Twenty years ago, on the night of November 9, 1989, following weeks of pro-democracy protests, East German authorities suddenly opened their border to West Germany. After 28 years as prisoners of their own country, euphoric East Germans streamed to checkpoints and rushed past bewildered guards, many falling tearfully into the arms of West Germans welcoming them on the other side. Thousands of Germans and world leaders gathered in Berlin yesterday to celebrate the "Mauerfall" - the dismantling of the Berlin Wall and German reunification - and to remember the approximately 100-200 who died attempting to cross the border over the years. Collected here are photographs both historic and recent, from the fall of the Berlin Wall. Be sure to pause on photos 12 - 15, and click them to see a fade effect from before to after.
