Principality of Iberia in the context of "Bagrationi dynasty"

The Kingdom of the Iberians (Georgian: ქართველთა სამეფო, romanized: kartvelta samepo) was a medieval Georgian monarchy under the Bagrationi dynasty which emerged circa 888 AD, succeeding the Principality of Iberia, in historical region of Tao-Klarjeti, or upper Iberia in north-eastern Turkey as well parts of modern southwestern Georgia, that stretched from the Iberian gates in the south and to the Lesser Caucasus in the north.

Historically, the area comprised the following historical districts: West of the Arsiani Mountains were Tao, Klarjeti, Nigali, and Shavsheti, to the east lay Meskheti, Erusheti, Javakheti, Artaani, Abotsi, Kola and Basiani. The landscape is characterised by mountains and the river-systems of the Çoruh and the Kura. The region played a crucial role in the unification of all Georgian lands and principalities into the Kingdom of Georgia in 1008.

Arminiya, also known as the Ostikanate of Arminiya or the Emirate of Armenia (Arabic: إمارة أرمينية, imārat armīniya), was a political and geographic designation given by the Muslim Arabs to the lands of Greater Armenia, Caucasian Iberia, and Caucasian Albania, following their conquest of these regions in the 7th century. Though the caliphs initially permitted an Armenian prince to represent the province of Arminiya in exchange for tribute and the Armenians' loyalty during times of war, Caliph Abd al-Malik ibn Marwan introduced direct Arab rule of the region, headed by a governor known as the ostikan with his capital in Dvin.

Sasanian Iberia (Georgian: სასანური ქართლი, romanized: sasanuri kartli; Middle Persian: 𐭥𐭫𐭥𐭰𐭠𐭭, wirōzān/wiruzān/wiručān) was the period the Kingdom of Iberia (Kartli, eastern Georgia) was under the suzerainty of the Sasanian Empire. The period includes when it was ruled by Marzbans (governors) appointed by the Sasanid Iranian king, and later through the Principality of Iberia.

The Bagrationi dynasty (/bʌɡrʌtiˈɒni/; Georgian: ბაგრატიონი, romanized: bagrat'ioni [ˈbäɡɾätʼio̞n̪i]) is a royal dynasty which reigned in Georgia from the Middle Ages until the early 19th century, being among the oldest extant Christian ruling dynasties in the world. In modern usage, the name of the dynasty is sometimes Hellenized and referred to as the Georgian Bagratids, also known in English as the Bagrations. Originally comes from the Armenian Bagratuni dynasty.

The origins of the dynasty are disputed. Most scholars agree that the dynasty comes from the Armenian Bagratuni dynasty, and is seen as a smaller branch of the Bagratids. The early Georgian Bagratids gained the Principality of Iberia through dynastic marriage after succeeding the Chosroid dynasty at the end of the 8th century. In 888 Adarnase IV of Iberia restored the Georgian monarchy; various native polities then united into the Kingdom of Georgia, which prospered from the 11th to the 13th century. This period of time, particularly the reigns of David IV the Builder (1089–1125) and of his great-granddaughter Tamar the Great (1184–1213) inaugurated the Georgian Golden Age in the history of Georgia.
