The Song conquest of Northern Han (Chinese: 宋滅北漢之戰) occurred in 979, when Northern Song forces captured the Northern Han capital of Taiyuan in present-day Shanxi Province after a two-month siege.
A relief attempt by forces of the Liao dynasty, which was allied to the Northern Han, was easily defeated by the Northern Song.
Yelü Dilie, a cousin of the Emperor Jingzong of Liao, was killed along with Yelü Sha's son Yelü Deli (耶律德裏).
