Murad IV

Murad IV was the sultan of the Ottoman Empire from 1623 to 1640, known both for restoring the authority of the state and for the brutality of his methods. Murad IV was born in Constantinople, the son of Sultan Ahmed I and Kösem Sultan. He was brought to power by a palace conspiracy when he was just 11 years old, and he succeeded his uncle, Mustafa I. Until he assumed absolute power on 18 May 1632, the empire was ruled by his mother, Kösem Sultan, as nāʾib-i salṭanat (regent). His reign is most notable for the Ottoman–Safavid War, of which the outcome would partition the Caucasus between the two Imperial powers for around two centuries, while it roughly laid the foundation for the current Turkey–Iran–Iraq borders.²
