The Red Wedding was a massacre that took place during the War of the Five Kings in the HBO series Game of Thrones. It occurred at the wedding feast of Edmure Tully, Lord of Riverrun, and Roslin Frey at the Twins in 299 AC. The events of the Red Wedding were orchestrated by Lord Walder Frey, who had been slighted by Robb Starks breaking of a marriage pact with one of his daughters. The key events of the Red Wedding are:

• The Massacre: During the wedding feast, the Freys and Boltons slaughter Robb Stark, his mother Catelyn Stark, his wife Talisa, and many of his bannermen.

• The Rains of Castamere: This is the song played by the band at the beginning of the massacre. It is also the title of the episode in which the Red Wedding occurs.

• Guest Right: The Red Wedding stains the ancient custom of guest right, with safety and security in anothers home no longer being considered guaranteed.

The Red Wedding was a shocking event that saw the deaths of dozens of minor and major characters. It dealt a blow to House Stark, but Arya Stark avenges her family by destroying House Frey at the beginning of Game of Thrones season 7, episode 1, "Dragonstone". The massacre ruins House Freys reputation, and they are treated with antipathy and disgust by many Westerosi, including their own allies.
