Passage: On 20 September 1792, the recording of births, marriages, and deaths also was withdrawn as a responsibility of the priests of the parishes and handed to the mayors. Civil marriages were established and started to be performed in the mairie with a ceremony not unlike the traditional one, with the mayor replacing the priest, and the name of the law replacing the name of God ("Au nom de la loi, je vous déclare unis par les liens du mariage." – "In the name of the law, I declare you united by the bonds of marriage."). Priests were forced to surrender their centuries-old baptism, marriage, and burial books, which were deposited in the mairies. These abrupt changes profoundly alienated devout Catholics, and France soon was plunged into the throes of civil war, with the fervently religious regions of western France at its center. It would take Napoleon I to re-establish peace in France, stabilize the new administrative system, and make it generally accepted by the population. Napoleon also abolished the election of the municipal councils, which now were chosen by the prefect, the local representative of the central government.
