Iberia

A peninsula reconquered piecemeal, over seven centuries, by Christian kingdoms that spent as much of that time fighting each other as fighting the Muslim south - and that went on, the moment the reconquest was finished, to launch the first colonial empires with a global reach.

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.

2 sourced edges run between this region and another, to Sultanate of Melaka and Mutapa Empire. 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.
