Hoster Tully is Lord of Riverrun at the onset of the GoT series. Once Robert’s Rebellion had begun and the rebels raised their banners, Hoster Tully married Catelyn to Ned and Lysa to Jon Arryn, forming a powerful alliance between House Tully, Stark and Arryn, as well as House Baratheon.Įdmyn Tullywas the first Tully overlord of the Riverlands, after pledging fealty to Aegon during his Conquest. He next arranged for Catelyn to be wed to Brandon Stark, but that proved unsuccessful as well, as Brandon was killed by the Mad King, one of the causes of Robert’s Rebellion. Lord Tywin offered Tyrion as replacement, but Lord Hoster Tully refused. Lord Hoster Tully first arranged for Catelyn to marry Jaime Lannister, prior to his appointment to the Kingsguard. In more recent years, House Tully has arranged strategic marriages in an effort to form powerful alliances, in light of the fact that they are vulnerable to attack from regions on all sides.

As reward for pledging their fealty to Aegon, House Tully was appointed overlords of the Riverlands. However, on the day it was completed, Harren the Black and his entire bloodline was wiped out, as Aegon flew over the walls of Harennhal and scorched it with his dragon. To solidify the stretch of his kingdom from the Iron Islands to the Riverlands, he built the greatest castle that Westeros had ever seen, Harrenhal, which took 40 years to build. At the time, Haren the Black, King of the Iron Islands, had asserted his dominance over the Riverlands. House Tully solidified its power within the Riverlands when Lord Edmyn Tully pledged his allegiance to Aegon during the Conquest.

As such, the Tullys never ruled as kings since the Riverlands were never one of the Seven Kingdoms. However, after the Andal Invasion, when Westeros began forming its Seven Kingdoms, the Riverlands were conquered by the Iron Islands, and thus never formed its own kingdom. House Tully has been a powerful house of the Riverlands for thousands of years.
