Charles X Suspends the Freedom of the Press in France, Provoking the July Revolution

On July 25, 1830 while a guest at Saint-Cloud, Charles X set forth a series of decrees known at the Four Ordinances of Saint-Cloud or the July Ordinances. The decrees were meant to calm the people of France, but had the opposite effect of angering French citizens.

Perhaps most significant among July Ordinances was the decree suspending the freedom of the press as published in the poster illustrated with this entry. 
"Journalists gathered in protest at the headquarters of the National daily, founded in January 1830 by Adolphe Thiers, Armand Carrel, and others. The final result was the July Revolution and Charles X's abdication and exile" (Wikipedia article on July Ordinances).
