There are nine Great Houses in Westeros. When the show began, they were Stark, Arryn, Baratheon, Tully, Greyjoy, Lannister, Tyrell, Martell and Targaryen. As of Game of Thrones houses Season 6, Daenerys is the only surviving Targaryen and remains in exile. House Stark and House Tully have also been displaced, their lands taken away from them, but both Houses survive—at least for now.
