The Alliance of Sahel States (AES), created in September 2023 by the three military governments of Mali, Niger and Burkina Faso as a counterweight to ECOWAS and the postcolonial influence of France and other Western countries, announced the creation of a confederation of its three countries in July 2024. The AES have more in common than the other countries of the Sahel. First, they are the centre of the Sahel and most vulnerable to jihadism. They figure among the least developed countries, with 40% to 50% of the population living in poverty. They are also landlocked countries with vast desert areas, making them more vulnerable to climate change. Finally, they are the countries with the highest population growth in the Sahel, with an average of six children per woman. The creation of the AES came amid a decade of escalating unrest in the Sahel, fuelled by the aftermath of the NATO-led intervention in Libya in 2011. The resulting instability caused rampant arms trafficking and the rise of armed groups linked to al-Qaeda and the Islamic State. The Sahel region accounts for a staggering 43% of global terrorist deaths, more than South Asia, the Middle East and North Africa combined. AES counterinsurgency operations will focus on the Liptako-Gourma region, the vast and porous border area where the three states meet, a borderland notorious for its instability. Previous leaders have often put French interests ahead of those of their own people, allowing the continued exploitation of the region's natural resources, including uranium, gold and manganese, without much benefit to the local population. In the face of critical comments from the AU about the AES countries' exit from ECOWAS, the former rejected any interference in their internal affairs. The AES confederation will expand the operational space of the junta alliance and consolidate its military and economic partnership with Russia and China, as well as Turkey and Iran. However, the AES secession undermines the legitimacy of ECOWAS by hindering regional economic and security integration and further complicating the return to democratization. The confederation will seek to absorb new members such as Chad, Guinea and Sudan to further strengthen its power and legitimacy as an alternative regional bloc. However, a divided Sahel will make tackling regional challenges even more difficult. If the AES were to replace the CFA franc with its own currency, as announced, and other Francophone countries in the UEMOA were to follow suit, this would require a fundamental restructuring of both the UEMOA and ECOWAS and finally also call into question the introduction of the ECO, the common West African currency, envisaged for 2027.
