Charles's dissolution of the Chamber of Deputies, his "July Ordinances" which set up rigid control of the press, and his restriction of suffrage resulted in the July Revolution of 1830. The major cause of the regime's downfall, however, was that, while it managed to keep the support of the aristocracy, the Catholic Church and even much of the peasantry, the ultras' cause was deeply unpopular outside of parliament and with those who did not hold the franchise, especially the industrial workers and the bourgeoisie. A major reason was a sharp rise in food prices, caused by a series of bad harvests 1827–1830. Workers living on the margin were very hard-pressed, and angry that the government paid little attention to their urgent needs.
