ECOMOG stands for ECOWAS Monitoring Group. It was a multinational military force established by the Economic Community of West African States (ECOWAS) to intervene in conflicts in West Africa during the 1990s. The primary objective of ECOMOG was to promote peace and stability in the region by monitoring and enforcing ceasefires, disarming combatants, and protecting civilians. ECOMOG played a critical role in resolving several conflicts in the region, including the Liberian civil war and the Sierra Leone civil war.
