Demetrius of Anacopia ''. In 1033, the royal court faced another dynastic trouble, this time with Bagrat's half-brother
Demetrius of Anacopia, a son of George I of his second marriage with
Alda of Alania. Demetrius and Alda lived in
Anacopia, a fortress in
Abkhazia, which had been bequeathed to them by the late king George I. The efforts by Bagrat's mother
Mariam to win Demetrius's loyalty to the crown went in vain. Threatened by Bagrat, Alda defected to the
Byzantines and surrendered Anacopia to the emperor
Romanos III in 1033, who honored her son Demetrius with the rank of
magistros. According to
The Georgian Chronicles: King Bagrat defeated a united army of his opponents and then besieged Anacopia, then he went back, leaving Otago Chachasdze and his army to take charge of the fortress.
Liparit IV of Kldekari In 1038
Liparit IV, Duke of
Kldekari was on the verge of capturing the Georgian city of
Tbilisi, which had been under the
Muslim sway for centuries; but fearing his growing power the Georgian nobles thwarted the plan and persuaded the king to make peace with the
emir of Tbilisi. As a result, Liparit turned into a sworn enemy of Bagrat and began actively cooperating with foreign powers for vengeance. In 1039, he pledged his support to Bagrat's half-brother
Demetrius of Anacopia who returned to Georgia with a Byzantine army to seize the crown. Pretenders enjoyed numerous successes against the royal armies, despite their efforts to take a key fortress
Ateni went in vain, Liparit and the Byzantines won a major victory at the
Battle of Sasireti, where Bagrat suffered a crushing defeat and was forced to withdraw from his eastern possessions to take refuge in the western Georgian highlands. During the Seljuk campaigns in
Anatolia in 1048, Liparit, who had been fighting on the Byzantine side, was captured at the
Battle of Kapetron. Bagrat took advantage of this, and returned to his eastern possessions. The king's fortunes were quickly reversed, however, upon Liparit's return from captivity in 1049 or 1051. The rebellious duke forced Bagrat to flee to
Constantinople where he was kept, as a result of Liparit's intrigues, for three years. In the absence of Bagrat (1050–1053), Liparit was an effective ruler of Georgia; he even installed Bagrat's son
George II as king and declared himself a regent. After Bagrat's return in 1053, Liparit again warred against him. Eventually, in 1060, he was arrested by his followers and surrendered to the king, who forced him into a monastery under the name of Anton. Liparit died shortly thereafter at Constantinople and was reburied to his patrimonial monastery at
Katskhi in Georgia.
Peace The second half of the 11th century was marked by the strategically significant invasion of the
Seljuq Turks, who by the end of the 1040s had succeeded in building a vast empire including most of
Central Asia and
Persia. The Seljuk threat prompted the Georgian and Byzantine governments to seek a closer cooperation. To secure the alliance, Bagrat's daughter
Maria married, at some point between 1066 and 1071, to the Byzantine co-emperor
Michael VII Ducas. == Georgian expedition to Chaldia and the founding of the Trebizond Empire ==
