November 9, 2014 marks the 25th anniversary of the fall of the Berlin Wall. The barrier between the eastern and western sectors of the German city began going up in 1961. On August 13 of that year, East German troops positioned themselves by the Brandenburg Gate and started sealing off the West-controlled part of Berlin. The wall, which ran 155 kilometers around West Berlin, meant almost certain death for those who wanted to cross to escape from the east. Twenty-eight years after it went up, the wall was unexpectedly opened and throngs of East German citizens poured through. The fall of the wall marked the beginning of the end of the communist-led regimes from Central Europe to Russia.
