This is a list of the Diadochian monarchs from the founding of Diadochia in 2580 BC by the legendary Emperor Kronos I. The Diadochian Emperor is known by verious titles and styles including, Emperor (Autokrator), Sovereign/King (Basileus), Augustus, Kaiser and various others. The Diadochian monarchy is by far the oldest continuous monarchy in Pandos, being over four thousand years old. Almost every royal house of Diadochia has been able to trace its line to the original Kronid-Atlantean emperors of old.
