2. Dubcek proposed the policy of 'socialism with a human face'
3. As Dubcek was committed communist the USSR approved of him replacing Novotny
4. New ideas started springing up as censorship was eased meaning people could expose corruption and criticise the failings of the communist rule and there was even talk of allowing other parties like the Social democratic party
5. The USSR was under pressure from other East European leaders (Polish and East german) who did not want these radical ideas to spread to their country.
6. The leaders of the USSR, Poland, Hungary, Bulgaria and East Germany sent Dubcek the Warsaw letter demanding that he stop the reforms to which Dubcek disagreed instead going on national television asking for support¥
7. The USSR tried different ways to slow Dubcek down: Intimidating the Czechs by performing public troop training exercises on the Czech border, they didn't impose trade sanctions as they didn't want the Czechs to have to turn to the West, they held a conference with Dubcek who agreed to not allow a SDP but insisted on the other reforms easing the tension
8. Soviet tanks moved into Czechslovakia in August 1968 and a coup was organised by the Czech communist party to remove Dubcek as leader
