Also reminds me of how Germany states are still bankrolling bishops in compensation of taking territories from their predecessors shortly before the original HRE collapsed to Napoleonic pressure. Survived three collapsing empires, two republics (GDR also paid up) and half a dozen or so decades of independent states honoring those obligations. A plan for buying out is on the books since the Weimar constitution (and explicitly honored in the Grundgesetz), but nobody seems to be in a particular hurry...
