Europe's history is littered with kingdoms, duchies, empires and republics which have now disappeared but which were once fixtures on the map of their age. What happened to the once-great Mediterranean 'Empire of Aragon'? Where did the half-forgotten kingdoms of Burgundy go? Which current nations will one day become a distant memory too? This original and enthralling book peers through the cracks of history to discover the stories of lost realms across the centuries.
