Negus (Ge'ez: ንጉሥ, nəgūś IPA: [nɨguːɬ]; Amharic: nigūs; cf. Tigrinya: ነጋሲ negus) is a royal title in the Ethiopian Semitic languages.[1] It denotes a monarch,[2] such as the Bahri Negasi (King of the Sea) of the Medri Bahri kingdom in pre-1890 Eritrea, and the Negus in pre-1974 Ethiopia. The Negus is referred to as An-Najashi (النجاشي) in the Islamic tradition.
