Grand Duchy of Klettoria

The Grand Duchy of Klettoria or the Duchy of Klettoria Magna (Khijovian: Klaettœrïænnə Grænnđucþə)

In 1152, the now Grand Duchy of Klettoria began its expansionist campaign with the aim of unifying Khijovia into single kingdom under the leadership of the Grand Duke Zenon the Great, who easily conquered and subdued numerous independent states of north-western Khijovia until ultimately clashing with the rival House of Arenia starting from 1155. Despite heavy losses, Zenon the Great managed to defeat the opposing army in the Battle of Pronia (October 12, 1156) and to force the retreat of the Arenian House to the island of Axiomia, where they remained in exile for years while Zenon continued his conquest campaign in the rest of Khijovia. After annexing a large part of the remaining Khijovian territory, only the Grand Duchy of Axiomia remained to be conquered: following months of assiduous siege, Axiomia eventually fell into the hands of the Zenonian army and, a year before his death, Zenon the Great proclaimed the birth of the Kingdom of Khijovia in the capital city of Kleitore on July 11, 1161.
