FILE--About 200,000 people gather on Wenceslas Square in Prague, Czechoslovakia on Nov. 21, 1989. Theirs was the Velvet Revolution, a peaceful revolt born of police brutality that ended four decades of communism with songs, laughter and not a few tears. Ten years later, there is little celebration. On that Nov. 17, 1989, protesters were scattered by communist police, but came back the next day and the next - in ever growing numbers that led to the collapse of the Marxist regime in only 18 astounding days. Sign at center (back side shown to camera) translates, "Free elections." (AP Photo/Peter Dejong)
