In this 1994 book Graeme Gill traces the disintegration of the Communist Party of the Soviet Union from 1985 until the dissolution of the USSR in December 1991. Based principally on the contemporary Soviet press, the book to follows the debates in the party over the implications of Gorbachev's reforms and how the party should respond to them. It is an in-depth analysis of the institutional dynamics of a party under pressure. When it came under challenge and it could no longer use the weapon of suppression, the party was unable to mount a serious defence of its position and role. Confronted from the top by Gorbachev's call to reform itself and by his changes to the political arena, and from the bottom by new political forces taking advantage of that arena, the party's unity collapsed and with it any sense of purpose or possibility of survival.
