Iulon, son of Heraclius II of Georgia

Iulon (Georgian: იულონი; 4 June 1760 – 23 October 1816) was a Georgian royal prince (batonishvili) of the House of Bagrationi, born into the family of King Heraclius II and Queen Darejan Dadiani. He advanced claim to the throne of Kartli and Kakheti after the death of his half-brother George XII in 1800 and opposed the Russian annexation of Georgia until being apprehended and deported in 1805 to Tula. He died in St. Petersburg and was buried at the Alexander Nevsky Lavra.

Iulon was a son of Heraclius II of his third marriage to Darejan (Daria) née Dadiani, born at the royal castle of Telavi in 1760. In September 1787, Iulon, together with Prince Orbeliani, commanded a 4,000-strong Georgian force sent by Heraclius against his former ally Ibrahim, khan of Karabakh. The Georgians were victorious, but the sudden withdrawal of an allied Russian army from the Caucasus rendered further operations abortive.

In 1790, Iulon received a princely domain in the Ksani valley after Heraclius II dispossessed the defiant Kvenipneveli dynasty of the duchy of Ksani, dividing it into three parts. Other parts of the duchy were granted to Iulon's half-nephews, Ioane and Bagrat, sons of Crown Prince George, the future King George XII. In addition, in 1794, Iulon was placed in charge of the province of Kartli. At the time of an invasion by the Iranian army of Agha Muhammad Khan in 1795, he was headquartered at Gori and did not take part in fighting which devastated Heraclius's capital, Tbilisi.
