Algeria–Tunisia border

The border starts in the north at the Mediterranean coast, proceeding overland in a broadly southwards directions via a series of overland lines. In the southern sections of the border straight lines predominate, which eventually veer to the south-east down to the tripoint with Libya.[2]

France occupied much of the northern coastal areas of Algeria in the period 1830-47 and Tunisia in 1881, both of which had hitherto been subject to the nominal control of the Ottoman Empire.[3][2] France gradually pushed inland, annexing the Saharan areas of Algeria in 1902.[2] The border from the coast south to Bir Ramane was established by various French decrees, notably those of 1888-89 and 1901–01.[2] The sections south of this down to the Libyan tripoint was somewhat vaguer, and appear to have been delimited during the period 1911–23.[2]

Tunisia gained independence from France in 1956, followed by Algeria (following a bloody war) in 1962. The two states then confirmed the existing boundary between them by an agreement of 6 January 1960, with relations generally being positive.[2][4]
