Input: Question: How old was the Duke of Richelieu when he removed Maurepas from power? Passage:In 1749, Maurepas was removed by a coup led by Duke of Richelieu, putting an end to his period of immense success. He was exiled from Paris for an epigram against Madame de Pompadour, and went to Bourges and then onto Pontchartrain. In 1774, he was appointed to minister of state to Louis XVI, as well as chief adviser, holding both positions until 1781. He gave Turgot the direction of finance, placed Lamoignon-Malesherbes over the royal household and made Vergennes minister for foreign affairs. At the outset of his new career he showed his weakness by recalling to their functions, in deference to popular clamour, the members of the old Parlement ousted by Maupeou, thus reconstituting the most dangerous enemy of the royal power. This step, and his intervention on behalf of the American states, helped to pave the way for the French Revolution.
