Though the first permanent settlements have been traced back as far as the late 12th century, Berlin rose to fame when becoming the capital of the Kingdom of Prussia (1701–1918), the German Empire (1871–1918), the Weimar Republic (1919–1933) and the Third Reich (1933–1945). After the second World War, along with the country's division into East and West, the city was divided as well, by the infamous Berlin Wall. Following the German reunification in 1990, Berlin once more became the capital of Germany.
The Muppets have visited the city multiple times over the decades.
- Uli Von Bödefeld puppeteer Benita Steinmann, as well as Kermit voice artist Horst Gentzen and Robert Missler (second voice of second Grover and more recently puppeteering on Sesamstrasse spin-offs) were born in Berlin.
- In Die Muppets Erobern Manhattan, the German dub of The Muppets Take Manhattan, Kermit der Frosch claims his alternate identity, the "Boffo Socko" agent, to be from Berlin, and therefore talks with a heavy Berlin dialect (as noted above, voice actor Horst Gentzen was a Berlin native). The film was never released in East Germany.
- Baby Gonzo was seen in front of the Berlin Wall in Cartoon All-Stars to the Rescue, which aired in Germany as Comic-Stars gegen Drogen (Comic-Stars Against Drugs) in 1990. The character appeared on the painted west side, as people crossing the so-called "death strip" on the unpainted eastern side were at risk of being shot.
- Muppets, Monster & Magie was a Muppet exhibition that visited Berlin, showcasing Muppets from several productions. It was on display from June 2 to August 28, 1994 at the Filmmuseum Potsdam, Berlin.
- The Vision of Jim Henson was another Muppet exhibition that visited Berlin, showcasing Muppets from Sesamstrasse, Die Muppet Show, Die Fraggles and German co-production Secret Life Of Toys, as well as other Henson productions. The exhibition was held at the Berliner Fernsehturm (TV tower) From December 10, 1994 to February 12, 1995.
- On December 7, 1999, Kermit the Frog left his flipper-prints into a 40x40cm piece of green "cement" at an event hosted by Karin Kuschik at the Cinestar-Kino in Berlin-Tegel, planned to eventually grace the Sony Center's "Berlin Walk of Fame" at Potsdamer Platz. Steve Whitmire had Kermit say in German: "Dies ist ein kleiner Schritt für einen Frosch, aber ein großer Sprung für die Froschheit." ("This is one small step for a frog, but one giant leap for frogkind.")
- In a PBS interstitial, Big Bird and a little girl venture all over the world (and even the moon) and are seen (digitally) inserted into footage of the destruction of the Berlin Wall.
- In early 2006, Kermit the Frog appeared in an ad for Adidas to promote their Adicolor line, shot in winterly Berlin.
