Ibrahim of the Ottoman Empire

Ibrahim (/ˌɪbrəˈhiːm/; Ottoman Turkish: ابراهيم; Turkish: İbrahim; 5 November 1615 – 18 August 1648) was the Sultan of the Ottoman Empire from 1640 until 1648. He was born in İstanbul, the son of Ahmed I by Valide Kösem Sultan, an ethnic Greek originally named Anastasia. He was called “Deli Ibrahim” (“Ibrahim the Mad”) due to his mental condition and behavior. However Scott Rank notes that his opponents spread rumors of the sultan’s insanity, and some historians suggest he was more incompetent than mad.
