The Gemeinderat, formed for the first time after the revolution in 1848 on the basis of the provisional municipal law of March 17, 1849, issued by the imperial patent, was correspondingly enlarged in the following decades. After the incorporation of
Floridsdorf in 1904/1905 the
Gemeinderat comprised 165 representatives until 1923. The legal provisions for this were decided by the
Landtag of Lower Austria as the State Law. The municipal council could only be elected by all citizens living in Vienna after 1918. Before then, the leading classes of Vienna and Lower Austria had prevented the general right to vote, realized for men in
Cisleithania in 1907, in the municipal and state policy. In the Vienna city constitution, the Gemeinderat is mentioned before the Landtag, as was decided by the
Federal Constitutional Law, which entered into force on the same day as the city constitution. It is, therefore, the municipal council that is the supreme
collegial body of the
statutory city of Vienna. In 1923, the number of representatives in the Gemeinderat/Landtag was reduced to 120, and in 1929 (first applied in the 1932 election) to 100 (the number it still has today). In the
Austrofascist dictatorship of 1934-1938, the municipal council was replaced by the parliament of Vienna. The Gemeinderat has elected the mayor (who since November 10, 1920, also serves as the
Landeshauptmann, or governor of the state of Vienna) and the (executive) city councils since June 1, 1920. These have also functioned simultaneously as members of the Viennese regional government since November 10, 1920. In addition, the Gemeinderat controls all other community bodies and decides on budget and clearance (including the state budget, which is not separate). It also decides on all the city's major expenditures, the city plan, the service plan and the business division for Wiener Stadtsenat and the Viennese provincial government. It is, therefore, a very busy body, also with the municipal councils for the individual business groups of the magistrate. The municipal council is to be understood legally as an organ of the executive branch, since municipalities in Austria do not have their own legislation, but have to implement federal and state laws. Since 1918, the
Social Democrats have been the largest party in the Municipal Council/Landtag at every free election. The only break in this tradition came from 1934 to 1945, when the democratic form of government was interrupted and the mayors were appointed by the government (by the
Austrofascist Federal State of Austria from 1934 to 1938, and by the Nazis from 1938 to 1945). The pre-1934 legal situation was restored with the return of peace in 1945. ==Landtag of Vienna==
