In the 1960s, Soviet ideology came face to face with new challenges and threats, both internal and external. The leadership of the USSR was aware of these challenges and decided to rework the ideology on the basis of the concept of ‘Developed Socialism’ created in the socialist countries of Eastern Europe. In the Soviet Union, this concept became the ideological basis of the ‘Brezhnev’s society’ and was used to respond to domestic and foreign policy challenges faced by the Soviet Union.
