David X (Georgian: დავით X, Davit X) (1482–1526) was a king of the Georgian kingdom of Kartli from 1505 to 1525.
He was the eldest son of Constantine II, whom he succeeded as king of Kartli in 1505 1. Despite the fact that Constantine had recognised the independence of the breakaway Georgian kingdoms of Imereti and Kakheti, the rivalry among these polities was to continue under David. He had to defend his kingdom against the attacks by Alexander II of Imereti in the west, and George II of Kakheti in the east. In August 1509, Alexander took a fort-city Gori and the northwestern corner of Kartli, but had to abandon the occupied lands to David due to the Ottoman raid on Imereti in 1510. A year later, George of Kakheti surged into Kartli, but failed to capture the king in a besieged castle of Ateni. In 1513, George invaded again, only to be defeated and taken prisoner by David’s younger brother Bagrat I of Mukhrani. He died in captivity and his kingdom was annexed to Kartli. In 1518, the Persian shah Ismail I of the newly established Safavid dynasty, sent in an army under Div Sultan Rumlu, who was joined by the Georgian prince Qvarqvare III Jakeli, atabeg of Samtskhe. The invaders occupied Surami and Gori, and David had to make peace with the Persians and to promise to pay tribute. Meanwhile, the Kakhetian nobles used the opportunity to install Levan, son of the late king George II, as their king. David besieged the Maghrani Castle where Levan had taken positions, but soon had to abandon the siege as the Turkomans appeared again in the Georgian lands. David recognised Lavan as the king of Kakheti in order to win his support against the invaders. In 1522, he refused to convert to Islam as Shah Ismail had demanded. A new Persian invasion ensued, led this time personally by the shah. David and his son, Luarsab I, offered him a fierce resistance at the Battle of Teleti, but were finally outnumbered and defeated. The Kartlian capital Tbilisi was taken by treachery and garrisoned by a large Persian force. On the death of Ismail in 1524, David liberated Tbilisi and expelled the Persians from the country. In 1525, he reconquered Aghjakala, Lower Kartli, and massacred all the Turkomans who had settled there. The same year, he abdicated the throne in favor of his younger brother, George IX, and retired to a monastery under the name of Damiane.
David X died in 1526 and was buried at the Svetitskhoveli Cathedral at Mtskheta. He was survived by three sons:
| Preceded by Constantine II |
King of Kartli 1505-1525 |
Succeeded by George IX |
