China

The longest continuous imperial tradition anywhere, and the argument about whether it is one state seen many times or many states using one name. Every dynasty here inherited a bureaucracy, a script and a claim to a mandate that could be lost — including the ones that arrived from the steppe and governed two populations under two administrations.

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.

9 sourced edges run between this region and another, to Mongol Empire, Northern Yuan, Qara Khitai, Gojoseon (Old Joseon), Goguryeo, Baekje and Balhae. 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.
