The Rise of Islamic Geography in the Middle Ages

After the fall of the Roman Empire in the fifth century CE, the average European's knowledge of the world around them was limited to their local area and to maps provided by the religious authorities. The European global explorations of the fifteenth and sixteenth century would not likely have come as soon as they did, were it not for the important work of the translators and geographers of the Islamic world.

The Islamic empire began to expand beyond the Arabian Peninsula after the death of the prophet and founder of Islam, Mohammed, in 632 CE. Islamic leaders conquered Iran in 641 and in 642, Egypt was under Islamic control. In the eighth century, all of northern Africa, the Iberian Peninsula (Spain and Portugal), India, and Indonesia became Islamic lands. The Muslims were stopped from further expansion into Europe by their defeat at the Battle of Tours in France in 732. Nonetheless, Islamic rule continued on the Iberian Peninsula for nearly nine centuries.

Around 762, Baghdad became the intellectual capital of the empire and issued a request for books from throughout the world. Traders were given the weight of the book in gold. Over time, Baghdad accumulated a wealth of knowledge and many key geographical works from the Greeks and Romans. Two of the first books translated were Ptolemy's "Almagest," which was a reference to the location and movement of heavenly bodies and his "Geography," a description of the world and a gazetteer of places. These translations kept the information held in these books from disappearing. With their extensive libraries, the Islamic view of the world between 800 and 1400 was much more accurate than the Christian view of the world.

Role of Exploration in Islam

The Muslims were natural explorers because the Koran (the first book written in Arabic) mandated a pilgrimage (hajj) to Mecca for every able-bodied male at least once in their lifetime. Dozens of travel guides were written to assist the thousands of pilgrims traveling from the farthest reaches of the Islamic Empire to Mecca. By the eleventh century, Islamic traders had explored the eastern coast of Africa to 20 degrees south of the Equator (near contemporary Mozambique).

Islamic geography was primarily a continuation of Greek and Roman scholarship, which had been lost in Christian Europe. Islamic geographers, especially Al-Idrisi, Ibn-Batuta, and Ibn-Khaldun, made some new additions to the accumulated ancient geographic knowledge.

Three Prominent Islamic Geographers

Al-Idrisi (also transliterated as Edrisi, 1099–1166 or 1180) served King Roger II of Sicily. He worked for the king in Palermo and wrote a geography of the world called "Amusement for Him Who Desires to Travel Around the World," which wasn't translated into Latin until 1619. He determined the circumference of the earth to be about 23,000 miles (it is actually 24,901.55 miles).

Ibn-Batuta (1304–1369 or 1377) is known as the "Muslim Marco Polo." In 1325 he traveled to Mecca for a pilgrimage and, while there, he decided to devote his life to travel. Among other places, he visited Africa, Russia, India, and China. He served the Chinese emperor, the Mongol emperor, and the Islamic sultan in a variety of diplomatic positions. During his life, he traveled approximately 75,000 miles, which at the time was farther than anyone else in the world had traveled. He dictated a book that was an encyclopedia of Islamic practices around the world.

Ibn-Khaldun (1332–1406) wrote a comprehensive world history and geography. He discussed the effects of the environment on humans, and he is known as one of the first environmental determinists. He believed that the northern and southern extremes of the earth were the least civilized.

Historical Role of Islamic Scholarship

Islamic explorers and scholars contributed new geographic knowledge of the world and translated important Greek and Roman texts, thereby preserving them. In so doing, they helped lay the necessary groundwork that allowed for the European discovery and exploration of the Western hemisphere in the fifteenth and sixteenth centuries.
