This case study for Paper 1 explores Japanese expansionism from 1931 to 1941. The focus of this prescribed subject is on the causes of expansion, key events, and international responses to the expansion. Discussion of domestic and ideological issues should therefore be considered in terms of the extent to which they contributed to this expansion, for example, economic issues, such as the long-term impact of the Great Depression, should be assessed in terms of their role in shaping more aggressive foreign policy.
