A writer and historian, he is famous for authoring his two famous books: “The Civilization of Islam in Dar al-Salaam” and “The History of Babylon and Assyria.” The critic and writer Ibrahim al-Yaziji corrected what he wrote. Jamil Nakhleh al-Mudawwar was born in Beirut in 1862 AD into a family known for its virtues and the literature of its owners. He lived most of his life in Egypt, and was fond of excavating in Arab literature and the history of ancient eastern nations, so he classified in his modernity “The History of Babylon and Assyria.” He was well acquainted with the French language; He translated the book of ancient history and the story "Atla" by the French writer "Chateaubriand" in 1882 AD, when he was about twenty years old. With Mudawar's knowledge of French literature, he was impressed by the book "The Journey of the Young Man, Ana Chersis"; It is a journey imagined by its writer, the monk Barthelemy, undertaken by the so-called “I Charsis” in Greece a few years before the death of Alexander the Great. This traveler conveyed his notes on all the destinations he visited; From the habits of its people, their social life, and the nature of their government. The author gave him an introduction that includes all that can be known about Greece, from traditions, arts and wars, from ancient times to the era of Philip the Macedonian, father of Alexander the Great. This book took thirty years of research and writing, and appeared in the same year that the French Revolution broke out. The French novel made a profound impact on Al Mudawar because of its refined style and amusing subject matter. Which made him quote the same idea from her, and use it skillfully to reveal to us a flourishing era of Islamic history, following the method of the mentioned French writer. And if “Barthelemy” had chosen for his book the era of Alexander the Great, then Al-Mudawwar also chose a bright era from the eras of Islam, the era of Caliph Harun al-Rashid; Where Baghdad (Dar al-Salaam) was the capital of the Caliphate and the beacon of civilization. Jamil Nakhleh al-Mudawwar died in Cairo in January 1907.
