Dietzenbach is the seat of Offenbach district in the Regierungsbezirk of Darmstadt in Hesse, Germany and lies roughly 12 km southeast of Frankfurt am Main on the river Bieber. Before the Second World War, the current town was a farming village with not quite 4,000 inhabitants. However, after the war, there was a considerable upswing in the population due to refugees settling in the community. From the 1970s onwards, Dietzenbach’s population rose rapidly, reaching some 33,000 by 2006. Just under a third of the inhabitants have roots in more than a hundred nations outside Germany.
