On 11 February 1929, he signed a concordat and treaty with the Roman Catholic Church. The Concordat of 1801 suppressed its bishopric. In 1905 the 1801 Concordat was abrogated; Church and State were finally separated. Then, in 1905, a law was introduced that abrogated Napoleon's 1801 Concordat. The church closed in 1801, when Napoleon concluded a concordat with the Vatican. In January 1813, Napoleon personally forced the Pope to sign a humiliating "Concordat of Fontainebleau". The investiture controversy was finally resolved by the Concordat of Worms. On February 9, Henry V accepted the papal "Concordat of Sutri". The particular clauses of the Concordat were negotiated among the princes. Alsace-Lorraine is still governed by the 1801 Concordat which recognises four religions, but not secularism. Napoleon and the Pope both found the Concordat useful. Prussia showed interest in negotiations only after the Bavarian concordat. In 1984, an agreement was signed, revising the concordat. Galen often protested against violations of the Concordat to Hitler directly. Article 34 calls for the speedy ratification of the concordat.
