Interactive visualization showing how centrifugal forces pull regions away from national centres, the regional, ethnic, religious and class divisions behind them, and the five tools governments use to manufacture a national identity: nationalism, propaganda, language policy, education and force

The centre cannot hold

New nations inherit borders drawn by empires, not the unity within them. From Indonesia's archipelago to India's partition, the twentieth century proved that declaring independence is the easy part — holding the pieces together is the work. Drag the slider to see how centrifugal forces pull regions outward.

Centrifugal Tension MINIMAL STRAIN
Regions strain outward as separatist pressure builds. Four kinds of fault line do the pulling.
REGIONS UNDER MINIMAL TENSION
Regional · geography and distance
Ethnic · descent and language
Religious · confession and law
Class · who the state enriches

Indonesia declared independence from the Netherlands in 1945, but the archipelago of 17,000 islands spoke 300 languages across regions that had never governed together. East Timor resisted integration from the start, Aceh demanded Islamic autonomy in the north, and Irian Jaya (West Papua) had more cultural ties to Melanesia than Java. Jakarta spent decades suppressing separatist movements with military force, but the centre could not manufacture unity where geography, language, and religion all pulled outward. East Timor finally broke free in 2002 after a referendum, proving that some centrifugal forces cannot be countered indefinitely.
Know This
National unity is manufactured against centrifugal forces — region, language, religion — that pull territories outward, which is why twentieth-century states invested heavily in integration mechanisms like national languages and symbolic unification campaigns to counter the separatist pressures inherited from colonial borders. Learn both halves as lists. The divisions pulling outward are regional, ethnic, religious and class. The tools pulling inward are nationalism, propaganda, language policy, education and force — five ways of manufacturing one national identity where none existed. Force is the one that shows the project has already failed.
