Burkina Faso–Niger border
Mostly straight lines drawn by a French colonial order in 1927. Its vague wording left a long middle stretch in dispute after independence, until the World Court fixed it in 2013 with straight lines, a river and an old map.

A line on paper
France created the colony of Upper Volta in 1919, and in 1927 moved the district of Say from it to Niger. A general order (arrêté) of 31 August 1927, corrected by an erratum of 5 October 1927, described the new boundary through a string of hills, fords, villages and astronomic markers.[1]
Upper Volta was abolished in 1932 and much of it given to Niger. Niger became independent on 3 August 1960. In 1964 officials of the two countries agreed at Niamey to use the 1927 texts and a 1:200,000 French map as the basis for marking the line, starting with the disputed Téra–Dori stretch. Upper Volta is now Burkina Faso.[1]
To the World Court
A further agreement at Ouagadougou on 28 March 1987 created a joint commission to mark the border. It settled the northern end, down to the Tong-Tong marker, and the southern end, from the Botou bend to the Mekrou, but not the stretch in between. By a Special Agreement signed at Niamey on 24 February 2009, the two countries asked the International Court of Justice to decide it.[2]
On 16 April 2013 the court ruled unanimously. From Tong-Tong to the Tao marker the border is a straight line. From Tao it follows the line on the 1960 French map to the Sirba river, then the middle of the Sirba, and then further lines, ending with a straight line to the Botou bend. The court also named three experts to help the two countries mark it on the ground.[2]
