It was he who after Austerlitz aggrandized the margravate at the expense of Austria; transformed it into a sovereign principality and raised it to a Grand Duchy. It was he too who, by the secularization on the one hand and by the dismemberment of Württemberg on the other, gave the Grand Duke 500,000 new subjects. He believed that the recognition of the prince and the artificial ethnical formation of the principality would be pledges of security for France. But in 1813 Baden joined the coalition, and since then that nation created of odds and ends ("de bric et de broc") and always handsomely treated by us, had not ceased to take a leading part in the struggles against our country. The Grand Duke Frederick, Grand Duke by the will of Napoleon, has done France all the harm he could. But French opinion itself renders justice to the probity of his character and to the ardour of his patriotism, and nobody will feel surprise at the homage with which Germany feels bound to surround his old age. Grand Duke Frederick I died at Mainau on 28 September 1907. He was succeeded by his son, the Grand Duke Frederick II (ruled 1907–1918, died 1928). The Grand Duchy of Baden was a hereditary monarchy with executive power vested in the Grand Duke; legislative authority was shared between him and a representative assembly ("Landtag") consisting of two chambers. The upper chamber included all the princes of the ruling family of full age, the heads of all the mediatized families, the Archbishop of Freiburg, the president of the Protestant Evangelical Church of Baden, a deputy from each of the universities and the technical high school, eight members elected by the territorial nobility for four years, three representatives elected by the chamber of commerce, two by that of agriculture, one by the trades, two mayors of municipalities, and eight members (two of them legal functionaries) nominated by the Grand Duke. The lower chamber consisted of 73 popular representatives, of whom 24 were elected by the burgesses of certain communities, and 49 by rural communities. Every citizen of 25 years of age, who had not been convicted and was not a pauper, had a vote. The elections were, however, indirect. The citizens selected the "Wahlmänner" (deputy electors), the latter selecting the representatives. The chambers met at least every two years. The lower chambers were elected for four years, half the members retiring every two years.
