But the Armenian courage and national spirit, and the political and military ability which had governed the Eastern Empire so many centuries, were not extinct. The heart of the nation, forced out of its immemorial lands, still beat strongly, and animated their mass of dukedoms, now forming a compact body in the center of Asia Minor, with a common life and national instinct, which was soon to weld them into a new Armenian kingdom, as true and real a one as the old, Armenians under an Armenian prince, but in a wholly different territory, south and southwest of the former. Among the great barons of this district was one Rupen (Reuben), a relative of the slain Kakig; it is said that he saw him hanged. At any rate, no sooner was the deed accomplished than he retired to the mountains of Northeastern Cilicia, and raised the standard of Armenian independence, with himself as king. There was absolutely no reason why it should not be gained; the Seljuk conquests had cut the Armenian districts wholly off from the Greek Empire, so that a Greek army could not come upon them to punish them for revolt without traversing at least a hundred miles of Turkish or other Mohammedan territory. The Armenian settlements were an island in a sea of Mohammedanism. The new kingdom of Cilicia or Lesser Armenia grew with a rapidity that would seem miraculous, only it was a mere coalescing of the fragments of Armenia into their old unity; in no long time it had spread east to the Euphrates, taking in Melitene (Malatia), and Samosata, north fully half way to the Black Sea, and south to the Mediterranean, occupying the coast from Tarsus almost to Antioch. This kingdom played a part of the first importance in the history of Asia Minor for close on three centuries; its territories were gradually whittled away by Turks and Mongols, but it kept the Eastern Mediterranean open for Christian action against the Mohammedans to the last. To their shame, the Byzantine emperors were much more hostile to it than to the Turks, with whom they often allied themselves against it; for some years it was vassal to the Byzantine Empire; later it was overwhelmed by the Mameluke deluge from Egypt, and allied itself with Jenghiz Khan's Mongol hordes against them; but the Mongols passed and the Mamelukes remained, and exacted a terrible vengeance, putting an end to the kingdom with the usual horrors of Oriental conquest in 1375.
