The Latin Christian kingdoms wedged between German-speaking Central Europe and the steppe: crowned from Rome rather than Constantinople, spending centuries absorbing whatever rode out of the east — Mongols, Tatars, Ottomans — on ground the rest of Latin Christendom was content to let them hold alone.

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 The Tsardom and Empire of Russia. 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.
