Offenburg ("open borough" - coat of arms showing open gates; Low Alemmanic: Offäburg) is a city located in the state of Baden-Württemberg, Germany. With nearly 60,000 inhabitants (2019), it is the largest city and the administrative capital of the Ortenaukreis. In recent times the remains of Roman settlements have been found within the city's territory. Offenburg was first mentioned in historical documents dating back to 1148. Offenburg had already been declared a Free Imperial City by 1240. In September 1689, the city - with the exception of two buildings - was totally destroyed by the French during the Nine Years War. Due to Napoleon's dissolution of the Holy Roman Empire in 1803 and subsequent reorganization of the German states, Offenburg lost its status as a Free Imperial City and fell under the rule of the Grand Duchy of Baden. During the outbreak of the Revolutions of 1848, the "Offenburger Programm" which consisted of thirteen demands "in the name of the people of Baden", was put forward at the Salmen Inn on 12 September 1847. This was the first known demand for democracy in Germany. Along with the Carlsbad Decrees, the Offenburger Program demanded basic and human rights as well as freedom of the press and a progressive income tax structure. On 19 March 1848 the demands were confirmed by the 20,000 member Offenburg Peoples' Assembly. During World War I Offenburg was one of the first cities to experience the effects of aerial bombardment, the operations against Offenburg railway sidings were mostly flown by aircraft from the Independent Force from Ochey aerodrome. It is mostly neglected, that in the aftermath of World War I, during the Occupation of the Ruhr, French troops occupied Offenburg, because it fell within the perimeter of the Kehl bridgehead. The French occupation forces entered the town in February 1923 and remained until 1924, blocking all traffic on the Rhine Valley Railway between Offenburg and Appenweier.
