Jules Auguste Armand Marie de Polignac, Count of Polignac, then Prince of Polignac, and briefly 3rd Duke of Polignac in 1847, was a French statesman and ultra-royalist politician after the Revolution. He served as prime minister under Charles X, just before the July Revolution in 1830 that overthrew the senior line of the House of Bourbon.

The Ultra-royalists were a French political faction from 1815 to 1830 under the Bourbon Restoration. An Ultra was usually a member of the nobility of high society who strongly supported Roman Catholicism as the state and only legal religion of France, the Bourbon monarchy, traditional hierarchy between classes and census suffrage, while rejecting the political philosophy of popular will and the interests of the bourgeoisie along with their liberal and democratic tendencies.
