The term 'Native Ruler of Africa' can be summarized as an EMIR, which is a 4-letter word. An EMIR is a Muslim ruler or leader in the Middle East and North Africa, typically one with political or military authority. Historically, Emirs have been rulers of independent states, or of vassal states under larger empires. In modern times, the title is often used to describe a powerful local or regional leader. In Africa, Emirs are often found in countries with a strong Islamic presence, such as Morocco, Algeria, and Tunisia.
