The build-up to war

The rise of Indonesian nationalism and the threat of war in Europe led to unrest in the Netherlands East Indies.
Around 1900, the Netherlands East Indies was almost entirely under Dutch rule. Despite the ethical policy that gave the colony more independence, Indonesian nationalism developed rapidly. The Second World War in Europe also affected the Netherlands East Indies, as the Royal Netherlands East Indies Army (Koninklijk Nederlands Indisch Leger or KNIL) was mobilised against a possible attack by Japan.
