Yang Kil (Korean: 양길; Hanja: 梁吉) was a head of rebel forces in Silla.
In 889, the state coffers of Silla were empty, so the queen sent envoys to the provinces to press her subjects into paying taxes.
[1] The extent of Yang Kil's power is uncertain, but it is thought to have been considerable given the fact that Kung Ye was among his men.
According to the Samguk Sagi, Kung Ye's army's strength reached about 600 men, who are believed to have been soldiers given to him by Yang Kil.
Once Kung Ye's power had increased, he left Yang Kil's army and founded Later Goguryeo.
