The decision of the king to turn against Napoleon in 1814 was taken under the influence of his son and of Marshal Wrede rather than of Montgelas, although the minister would not have been influenced by any feeling of sentimentality to adhere to an ally who had ceased to be useful. In internal affairs, Montgelas carried out a policy of secularization and of administrative centralization by determined means, which showed that he had never wholly renounced his opinions of the time of the Enlightenment movement.
