In 1969, the urban area expanded with the annexation of the township of Sieglar and the villages of Altenrath and Friedrich-Wilhelms-Hütte (total population in 1969: about 51,000). The first large settlements in this area go back to the 9th and 10th century (Eschmar and Sieglar 832, Bergheim 987). The first churches in this area were built around 700 AD in Bergheim (St. Lambertus). ^{[citation needed]}

In the years following the Peaceful Revolution and German reunification of 1989/1990 many migrants from Russia and other East European countries settled in Troisdorf.
