However, after the enthronement of Abaqa as the Il-Khan, Sadun received the titles of atabegi (or regent) and amir-spasarali (or commander in chief), and gained administrative E power over the Batratid Kingdom. He was entrusted by the Kings with the power to control the royal domains of T'elavi, Belakani and Kars. In addition, he purchased the district of Dmanisi from King Dimitri II. Together, Sadun's estates made up the fourth political unit in Georgian Armenia in addition to the three units belonging to the branch families of the Zak'areans. we can assume that he was able to acquire wealth because he was a･ t'arkhan, ･his After Sadtm's death in 1282, one bf two titles, the amir- spasarali was given to his son Khutlu-Bugha, but the other, the atabegi was given to his rival Tarsayichi of the house of Orbelean. In 1289, Khutlu-Bugha recommended that rl-Khan Arghun kill King Dimitri (who had been arrested for being implicated in the plot of Bugha) and put･Vakhtangi, the son of King Daviti IV on the throne. His plan succeeded. Under Vakhtangi, Khutlu-Bugha be- came both the atabegi and the amir-sPasarali and secured political ' power over the Georgian Kingdom. In 1292, however, both Arghun and Vakhtangi died. As soori as Daviti, the son of Dimitri, ascended to the throne, Khutlu- Bugha was put to death by the order of the new khan Geikhatu. With his death, the power of the Artsrunis was eradicated froni the entire Bagratid territory. The rise of Sadun Artsruni is a good example illustrating the pattern of socio-political control the Il-Khans had over the native dynasties. The il-Khans' system of appointments as kings, vassals or arriere-vassals, of those who were faithful and useful to them, had worked effectively. They ruled over the Bagratid territory mp=Re- through the kingship, which was never handed outside the royal family of Bagratid and through the offices of the atabegi and the amir-spasarali. These latter were not confined to any one family, but were easily given to those, like Sadun, who were useful to the Il-Khans.

The Rise of the Artsrunis and the rl-Kha-nid Rule over Georgia by Sei-ichi' Kitagnwa This is a study of the role Sadun of the house of Artsruni and his son Khutlu-Bugha played in the expansion of the Il-Khanid･ rule over the Georgian Kingdom in the 13th century. Sadun was a great grandson of Amir K'urd (Abulasan), the governor of Tbilisi during Queen Tamar's reign in Georgia. In 1258 (or 1259), he won a wrestling match in the presence of Hulegu Khan and receivdd the honorable status of t'arfehan. He joined Hulegu's J Syrian campaign, which began in'the autumn of 1259 and was placed in the vanguard. He distinguished himseif during the conquest of Sasun and the seizure of the citadel of Allepo. For these services, Sadun was awarded with an oMcial commendation from Hulegu and Ea9e' was granted the district of Sasun. Sadun-was originally a vassal of Avag Zak'arean, a Georgian King's prince (eristavi, or ishlelaan in Armenian), and a seignior of Haghbat and Mahkanaberd. Around the time of the above promo- tions, he Was an at'abale of Avag's heiress Khoshak but later, he became her chamberlain or khej'ub to guard and assist her. Under Hulegu, Sadun was never given any oMcial titles of the NII-Electronic Library Service The HistoricalSocietyHistorical Society of Japan MediterraneanWorld and the Roman Empire : ' -by . 7brtz Yzage (This paper is based on the lecture whichIgave at the annual general meeting of SHIGAKU-KAI, The Historical Soc'iety of Japan, { held on the 5th November 1977 at the University of Tokyo.') "Mediterranean In what sense can one speak of the World" "world" in antiquity? What does mean, when one speaks of the "Mediterranean World"?
