Biography
David IV, called Aghmashenebeli, "the Builder," transformed Georgia from a tribute-paying principality into the dominant power of the Caucasus. Born in 1073, the son of King George II of the Bagrationi dynasty, he came to the throne in 1089, at sixteen, when his father yielded power amid the devastation of Seljuk invasions and internal disorder. The young king set about restoring royal authority, curbing the great nobles, and rebuilding regions emptied by raids.
His reform of the Georgian church was an early priority. The Ruis-Urbnisi synod of 1103 deposed unworthy bishops and bound the church hierarchy more closely to the crown, while the office of chancellor was joined to a leading bishopric, uniting civil and ecclesiastical administration. In 1106 David founded the Gelati monastery near Kutaisi, which became the kingdom's principal center of learning. Militarily, he stopped paying tribute to the Seljuks, annexed Kakheti-Hereti in the east, and reorganized his forces, settling tens of thousands of Kipchak (Cuman) families from the steppe to provide a standing army loyal to the crown alone. His second marriage, to Gurandukht, daughter of the Kipchak chief Atraka, sealed that alliance.
The decisive test came on 12 August 1121, when a large Seljuk coalition assembled against Georgia was routed at Didgori, west of Tbilisi, in the most celebrated victory of Georgian history. The following year David took Tbilisi itself, under Muslim rule for some four centuries, and made it his capital, treating its Muslim population with a tolerance noted by contemporary Arab writers. In 1124 he extended his power over Shirvan and occupied the Armenian city of Ani at the request of its Christian inhabitants.
David tied his house to neighboring powers through his children: his daughter Tamar married the Shirvanshah Manuchihr III, while another daughter, Kata, was sent to Constantinople to marry into the imperial Komnenos family, opening the Bagrationi-Byzantine connection that later generations renewed. A man of learning who wrote the penitential Hymns of Repentance, David died on 24 January 1125 and was buried at Gelati. His son Demetrius I succeeded him, inheriting a kingdom that stretched across the Caucasus. The Georgian church canonized David as a saint.

Events
By the second decade of the twelfth century, David IV of Georgia had spent twenty years rebuilding his kingdom's army and clawing back territory from the Seljuk lordships that had dominated the Caucasus since the 1080s. He stopped paying tribute to the Seljuk sultanate, resettled tens of thousands of Kipchak nomad families from the north Caucasus steppe to serve as a standing military force, and pressed in on Tbilisi, which had been under Muslim rule for four centuries and was by then governed by its own urban elders under loose Seljuk protection. Appeals from Tbilisi and from neighboring Muslim rulers brought a response sanctioned by the Seljuk sultanate: a coalition army assembled under the Artuqid ruler Ilghazi of Mardin, a commander with a recent and considerable reputation, joined by forces from Shirvan and other regional powers. Medieval figures for its size are not credible, but it substantially outnumbered the Georgian army, which contemporary sources place at several tens of thousands, including the Kipchak corps and a small contingent of Western knights. On 12 August 1121 David met the coalition in the narrow valleys at Didgori, west of Tbilisi, where broken ground prevented the larger army from deploying its numbers. The Georgian attack broke the coalition's order early in the engagement, and the battle became a pursuit; Georgian tradition remembers it as the "miraculous victory." The strategic results were immediate and durable. David took Tbilisi the following year and moved his capital there, ending Seljuk power north of the Araxes, and the battle marks the opening of Georgia's golden age, in which the Bagrationi monarchy stood as the dominant power of the Caucasus for the next century.
