Muhammad ibn Harun al-Rashid ibn al-Mahdi ibn al-Mansur — an Abbasid caliph, born in Rusafa, Baghdad. He was appointed caliph after the death of his father (in 193 AH) through a pledge of allegiance, and he appointed his brother Al-Ma'mun as governor of Khorasan and its outskirts. Al-Ma'mun was the heir apparent after him. In the year 195, Al-Amin declared the abdication of his brother Al-Ma'mun from the succession, and Al-Ma'mun called for the abdication of Al-Amin in Khorasan, and he took the title of Amir al-Mu'minin. Al-Amin sent his minister (Ibn Mahan) to fight him, and Al-Ma'mun sent Tahir ibn Husan. The two armies met, Ibn Mahan was killed, and Al-Amin’s army was defeated. Tahir ibn Husan pursued him and besieged Baghdad for a long time, ending with the killing of Al-Amin: he was killed with a sword in the city of Peace, and the one who struck his neck was a freed slave of Tahir, by his order. He was tall, white, and fat, beautiful in appearance, brave, literary, with fine hair, spendthrift, poor in management, and criticized for his distraction with entertainment and gatherings of friends.
