For most their existence of the Kaysite state, the amirs recognized their stronger neighbors as suzerains, though often these declarations were only nominal and in effect the Kaysites were independent. When Abu'l-Ward took control of Apahunik', the
ostikanate of Arminiya was still extant. As a result, Abu'l-Ward, as with all the other Arab and Armenian rulers in Armenia, were subject to the caliph's
ostikans. The
ostikans served as protectors of the Kaysites, and relations between them were overall friendly. When a pan-Arab coalition led by the
ostikans against the increasingly powerful Christian princes of Armenia in the late 870s was formed, Abu'l-Ward was one of its most powerful members. The ultimate failure of the coalition against the Christian Armenians foreshadowed the end of the Arminiyan
ostikanate in the next decade. In place of the
ostikans, in 885 the caliph
al-Mu'tamid (870–892) sent a crown to the
Bagratid prince
Ashot I, thereby restoring the
Kingdom of Armenia. This move made the Kaysites subject to Ashot, who Abu'l-Ward was on bad terms with. By the late 890s the reigns of both Ashot and Abu'l-Ward were at an end; Ashot was succeeded by his son
Smbat I (890–912) while Abu'l-Ward's three grandsons eventually assumed power. When Smbat I fell into difficulties early in his reign Abu'l-Ward's grandsons revolted against his authority but were defeated in battle. They were forced to resume paying tribute to the king and to send hostages. Smbat I was murdered by the
Sajid amir of
Azerbaijan in 912 and was eventually succeeded by his son
Ashot II (914–928). During the civil war following Smbat's death the Kaysites ceased to recognize the suzerainty of the Bagratids. At the same time, however, the
Byzantine Empire became active in Armenian affairs. The proximity of the Byzantines compelled the three grandsons of Abu'l-Ward to begin forwarding tribute to the Empire. Other than the tribute, Byzantine authority over the Kaysites was restricted, although periodic raids by them into Kaysite territory are recorded. In 940 the
Hamdanid amir
Sayf al-Daula came to
Ahlat, where the Kaysite amirs pledged allegiance to him. From this point on the Kaysites were Hamdanid vassals, and remained so until the end of their rule in 964. ==Kaysite rulers==
