Karlsruhe is twinned with the cities of Nancy (France), Nottingham (England), Halle (in the northern German state of Saxony-Anhalt), Krasnodar (Russia) and Timişoara (Romania).
The twinning with Nancy has been in place for over 50 years and in 2009 Karlsruhe celebrated the 40th anniversary of its twinning with Nottingham. In 1989, two years before German reunification, Karlsruhe became one of the first cities in former West Germany to forge contacts with a city in East Germany, making the bold move of looking for a twin city there.
As the borders of eastern Europe opened up, existing connections to the cities of Timişoara (Romania) and Krasnodar (Russia) intensified, and in the course of the 1990s, both cities twinned with Karlsruhe.
