Giorgi IV Dadiani

George IV Dadiani (; died 1715) was Prince of Mingrelia from 1691 to 1704 and from 1710 to 1715. George's accession to rulership, following his ouster of the First House of Dadiani, inaugurated Mingrelia's second Dadiani dynasty, stemming from the House of Chikovani. George was also known as Lipartiani (ლიპარტიანი) by virtue of having Salipartiano as a fief from 1682 to 1715. George was actively involved in a series of civil wars that plagued the western Georgian polities. He was eventually deposed by his own son and placed under house arrest.

Rise to power George was a son of , the lord of Lechkhumi by his wife, Mzekhatun Dadiani, daughter of Prince Levan III Dadiani. Under Levan III Dadiani, Katsia attained to lordship of Salipartiano, a key fiefdom in Mingrelia, and exerted significant influence in the principality. George succeeded on Katsia's death as lord of Salipartiano in 1682. By placing Levan IV Dadiani, Levan III's natural son, on the throne of Mingrelia against the rival claims of George III Gurieli, Prince of Guria, in 1691, George became Mingrelia's de facto ruler. He embarked on a relentless campaign to eliminate any opposition to his authority by killings and harassment and enriched himself by slave-trading. In 1691, he forced Levan IV Dadiani to abdicate and made himself prince of Mingrelia, assuming the title and surname of Dadiani.

Civil war in Imereti George Dadiani attempted to make his positions more secure by forging an alliance with the Imeretian prince Giorgi-Malakia Abashidze, who usurped the crown of Imereti in 1702. Dadiani married Abashidze's daughter Tamar, having repudiating his earlier union with Princess Sevdia Mikeladze, the mother of his several children. Dadiani then proceeded, with the instigation of his new wife, to confiscate estates of the Mikeladze family, who lent support to Abashidze's arch-rival, George VI of Imereti. Amid ongoing power struggle, Dadiani's own brother Iese, lord of Lechkhumi, married to George VII's aunt Mariam, switched sides, but this cost him his possessions in 1703. In 1703, the Ottomans mounted a major expedition to consolidate their authority in western Georgia. Dadiani pledged loyalty to Abashidze and resisted an Ottoman force landed in Mingrelia. The principality held out, but Ottoman soldiers were left to garrison the maritime towns of Poti and Anaklia.
