In 1968, seven Soviet intellectuals held a pioneering protest against the power of the Communist Party.

Held in Moscow's Red Square, the demonstration was against the Soviet decision to crush the reformist movement in Czechoslovakia known as the Prague Spring.

Although tiny in the number, the intellectuals attracted media attention in the West, even inspiring a protest song.
