The region is inhabited mainly by tribal Khasi dwellers, which are traditionally in various chieftainships, petty states known as the Khasi Hill States. One of its capitals, Cherrapunji, is considered one of the wettest places in the world.
The region came under the Khasi Hills district, which was divided into West Khasi Hills and East Khasi Hills districts on 28 October 1976.
