Aegon's Conquest - 1 AC

Aegon I Targaryen, also known as Aegon the Conqueror and Aegon the Dragon, was the first Lord of the Seven Kingdoms and king on the Iron Throne, having conquered six of the Seven Kingdoms during the Conquest. He was the founder of the ruling Targaryen dynasty of Westeros.

When Aegon was ready, he and his two sister-wives, Rhaenys and Visenya, landed with his army on the east coast of Westeros at the mouth of the Blackwater Rush, where he constructed the wooden Aegonfort after Aegon's Landing. With the aid of their three dragons (Vhagar, Meraxes, and Balerion the Black Dread), Aegon led the Targaryen army to victory after victory, including his first test near the Blackwater, the burning of Harrenhal, and the Field of Fire.
