Popular opposition was expressed in numerous spontaneous acts of nonviolent resistance.
In Prague and other cities throughout the republic, Czechs and Slovaks greeted Warsaw Pact soldiers with arguments and reproaches.
Every form of assistance, including the provision of food and water, was denied to the invaders.
Signs, placards, and graffiti drawn on walls and pavements denounced the invaders, the Soviet leaders, and suspected collaborationists.
Pictures of Dubček and Svoboda appeared in the streets.
Citizens gave wrong directions to soldiers and even removed street signs (except for those giving the direction back to Moscow).

Initially, some civilians tried to argue with the invading troops, but this met with little or no success.
After the USSR used photographs of these discussions as proof that the invasion troops were being greeted amicably, secret Czechoslovak broadcasting stations discouraged the practice, reminding the people that "pictures are silent".
The protests in reaction to the invasion lasted only about seven days.
Explanations for the fizzling of these public outbursts mostly centre on demoralisation of the population, whether from the intimidation of all the enemy troops and tanks or from being abandoned by their leaders.
Many Czechoslovaks saw the signing of the Moscow Protocol as treasonous.
Another common explanation is that, due to the fact that most of Czech society was middle class, the cost of continued resistance meant giving up a comfortable lifestyle, which was too high a price to pay.

The generalised resistance caused the Soviet Union to abandon its original plan to oust the First Secretary.
Dubček, who had been arrested on the night of 20 August, was taken to Moscow for negotiations.
It was agreed that Dubček would remain in office, but he was no longer free to pursue liberalisation as he had before the invasion.

On 19 January 1969, student Jan Palach set himself on fire in Wenceslas Square in Prague to protest the renewed suppression of free speech.

Finally, on 17 April 1969, Dubček was replaced as First Secretary by Gustáv Husák, and a period of "Normalization" began.
Pressure from the Soviet Union pushed politicians to either switch loyalties or simply give up.
In fact, the very group that voted in Dubček and put the reforms in place were mostly the same people who annulled the program and replaced Dubček with Husák.
Husák reversed Dubček's reforms, purged the party of its liberal members, and dismissed the professional and intellectual elites who openly expressed disagreement with the political turnaround from public offices and jobs.
