Battle of Didgori

The Battle of Didgori (Georgian: დიდგორის ბრძოლა) was fought between the armies of the Kingdom of Georgia and the declining Great Seljuq Empire at the place of Didgori, 40 km west of Tbilisi, (the modern-day capital of Georgia), on August 12, 1121. The battle resulted in King David IV of Georgia’s decisive victory over a Seljuk invasion army under Ilghazi and the subsequent reconquest of a Muslim-held Tbilisi, which became the royal capital. The victory at Didgori inaugurated the medieval Georgian Golden Age and is celebrated in the Georgian chronicles as a "miraculous victory" (ძლევაჲ საკვირველი, dzlevay sakvirveli). Modern Georgians continue to remember the event as an annual September festival known as Didgoroba ("[the day] of Didgori").
