The Coat of Arms of Ruanda-Urundi is a heraldic symbol that represents the former Belgian League of Nations mandate, encompassing present-day Rwanda and Burundi. It was officially adopted in 1923, following the signing of the Treaty of Versailles. The shield’s design features a golden lion passant guardant, symbolizing courage and vigilance, on a green field, which represents the fertile lands of the region. Above the shield, there is a crown made up of five crossed bananas and palm leaves, representing unity and agriculture, while beneath it, a scroll inscribed with the motto “Unity Makes Strength” (in Latin: “Unitas Fracturam Facit”) supports the shield. The Coat of Arms served as a symbol of the territorial entity until 1962 when Rwanda and Burundi gained their independence, leading to the adoption of separate national coats of arms for each country.
