The Gadaa system is an indigenous socio-political institution practiced by the Oromo people, primarily in Ethiopia. It's a complex system governing various aspects of life, including governance, social organization, and religious practices. Central to the Gadaa system is the concept of periodic power rotation, typically occurring every eight years, among age sets known as "Gadaa classes." Each class progresses through stages of responsibility from junior to senior roles, with specific duties and rights. Decision-making is consensus-based, emphasizing inclusivity and participation. The Gadaa system also encompasses cultural practices, rituals, and ceremonies, playing a vital role in maintaining social cohesion and identity within the Oromo community. Despite facing challenges and adaptations over time, the Gadaa system remains a significant aspect of Oromo culture, embodying principles of democracy, justice, and collective responsibility.
