“Ideology was the main factor that led to the emergence of superpower rivalry between 1943 and 1949.” Discuss.

Candidates are required to offer a considered and balanced review of the hypothesis that ideology was the main factor that led to the emergence of superpower rivalry between 1943 and 1949. They may weigh ideology against other factors, but the role of ideological causes must be addressed. It may be valid to mention events before 1943 that had an impact lasting into the time period in question. However, candidates must not stray beyond 1949. Candidates may explain the ideological differences between the US and the USSR, but will link them to the emergence of superpower rivalry. They may also discuss the interaction of ideological and strategic factors, especially in respect of eastern Europe. Other factors for consideration may include the atomic bomb, the Marshall Plan and the role of personalities.
