I stood with hundreds of thousands of rebellious Czechoslovakians in 1989 on a cold winter night in Prague’s Wenceslas Square as the singer Marta Kubišová approached the balcony of the Melantrich building. Kubišová had been banished from the airwaves in 1968 after the Soviet invasion for her anthem of defiance, “Prayer for Marta.” Her entire catalog, including more than 200 singles, had been confiscated and destroyed by the state. She had disappeared from public view. Her voice that night suddenly flooded the square. Pressing around me were throngs of students, most of whom had not been born when she vanished. They began to sing the words of the anthem. There were tears running down their faces. It was then that I understood the power of rebellion. It was then that I knew that no act of rebellion, however futile it appears in the moment, is wasted. It was then that I knew that the Communist regime was finished.

“The people will once again decide their own fate,” the crowd sang in unison with Kubišová.

I had reported on the fall of East Germany before I arrived in Prague. I would leave Czechoslovakia to cover the bloody overthrow of the Romanian dictator Nicolae Ceaucescu. The collapse of the Communist regimes in Eastern Europe was a lesson about the long, hard road of peaceful defiance that makes profound social change possible. The rebellion in Prague, as in East Germany, was not led by the mandarins in the political class but by marginalized artists, writers, clerics, activists and intellectuals such as Vaclav Havel, whom we met with most nights during the upheavals in Prague in the Magic Lantern Theater. These activists, no matter how bleak things appeared, had kept alive the possibility of justice and freedom. Their stances and protests, which took place over 40 years of Communist rule, turned them into figures of ridicule, or saw the state seek to erase them from national consciousness. They were dismissed by the pundits who controlled the airwaves as cranks, agents of foreign powers, fascists or misguided and irrelevant dreamers.
