Sumatra and the Peninsula

The strait, and the states that lived on it: a thousand years of one passage between the Indian Ocean and the South China Sea changing hands, from Srivijaya to the sultanates that inherited its position and its sea peoples.

The line below is a time axis. Position on it is date, so concurrency is visible: concurrent polities sit side by side rather than in sequence.

1 sourced edge runs between this region and another, to Singhasari. Those are not drawn on this line — a thread that crossed regions would assert a sequence nobody cited — but they are on each polity’s own page.
