Second Triarchy

The Second Triarchy was a union of the Free Cities of Myr, Tyrosh and Lys, formed in 303 AC following Myr's conquest of the latter two. It considered itself the successor state to the original Triarchy, a voluntary alliance of the three city-states that existed from 96 AC until 131 AC. Originally formed to oppose Daenerys Targaryen and her efforts to emancipate slavery, the Second Triarchy soon developed ambitions to invade and essentially colonise the Seven Kingdoms after much of it was left devastated by the Great War. After courting a coalition of allies (collectively known as the Eastern Coalition), the Second Triarchy invaded Westeros in 309 AC, sparking the War of the Narrow Sea. Despite initial success, the war turned and ultimately ended in defeat, and the Second Triarchy was occupied by Westerosi forces, before being dissolved and reorganised into a de-facto satellite state of the New Throne; the Three Daughters Protectorate.
