David X (Georgian: დავით X) (c. 1470s or 1480s –1526) was the second king (mepe) of the Kingdom of Kartli from 1505 to 1525. Associated with the throne as a child, he became king on the death of his father and from then on had to endure invasions from the Kingdom of Imereti and Kingdom of Kakheti. A reformer, he succeeded in subduing the army and destroying the power of the nobles by abolishing the semi-independent principalities that were ruining the unity of the country, before uniting eastern Georgia under a single scepter. David X is also known to have survived another invasion by Persia, and is thus considered to be the first in a series of eleven kings who fought against their Safavid neighbors over the next two centuries.
