Ibn Khaldūn or Ibn Khaldoun (full name, Arabic: أبو زيد عبد الرحمن بن محمد بن خلدون الحضرمي, Abū Zayd ‘Abdu r-Raḥman bin Muḥammad bin Khaldūn Al-Hadrami, May 27, 1332 AD/732 AH – March 19, 1406 AD/808 AH) was an Amazigh polymath] — an astronomer, economist, historian, Islamic jurist, Islamic lawyer, Islamic scholar, Islamic theologian, hafiz, mathematician, military strategist, nutritionist, philosopher, social scientist and statesman—born in North Africa in present-day Tunisia. He is considered a forerunner of several social scientific disciplines: demography, cultural history, historiography, the philosophy of history, and sociology.He is also considered one of the forerunners of modern economics, alongside the earlier Indian scholar Chanakya.
Ibn Khaldun is considered by many to be the father of a number of these disciplines, and of social sciences in general, for anticipating many elements of these disciplines centuries before they were founded in the West. He is best known for his Muqaddimah (known as Prolegomenon in English), the first volume of his book on universal history, Kitab al-Ibar. However, Ibn Khaldun's ideas were not absorbed by his society, nor were they carried forward by its future generations. Muslims had ignored and lost him for centuries until he was rediscovered by the West in the 19th century as one of the greatest philosophers of Islam.
Background and Family
He was born in Tunis in AD 1332 (732 A.H.) into an upper-class Andalusian family, the Banū Khaldūn. His family, which held many high offices in Andalusia, had emigrated to Tunisia after the fall of Seville to Reconquista forces around the middle of the 13th century. Under the Tunisian Hafsid dynasty some of his family held political office; Ibn Khaldūn's father and grandfather however withdrew from political life and joined a mystical order. His brother, Yahya Ibn Khaldun, was also a historian who wrote a book on the Abdalwadid dynasty, and who was assassinated by a rival for being the official historiographer of the court.
At the age of 17, Ibn Khaldūn lost both his parents to the Black Death, an intercontinental epidemic of the plague that hit Tunis in 1348–1349.
