History
The village of Kao Kham was founded in the early 20th century in an abandoned village area. The name "Kao Kham" is made up of two parts: Kao เก่า means "old", which refers to the abandoned settlement where the village is located, and Kham ขาม refers to "Ma Kham" (tamarind), a leguminous tree bearing edible fruit that was found numerously in the area before the village was settled. At its early age, the village was administrated from Yang, but it was later promoted to tambon (subdistrict) in 1993 by absorbing seven other villages in Yang's southern territory.

After independence, Tambon Yang Yai was governed by the Subdistrict Council of Yang until the council was later upgraded to the Subdistrict Administrative Organization (SAO) in 1996.

Geography
