Originally, the constituency was coterminous with the Siegkreis district. In the 1965 through 1976 elections, it comprised the district of Landkreis Bonn as well as the modern municipalities of Bad Honnef, Königswinter, Niederkassel, Troisdorf, and Sankt Augustin from the Siegkreis district. It acquired its current borders in the 1980 election.
The constituency has been held by the Christian Democratic Union (CDU) during all but two Bundestag terms since its creation in 1949. It was first represented by Peter Etzenbach of the CDU from 1949 to 1961, followed by Georg Kliesing under 1976. Franz Möller served a single term from 1976 to 1980, being succeeded by Adolf Herkenrath. Andreas Krautscheid was elected in 1994 and served a single term. The Social Democratic Party (SPD) won the constituency in 1998, and Uwe Göllner served as representative. The CDU regained it in 2005 with candidate Elisabeth Winkelmeier-Becker. She was re-elected in 2009, 2013, 2017, and 2021.
