History of incorporations

Until the year 1877 the city's territory consisted of the present-day inner-city districts of Altstadt, Innenstadt, Bahnhofsviertel, Gutleutviertel, Gallus, Westend, Nordend, Ostend and Sachsenhausen.

Bornheim was part of an administrative district called Landkreis Frankfurt, before becoming part of the city on 1 January 1877, followed by Bockenheim on 1 April 1895. Seckbach, Niederrad and Oberrad followed on 1 July 1900. The Landkreis Frankfurt was finally dispersed on 1 April 1910, and therefore Berkersheim, Bonames, Eckenheim, Eschersheim, Ginnheim, Hausen, Heddernheim, Niederursel, Praunheim, Preungesheim and Rödelheim joined the city. In the same year a new city district, Riederwald, was created on territory that had formerly belonged to Seckbach and Ostend.

On 1 April 1928 the City of Höchst became part of Frankfurt, as well as its city districts Sindlingen, Unterliederbach and Zeilsheim. Simultaneously the Landkreis Höchst was dispersed with its member cities either joining Frankfurt (Fechenheim, Griesheim, Nied, Schwanheim, Sossenheim) or joining the newly established Landkreis of Main-Taunus-Kreis.

Dornbusch became a city district in 1946. It was created on territory that had formerly belonged to Eckenheim and Ginnheim.

On 1 August 1972, Hesse's smaller suburbs of Harheim, Kalbach, Nieder-Erlenbach, and Nieder-Eschbach became districts while other neighboring suburbs chose to join the Main-Taunus-Kreis, the Landkreis Offenbach, the Kreis Groß-Gerau, the Hochtaunuskreis, the Main-Kinzig-Kreis or the Wetteraukreis.

Bergen-Enkheim was the last suburb to become part of Frankfurt on 1 January 1977.

Flughafen became an official city district in 1979. It covers the area of Frankfurt Airport that had belonged to Sachsenhausen and the neighboring city of Mörfelden-Walldorf.

Frankfurt's youngest city district is Frankfurter Berg. It was part of Bonames until 1996.

Kalbach was officially renamed Kalbach-Riedberg in 2006 because of the large residential housing development in the area known as Riedberg.
