Berlin
city in Brandenburg, capital of modern Germany. Folk-etymology derives it from German Bär "bear," but it is likely from a Slavic source (compare Old Polabian berl-, birl- "swamp"), from PIE *ber- "marshy place," in reference to the old city's location on low, marshy ground along the River Spree. A flashpoint city in the Cold War, the Berlin airlift ran from June 28, 1948 to May 12, 1949. The Berlin Wall began to be built Aug. 15, 1961, and was effective until Nov. 9, 1989. Related: Berliner.
