I'm adding a poll based on what I've heard, if I missed anything, feel free to post it. I AM NOT adding STATES like Australia, Brazil, Mexico, Argentina, South Africa, or Indonesia. We've had this debate before, these are states, not civilizations, not unique cultures, some debatebly not even nations. The closest thing to a modern day state with a unique culture is actually Brazil, but even then, you're on shaky ground. No one cares about GDP, standard of living, or what your nation did from 1990 onward. This is civilization, not nation state.
EDIT: Consider Majapahit under Srivijaya.
