The Majeerteen Sultanate (Somali: Suldanadda Majeerteen, Arabic: سلطنة مجرتين‎‎), also known as Majeerteenia and Migiurtinia, was a Somali Sultanate centered in the Horn of Africa. Ruled by Boqor Osman Mahamuud during its golden age, it controlled much of northern and central Somalia in the 19th and early 20th centuries. The polity had all of the organs of an integrated modern state and maintained a robust trading network. It also entered into treaties with foreign powers and exerted strong centralized authority on the domestic front. Much of the Sultanate's former domain is today coextensive with the autonomous Puntland region in northeastern Somalia.
