Andrei Domanovsky's book "The Frankish Empire of Charlemagne" is a story about the wild unbridled tribes of the Franks and their wars with the Romans; on the creation by the cruel and cunning king Clovis of the Frankish kingdom; "lazy kings" of the Merovingian dynasty and powerful mayordoms, as well as land conquests, diplomacy and domestic politics of Charlemagne crowned by the imperial crown; about the achievements of the beautiful and majestic Carolingian Renaissance, which left a deep mark on European culture. The Frankish empire created by Charlemagne is rightly considered a kind of "European Union" of the Middle Ages. It was the power of Karl that became the historical basis not only of modern France, Germany and Italy, but also of many other neighboring countries.
