Algeria–Mauritania border

[1] The border consists of a single straight line orientated NW-SE connecting the Western Saharan and Malian tripoints.

It runs through a remote, scarcely populated stretch of the Sahara desert.

This culminated in the Berlin Conference of 1884, in which the European nations concerned agreed upon their respective territorial claims and the rules of engagements going forward.

[2][3] As the movement for decolonisation grew in the post-Second World War era, France gradually granted more political rights and representation for their sub-Saharan African colonies, culminating in the granting of broad internal autonomy to French West Africa in 1958 within the framework of the French Community.

In 2018 the first ever border crossing between the two countries was proclaimed open, connecting Zouérat, Mauritania and Tindouf, Algeria, against a background of worsened insecurity in the Sahara region.
