Abstract
Language is a critical tool in diplomacy, facilitating communication, negotiation, and international cooperation. Hausa, one of Africa's most widely spoken indigenous languages, plays a significant role in diplomatic engagements, particularly in West and Central Africa. Thus, this paper explores Hausa’s historical and contemporary relevance in diplomatic interactions, including regional trade, peace negotiations, and international relations. The study highlights how the language serves as a unifying medium across borders and its potential for enhancing African diplomatic efforts.
