Josef Koudelka’s landmark photographs of the Prague Spring and the resulting Soviet invasion. The Czech photographer Josef Koudelka was centre stage with his camera when the Soviet tanks rolled into Prague on 20 August 1968, photographing mass demonstrations and the confrontations between protestors and invading soldiers. Smuggled out of Czechoslovakia soon after the invasion, Koudelka’s stunning black-and-white pictures of the citizens of Prague swarming the streets as tanks rumble towards them were widely published in the West and remain the definitive images of those tumultuous days.
