The relatively brief, but well-known Golden Age of Narnia (1000-1015), was initiated by the Battle of Beruna, and marked the end of the Long Winter, as predicted by the Golden Age Prophecy. During these fifteen Narnian years, Peter ruled as High King alongside his siblings, Queen Susan, King Edmund and Queen Lucy. The Merepeople Nation, Galma, Terebinthia, the Seven Isles and the Lone Islands were reintegrated into Narnia, and alliances were reforged with Archenland. The most notable war with Ettinsmoor was the Ettinsmoor War, led by the High King Peter, which also occurred in 1014.
