Rule of the Dukes
The Rule of the Dukes was an interregnum in the Lombard Kingdom of Italy (574/5–584/5) during which part of Italy was ruled by the Lombard dukes of the old Roman provinces and urban centres. The interregnum is said to have lasted a decade according to Paul the Deacon, but all other sources—the Fredegarii Chronicon, the Origo Gentis Langobardorum, the Chronicon Gothanum, and the Copenhagen continuator of Prosper Tiro—accord it twelve years.
