German people are often active on November 9

So, what do I mean? Well, Wilhelm II abdicated and a Republic was proclaimed on November 9, 1918, which was a Saturday. In 1938, Kristallnacht started in the evening of November 9, which was a Wednesday, and in 1989, on a Thursday, the Berlin Wall fell. Three main events on November 9 and two of them meant the end of undemocratic social systems.
