military success of the Red Army in Central and Eastern Europe led to a consolidation of power in communist hands. In some cases, such as Czechoslovakia, this led to enthusiastic support for socialism inspired by the Communist Party and a Social Democratic Party willing to fuse. In other cases, such as Poland or Hungary, the fusion of the Communist Party with the Social Democratic Party was forcible and accomplished through undemocratic means. In many cases, the communist parties of Central Europe were faced with a population initially quite willing to reign in market forces, institute limited nationalisation of industry and supporting the development of intensive social welfare states, whereas broadly the population largely supported socialism. However, the purges of non-communist parties that supported socialism, combined with forced collectivisation of agriculture and a Soviet-bloc wide recession in 1953 led to deep unrest. This unrest first surfaced in Berlin in 1953, where Brecht ironically suggested that "the Party ought to elect a new People". However, Nikita Khrushchev's "Secret Speech" of 1956 opened up internal debate, even if members were unaware, in both the Polish and Hungarian communist parties. This led to the Polish crisis of 1956 which was resolved through change in Polish leadership and a negotiation between the Soviet and Polish parties over the direction of the Polish economy. Hungarian Revolution of 1956 The Hungarian Revolution of 1956 was a major challenge to Moscow's control of Eastern Europe. This revolution saw general strikes, the formation of independent workers councils, the restoration of the Social Democratic Party as a party for revolutionary communism of a non-Soviet variety and the formation of two underground independent communist parties. The mainstream Communist Party was controlled for a period of about a week by non-Soviet aligned leaders. Two non-communist parties that supported the maintenance of socialism also regained their independence. This flowering of dissenting communism was crushed by a combination of a military invasion supported by heavy artillery and airstrikes; mass arrests, at least a thousand juridical executions and an uncounted number of summary executions; the crushing of the Central Workers Council of Greater Budapest; mass refugee flight; and a worldwide propaganda campaign. The effect of the Hungarian Revolution on other communist parties varied significantly, resulting in large membership losses in Anglophone communist parties. Prague Spring of 1968 The Czechoslovak Communist Party began an ambitious reform agenda under Alexander Dubček. The plan to limit central control
