Tarth is an island in the narrow sea off the eastern coast of Westeros. It is separated from the continent by the Straits of Tarth, and is situated northeast of Shipbreaker Bay. Tarth is considered a part of the stormlands and is ruled from Evenfall Hall by House Tarth. It is sworn to Storm's End.
The island is said to be very beautiful, "with its mountains and waterfalls, its high meadows and shadowed vales." It is called the Sapphire Isle for the striking blue seas in which it sits.
Maesters believe that the great island kingdom of Tarth joined the realm of the Storm Kings when King Durran the Fair married the daughter of the island's king, Edwyn Evenstar. The island rebelled three times during the reign of the Storm King Durwald the Fat, however.
Tarth was the first region of House Durrandon's Kingdom of the Storm to be conquered by Andals during the Andal invasion. The Durrandon Storm Kings and their First Men bannermen eventually intermarried with the Andals, however. House Tarth, who rule the island from Evenfall Hall and were once kings, have Andal ancestry.
Now in ruins, Morne on the eastern coast of Tarth was once the seat of petty kings who were conquered by Storm Kings. Maester Hubert believes the site was of Andal origin, not First Men. Nobles and smallfolk alike from Tarth claim descent from Ser Galladon of Morne.

To prevent Brienne of Tarth from being raped, Ser Jaime Lannister misleads the Brave Companions into believing that Tarth is known as the Sapphire Isle because of an abundance of gemstones. In actuality, the name comes from the color of its waters. Vargo Hoat rejects Selwyn's offer of three hundred golden dragons to ransom his daughter Brienne, as Vargo demands sapphires.
