History
The district as known today was created in 1969, during the reorganization of the districts in North Rhine-Westphalia, by merging Sieg District with the District of Bonn (from which Bonn itself was separated in 1887 to become an urban district). Sieg District was created in 1825.

District council
The district council consists of 88 seats, half of which are chosen directly in 44 constituencies. The remaining 44 seats are distributed via party lists, resulting in a proportional representation.
On 3 November 2020, the Christian Democrats and the Greens announced their coalition agreement, renewing their 21-year governance.[3]
District administrator
The district administrator is Sebastian Schuster. The Christian Democrat received 53.18% of the vote.[4][5]
Coat of arms
The red lion is the symbol of the dukes of Berg, who owned a large part of the district. The black cross in the shield is the symbol of Cologne, because another part of the district was owned by the bishops of Cologne. The yellow sword is the symbol of Saint Michael, the patron of the mighty Michaelsberg Abbey in Siegburg.
