Türkiye has earned a particular place among middle powers who exercise an extra-regional foreign policy in Africa, going beyond its geopolitical area. The scholarship has described Türkiye as an established middle power, exposing its grand strategy in the Middle East to evidence how the country has embraced its ‘peacekeeper’ role in security policies especially with two countries: Somalia and Libya. However, a few studies have analysed Ankara’s behaviour by looking at the security dimension in the form of a shelter-offer as a middle power. Moreover, fewer studies have considered how Ankara’s aid towards small states in Africa has altered the systemic environment. By examining how Türkiye has intertwined bilateral relations with Somalia and Libya, it is possible to observe a new pattern of how a middle power can adapt its peacekeeping and mediating behaviour to expand its influence in the North and Horn of Africa. The analysis adopts a method of inquiry based on the behavioural and systemic-impact model, investigating the consequences of the Turkish security policies in Libya and Somalia and examining the behavioural patterns of Türkiye’s middlepowerness as a security- builder. The paper concludes that Türkiye’s shelter offer diverges in the two case studies, manifesting a more aggressive form of shelter in Libya, while maintaining a more balanced approach in Somalia.
