It is known that in 974 he participated in the mobilization of Armenian troops initiated by his father Ashot III, during the time of Byzantine Emperor John Tzimiskes' campaign in Asia Minor, which posed a threat to the southern borders of Armenia.

[1] Kiurike received the title of "King of Tashir-Dzoraget", in the northern part of the Bagratid Kingdom of Armenia, after the death of his father in 977.

Described as an extremely devout man, he abdicated the throne of in favor of his son David I and devoted the last 8 years of his life to spiritual matters at Sanahin Monastery.

[4] As a result of his successful wars against the neighboring emirates of Tiflis (Tbilisi) and Ganja, David significantly expanded the boundaries of his kingdom.

[5] In the mid-990s, he annexed Dmanisi, defeated the emir of Tiflis Ali ibn Jafar in battle and forced the latter to accept the Kiurikians' suzerainty.

David, though unable to build on this victory and expand the boundaries of his kingdom, temporarily eliminated the threat posed by the Emir of Ganja.

The latter renounced the Armenian Church and converted to Chalcedonism, apparently with the aim of enlisting the support of Georgia and gaining independence from the Kiurikids.

[3] In 1001, David made an unsuccessful attempt to achieve complete independence from the Bagratid Kingdom of Armenia, which was brutally suppressed by his uncle King Gagik I.

[3] In the first years of the reign of the Georgian king Bagrat IV (1027–1072), the Emir of Ganja Fadlun I made an attempt to seize the entire territory of the Kura river valley, including the city of Tifilis.

Around 1029/1038, Gagik ascended to the throne, founding a new branch of the Kiurikid dynasty, who ruled the united kingdom of Kakheti and Hereti until 1105, when these lands were conquered by Georgia.

As a result, when the Shaddadid Emir of Dvin Abu'l-Aswar invaded Tashir-Dzoraget with a large army in 1040 and captured a significant part of the kingdom within a year, Bagrat IV did not rush to the aid of David the Landless.

During the campaign of Alp Arslan against Bagrat IV, Kiurikie II and his nephew, the king of Kakheti-Hereti Aghsartan I, and the Emir of Tiflis participated on the side of the sultan.

In 1118, the lands of the Tashir-Dzoraget kingdom were annexed to Georgia by David the Builder, after which the Kiurikians, entrenched in the fortresses of Matsnaberd and Tavush, retained their royal title until the beginning of the 13th century.
