PRAGUE—Fifty years ago Soviet tanks rolled into Prague to crush the Czechoslovak Communist government’s democratic reforms, ushering in a bloody occupation whose lessons many Czechs fear have been forgotten.
The anniversary, marked in Prague and the Slovak capital Bratislava by ceremonies, exhibitions and films about the ‘Prague Spring’ and its brutal suppression that began on Aug. 21, 1968, comes at a time of renewed influence for the long-marginalized Czech Communist Party in national politics.
