The mood in the Slovak region of the country changed sharply after 1960, however. The new ‘Socialist’ Constitution made even fewer concessions to local initiative or opinion than its predecessor and such autonomy as had been accorded Slovakia in the post-war reconstruction of the country was now taken back. Of more immediate consequence for most Slovaks, however, was the stagnation of the economy (by 1964 Czechoslovakia’s rate of growth was the slowest in the bloc), which hit the heavy industry of central Slovakia harder than anywhere else.
