Historical context
The Blitar Rebellion occurred in February 1945. It was a mutiny by the PETA (Pembela Tanah Air) forces in Blitar, East Java, against their Japanese occupiers during WWII. The geography of East Java, with its dense vegetation and strategic plantation landscape, played a significant role in how the uprising was organised and suppressed.
Reading material
The Blitar Rebellion of 1945 was a pivotal moment in the lead-up to Indonesian independence. The PETA forces, trained by the Japanese military, turned against their commanders. Geographically, East Java offered both advantages and challenges. Its volcanic soil supported vast plantations, which provided cover but also restricted movement to specific paths and roads.

Discussion questions
- How does the local landscape dictate the types of weapons or tactics used in a rebellion?
- Why might a military force choose to start an uprising in a rural location like Blitar rather than an urban center?
- Does 10 seconds provide enough information to understand the 'place' where a historical event occurred?
Extension task
Research the 'scorched earth' policies often used in colonial wars and how they permanently altered the agricultural geography of East Java.
Support prompts
- Think about how the shape of the land (mountains vs. plains) changes how an army travels.
- Consider the difference between a dense forest and an open city street for a soldier.
- Look at a map of Java: is it mountainous or flat?
