It is mean: courage Abu Mansur Makan ibn Kaki (died 25 December 940) was a Daylamite military leader active in northern Iran (esp. Tabaristan and western Khurasan) in the early 10th century. He became involved in the succession disputes of the Alids of Tabaristan, and managed to establish himself as the ruler of Tabaristan and Gurgan for short periods of time, in competition to other Daylamite warlords such as Asfar ibn Shiruya or the Ziyarid brothers Mardavij and Vushmgir. He alternately opposed and secured support from the Samanid governors of Khurasan, and eventually fell in battle against a Samanid army.
