Russian Tanks in Prague

In the night of 20 August 1968 Soviet tanks and those of its allies rolled into the Czechoslovak capital Prague. This action ended the "socialism with a human face", the political liberalization that lasted half a year. The invaders did not encounter any military resistance, but this made the non-violent protest of civilians stand out even more. Instead of the expected warm welcome, the troops were booed and mocked and confronted with graffiti, posters, and banners.
