Concordat of 11 June 1817

Not having been enacted into law by the French parlement, it never came into force in France.

The country remained under the regime outlined in the Concordat of 1801 until the 1905 law on the Separation of the Churches and the State was enacted.

Representing Pope Pius VII was Cardinal Ercole Consalvi, the papal Secretary of State.

King Louis XVIII of France chose his favorite, the Ambassador to Rome, the Comte de Blacas, who had previously served as the Prime Minister of France, to negotiate the Concordat of 1817.

Another important article (article 4) stipulated that the dioceses in the kingdom of France suppressed by the bull of the Holy See of 29 November 1801 were to be re-established in such a number as both sides would agree on as the most advantageous for the good of religion.
