The 2020-2023 cluster of military coups in the Sahel region: Mali (2020, 2021), Guinea (2021), Burkina Faso (2022), Niger (2023), Gabon (2023). Represents a potential structural break from the post-Cold War decline in coups. Characterized by anti-French/anti-Western framing, popular support, Wagner Group involvement, and weak international response. Tansey (2017) warned of 'anti-coup norm fading' before this wave materialized.
