Unity in Diversity

The national motto "Bhinneka Tunggal Ika" ("Unity in Diversity") captures Indonesia's essence: 1,300+ ethnic groups, 700+ languages, six official religions, all united under the Indonesian language (Bahasa Indonesia) and Pancasila state philosophy.

From Aceh's Islamic law to Bali's Hindu culture, from Jakarta's megacity bustle to Papua's highland tribes, Indonesia's islands form a nation of staggering complexity and resilience.
