Early reign and first marriage

For six years, Tamar was a co-ruler with her father upon whose death, in 1184, Tamar continued as the sole monarch and was crowned a second time at the Gelati cathedral near Kutaisi, western Georgia. She inherited a relatively strong kingdom, but the centrifugal tendencies fostered by the great nobles were far from being quelled. There was considerable opposition to Tamar's succession; this was sparked by a reaction against the repressive policies of her father and encouraged by the new sovereign's other perceived weakness, her sex. As Georgia had never previously had a female ruler, a part of the aristocracy questioned Tamar's legitimacy, while others tried to exploit her youth and supposed weakness to assert greater autonomy for themselves. The energetic involvement of Tamar's influential aunt Rusudan and the Catholicos-Patriarch Michael IV was crucial for legitimizing Tamar's succession to the throne. However, the young queen was forced into making significant concessions to the aristocracy. She had to reward the Catholicos-Patriarch Michael's support by making him a chancellor, thus placing him at the top of both the clerical and secular hierarchies.

Tamar was also pressured into dismissing her father's appointees, among them the constable Kubasar, a Georgian Kipchak of ignoble birth, who had helped George III in his crackdown on the defiant nobility. One of the few untitled servitors of George III to escape this fate was the treasurer Qutlu Arslan who now led a group of nobles and wealthy citizens in a struggle to limit the royal authority by creating a new council, karavi, whose members would alone deliberate and decide policy. This attempt at "feudal constitutionalism " was rendered abortive when Tamar had Qutlu Arslan arrested and his supporters were inveigled into submission. Yet, Tamar's first moves to reduce the power of the aristocratic élite were unsuccessful. She failed in her attempt to use a church synod to dismiss the Catholicos-Patriarch Michael, and the noble council, Darbazi, asserted the right to approve royal decrees.

Queen Tamar's marriage was a question of state-importance. Pursuant to dynastic imperatives and the ethos of the time, the nobles required Tamar to marry in order to have a leader for the army and to provide an heir to the throne. Every group strove to select and secure the acceptance of its candidate in order to strengthen its position and influence at court. Two main factions fought for the influence in Tamar's court: the clans of Mkhargrdzeli and Abulasan. The faction of the Abulasan won, the choice was approved by Tamar's aunt Rusudan and council of feudal lords. Their choice fell on Yuri, son of the murdered prince Andrei I Bogolyubsky of Vladimir-Suzdal, who later lived as a refugee among the Kipchaks of the North Caucasus. They called an influential person in the kingdom, the great merchant Zankan Zorababeli. He was given the mission of bringing the bridegroom to Tbilisi. He fulfilled his mission with zeal, and the prince was brought to Georgia to marry the queen in 1185.

The young man – valiant, perfect of body and pleasant to behold – Yuri proved to be an able soldier, but a difficult person and he soon ran afoul of his wife. The strained spousal relations paralleled a factional struggle at the royal court in which Tamar was becoming more and more assertive of her rights as a queen regnant. The turning point in Tamar's fortunes came with the death of the powerful Catholicos-Patriarch Michael whom the queen replaced, as a chancellor, with her supporter, Anton Gnolistavisdze. Tamar gradually expanded her own power-base and elevated her loyal nobles to high positions at the court, most notably the Mkhargrdzeli.
