Jammu and Kashmir -

Divided between India, Pakistan, and China, the territory of Jammu and Kashmir has been disputed since the British renounced control of the region in 1947.

Somaliland -

The current boarders of Africa are the result of the competition between colonial powers, such as Britain and France, for the control of the continent. During World War II, all the Somali territories were unified under British military administration, except French Somaliland. This continued until Somalia became independent in 1960.

Somaliland -

However, during the civil war, the northern region of Somaliland declared its independence in 1991. The territory has remained unrecognized by Somalia and the international community.
