Before the Targaryen conquest, the Riverlands were ruled by the ironborn. Aegon the Conqueror's assault was assisted by an uprising held by House Tully. Therefore, House Tully have ruled as the Lords of Riverrun ever since the conquest.
The title is held by Hoster Tully until his death of natural causes at the height of the War of the Five Kings. He was succeeded by his only son, Edmure Tully. As Edmure was unmarried at the time of Hoster's death, Catelyn Stark and Lysa Arryn were the heirs to Riverrun until a child would be born to Edmure through his arranged marriage with Roslin Frey.
Following the Red Wedding, Walder Frey imprisons Edmure and kills Catelyn, but their uncle Brynden "The Blackfish" Tully escapes and heads back to Riverrun. Walder Frey gloats that Tywin Lannister intends to reward him for the betrayal by making a Frey the new Lord of Riverrun, but it is unknown if Brynden and the surviving Tully garrison at Riverrun will accept this without a fight.
