The Berlin Conference (1884–1885) was indeed held in Germany—specifically in Berlin, the capital of the German Empire under Chancellor Otto von Bismarck.
The conference convened at the Reich Chancellery from November 15, 1884, to February 26, 1885. It was hosted by Bismarck to regulate European colonization and trade in Africa during the "Scramble for Africa." No African representatives were present.
The premise that it was *not* held in Germany is incorrect; Berlin was the chosen neutral ground for the European powers.
