The restoration of the monarchy and the resulting freedom given to the Church marked the period known as the Restoration. The two Bourbon kings who ruled were Louis XVIII (1814-1824) and Charles X (1824 – 1830). Yvon Beaudoin writes:
Father de Mazenod rarely used the word restoration, but he often mentions by name the kings Louis XVIII and Charles X. He exchanged correspondence with their ministers and met a few of them in the course of his trips to Paris in 1817, 1823 and 1825. It was with joy that he and the Mazenods greeted the return of the Bourbons in 1814. President Charles Anthony sent the king an act of homage and his oath of fidelity. During the Hundred Days, Eugene distinguished himself by displaying a fiery hostility to the Napoleonic regime. On July 7, 1815, he wrote his father:
I showed myself the most fearless royalist of the city where I live and there are perhaps few in France who can gainsay me on that point.
