PRAGUE, CZECH REPUBLIC - NOVEMBER 17:  People show red cards as they shout slogans against Czech Republic President Milos Zeman before the unveiling of a plaque on the 25th anniversary of the Velvet Revolution on November 17, 2014 in Prague, Czech Republic. Prague is commemorating the anniversary with a variety of events, including the unveiling of a plaque by the presidents of the Czech Republic, Germany, Hungary, Poland and Slovakia. In November, 1989, hundreds of thousands of people took to the streets of Prague and other cities across what was then still communist Czechoslovakia to demand political reforms and greater freedoms. The communist leadership soon crumbled and the playwright and human rights activist Vaclav Havel became president shortly thereafter.  (Photo by Matej Divizna/Getty Images)
