In the field of geography the Muslim scholars have made significant contributions in the fields of mathematical, physical, and regional geography. Their knowledge was based on the information gathered on the works of Greeks and other oriental civilizations. Through these observations and analytical reasoning they made noteworthy interpretations on different phenomenon occurring over the surface of the earth especially in the fields of climatology, geomorphology, cartography (determination of cardinal points) and so on.
Muslim geography flourished in the city of Baghdad and it became a centre of learning for more than a century.
Historical Background of Muslim Geographical Thought
Use of Scientific Methods:
Muslim geographers like Al-Maqadisi (945–1000 AD) adopted a systematic and scientific approach while documenting geographical knowledge.
They used three main sources of information:
Available written literature from past civilizations and scholars.
Firsthand observations from their own extensive travels.
Accounts from reliable individuals, especially about regions they couldn’t visit themselves.
Strong Culture of Travel and Exploration:
Travelling was not just a habit but a central part of their scholarly work. They believed that firsthand observation was the most authentic way to learn.
Examples of famous Muslim travelers:
Al-Idrisi (1100–1166 AD): Travelled widely across southern, northern, and western Europe; produced detailed maps.
Ibn Hauqal (943–969 AD): Visited regions in eastern Europe.
Al-Biruni (973–1050 AD): Travelled extensively in India, studied Indian culture and geography.
Ibn Battuta (1304–1368 AD): One of the most famous travelers of the medieval world; journeyed through India, China, and the entire Muslim world, including Timbuktu in Africa, located near the Niger River.
Comprehensive Nature of Their Work:
Unlike modern subject divisions, Muslim geographers wrote holistically, combining:
Other aspects like history, philosophy, religious beliefs, clothing, food habits, and social customs.
Most scholars were generalists, not specialists.
Exceptions:
Al-Dinawari (d. 805 AD): Specialized in climatology.
Al-Asma’i (d. 739 AD): Focused on plant geography.
Two Perspectives on Their Contributions:
Influence of Earlier Civilizations:
Their early geographical writings were deeply inspired by Persian, Indian, and Greek sources.
Independent Contributions:
They did not just copy old ideas but also corrected inaccuracies and added original insights based on their own studies and observations.
Development of New Subfields:
Muslim geographers were pioneers in diversifying the scope of geography.
They explored and wrote about:
Urban geography (structure and planning of cities)
Religious geography (distribution and influence of religious communities)
Linguistic geography (spread and pattern of languages)
Also made major contributions to astronomy and mathematical geography, improving map-making and understanding of Earth’s shape and size.
Prominent Arab Geographers and Their Contributions
During the Middle Ages, Muslim scholars made remarkable contributions to geography, both physical and human.
Their works were holistic, covering not only geography but also astronomy, history, philosophy, religion, culture, and society.
While Europe faced the Dark Ages, Muslim geographers advanced scientific thinking, preserving and expanding on Greek, Persian, and Indian knowledge.
Al-Balkhi
Created the first climatic atlas: Kitab-al-Ashkal (921 AD).
Used data from Arab travelers to map climate patterns globally.
Pioneered climatology in geography.
Al-Masudi
Scholar from Baghdad; geographer, historian, and explorer.
Important works: Mehraj-al-Duhab, Kitabul Aswat, Kitab Akhbar-Zaman.
Contributions:
Studied weather conditions and salt origin in seas.
Emphasized erosion and stream adjustment in shaping landforms.
Described spherical Earth.
Explored the relation between environment and culture (early environmental determinism).
Divided world into seven language-based regions.
Al-Biruni
Al-Biruni was a Tajik by race and a Persian by culture; his main interests include astronomy, mathematics, chronology, physics, medicine and history.
He was a prolific writer; books include Kitab-al-Hind, Al-Qanuan-Almasudi and Tarikul Hind.
Physical Geography:
Kitab-al-Hind (1030) is regarded as his monumental work which deals with the geography of India.
He describes the processes shaping the landforms under normal conditions and even identifies the significance of rounded stones in the alluvial deposits in the southern part of the Himalayas.
He mentioned that the distribution of rainfall in the peninsular region is controlled by the eastern and western Ghats.
He provided detailed information about the source of Indus and explained the phenomena of floods in its basin.
He gave the description of the city of Qannauj.
He has provided an accurate account of the seasons of India describing the nature of monsoons.
He had also studied Indian culture and Hindu beliefs.
Astronomy:
In his astronomical writings he discussed and approved the earth’s theory of rotation on its axis and correctly calculated the latitudes and longitudes of many places.
He provided his views on the origin of universe in his book Al-Tahidi.
He explained the phenomena of solar and lunar eclipses.
He also attempt to measure the longest and the shortest distance of the moon and the sun from the earth.
He studied the relationship of tides with the phases of moon.
Geomorphology:
In geomorphology he compared the fossils discovered in the plans of Arabia, Jurjan and Khwarizmi along the Caspian Sea and suggested the occurrence of sea at these places in the earlier times.
One of the most interesting observations made by him is that “at the south pole the night ceases to exist”.
Ibn Sina
Made significant contribution to geomorphology.
He gave the idea of landscape erosion when he observed that the streams cut down their valleys when flowing down the mountains. He further states that these streams worn down the mountains in a slow but steady process.
He even examined the presence of fossils in the rocks in higher mountains.
Al-Idrisi
Al idrisi was a leading scholar of the 12th century. His most important and famous book was Amusements for Him Who Desire to Travel Around the World (1154).
His world map is considered as his most important contribution to geography. His map was based on a rough rectangular projection.
He had studied Ptolemy’s work. His description of Sicily is perhaps the most detailed one and it is of great historical importance.
Al Idrisi travelled over a great part of world including Spain, France, England, Sicily, Morocco, Asia Minor and interior parts of Africa.
He described the course of many rivers including the Danube and Niger with precision.
He did not agree with the Greek’s classification of the world into five climatic divisions and provided a more sophisticated classification based on climate.
Ibn Batuta
Ibn Batuta was the greatest Muslim traveler of his time. He spent 28 years in travel and crossed a distance of more than 75000 miles.
His primary interest was in people though he has described the physical conditions of various regions that he visited. His description of house types and building materials in deserts is very interesting and informative. Through his experience he labels Morocco as the best of the countries.
His book Rihlah provides an insight into the soils, agriculture, economy and political history of the then Muslim world.
He came to Delhi on an invitation of Mohd. Tughlak and served as a Qazi of Delhi.
Ibn Khaldun
Ibn Khaldun was basically a historian but his writings also have been important as they were based on travel. His most important work is known as Muqaddimah.
In his writings, Ibn Khaldun has maintained that the northern hemisphere is more densely populated than the southern. He stated that the population along the equator is sparse, but there is an increasing concentration away from it up to 60 degrees. Further away there is little or no population.
He emphasized the role of fertile land in the origin of settlements. He has argued that the origin of the large cities have always been in the form of small settlements.
Ibn Khaldun is considered as one of the early environmental determinists as he tried to correlate man and his environment in a scientific way.
He is also credited of establishing political geography in the middle period where he discusses the rise and fall of dynasties and empires. He formulated the first concept of life-cycle of the state.
In the words of Kimble (1938) “Khaldun may be considered to have discovered the true scope and nature of geographical enquiry but the fact remains that his knowledge of the physical earth is based largely on Greek theory; and his ideas about environment influence are not highly sophisticated.”
