Mirzā Jahāngir Khān (≈1870, or 1875, Shiraz — June 23, 1908, Tehran) (Persian: میرزا جهانگیرخان), also known as Mirzā Jahāngir Khān Shirāzi (شيرازى ) and Jahāngir-Khān-e Sūr-e-Esrāfil (جهانگیرخان صوراسرافیل), was an Iranian writer and intellectual, and a revolutionary during the Iranian Constitutional Revolution (1905–1911). He is best known for his bold editorship of the progressive weekly newspaper Sur-e Esrāfil, of which he was also the founder. He was executed, at the age of 38, or 32, for his revolutionary zeal, following the successful coup d'état of Mohammad-Ali Shah Qajar in June 1908. His execution took place in Bāgh-e Shāh (باغشاه - The Garden of Shah) in Tehran, and was attended by Mohammad-Ali Shah himself. He shared this fate simultaneously with his fellow revolutionary Mirzā Nasro'llah Beheshti, better known as Malek al-Motakallemin. It has been reported that immediately before his execution he had said "Long live the constitutional government" (Zendeh bād Mashrouteh) and pointed to the ground and uttered the words "O Land, we are [being] killed for the sake of your preservation [/protection]" (Ey Khāk, mā barāye hefz-e to koshteh shodim).
Mirzā Jahāngir Khān was born to a relatively impoverished family from Shiraz. In his youth he studied Persian literature, logic, philosophy and mathematics with the masters of these subjects in his birthplace Shiraz. He later moved to the capital city Tehran where he embarked on studying modern sciences at the élite school of Dar ol-Fonoon and some other centres of learning available in this city at his time. At the inception of the movement leading to the Constitutional Revolution, he joined a number of underground groups of revolutionaries and before long became one of the main pillars of the Revolution. He became a devotee of Hāj Sheikh Hādi Najmābādi. Although it is known that Mirzā Jahāngir Khān was an Azali Bábí, we do not know whether he became a Bábí in Shiraz, the cradle of Bábism, or in Tehran.
