African External Security Engagement Observatory (ASEO), 2000–2025

A country-year database of external military engagement with all 54 African states, 2000–2025: arms transfers (SIPRI TIV), foreign military bases, defence-cooperation agreements, UN/EU arms embargoes, and armed-conflict, governance and economic context. Compiled entirely from open sources; every record carries provenance and a confidence code, and no value is imputed. This record archives version 1.2 of the ASEO website — an interactive, bilingual (English/Turkish) presentation of the database, with continental maps, supplier and recipient profiles, the External Military Engagement Index (EMEI) and scenario outlooks. Live site: aseo-observatory.netlify.app Please also cite the underlying datasets (SIPRI, UCDP/PRIO, ACLED, Kinne DCAD, UN/EU, V-Dem, World Bank) where used.
