Goguryeo, surrounded by the powerful forces of Baekje to its south and west, is therefore inclined to avoid conflict with its peninsular neighbor while cultivating constructive relations with the Xianbei and Rouran in order to defend itself from future invasions, and even the possible destruction of its state.

Gwanggaeto succeeds his father, King Gogukyang, upon his death in 391.

Immediately upon being crowned king of Goguryeo, Gwanggaeto grants himself the title Emperor Yeongnak, affirming himself as equal to the rulers of China and the king of Baekje.

He now begins to rebuild and retrain Goguryeo's cavalry units and naval fleet.
