, which he was certain he would win. The French flag was hoisted over Algiers on 5 July 1830, and new elections were held from 13 to 19 July. The elections were a disaster for the King; the opposition won 270 seats, against 145 supporters of the King. The opponents were, for the most part, not republicans; they simply wanted a constitutional monarchy. The King responded, however, on 25 July with new decrees dissolving the Chamber of Deputies, changing the election laws, and putting restrictions on the press. The King, confident in his popularity, neglected to put the army on alert or to bring in soldiers to maintain order.
