Yongle Emperor
On 1 April 1424, the Yongle Emperor launched a large campaign into the Gobi Desert to chase an army of fleeing Oirats. Frustrated at his inability to catch up with his swift opponents, Yongle fell into a deep depression and then into illness, possibly owing to a series of minor strokes. On 12 August 1424, the Yongle Emperor died. He was entombed in Changling (), a location northwest of Beijing.
