Aegon I Targaryen, King of the Seven Kingdoms

From Asoiaf

Aegon I of House Targaryen, called the Dragon and the Conquerer, was the first king of the Seven Kingdoms (reigned 1 AL - 37 AL).

Aegon sailed from Dragonstone with his sisters Visenya Targaryen and Rhaenys Targaryen to conquer the Seven Kingdoms during the Wars of Conquest.

Aegon granted Storm's End to his rumored bastard brother, Orys Baratheon, after he had defeated and slain Argilac the Arrogant, the last of the Storm Kings.

Harren the Black, King of the Isles also ruled the riverlands, however he was not well loved and many of the river lords deserted him, first amongst them Edmyn Tully, Lord of Riverrun. Harren and his line perished in the burning of Harrenhal. Afterwards Aegon granted Edmyn Tully dominion of the lands of the Trident. He allowed the surviving iron lords to chose who should have the primacy among them. They chose Vickon Greyjoy, Lord of Pyke as Lord of the Iron Islands.

The last King in the North, Torrhen Stark, known as the King Who Knelt, chose to swear fealty to Aegon rather than do battle. He therefore kept his land and continued to rule as Lord of Winterfell.

The last King of the Reach, King Mern, perished at the Field of Fire. His steward, Harlen Tyrell, surrendered Highgarden to Aegon. As reward Aegon gave him Highgarden and dominion of the Reach.

Aegon married both his sister. With Rhaenys he had Aenys I and with Visenya Maegor I.

On his death Aegon I was succeeded by Aenys I.
