From the seventh century onwards, the rise of Islam was critical in uniting the warring Arab tribes into a powerful empire. Apart from Arabia, the early caliphs established an Arab empire that included Syria, Iraq, Iran, Egypt, North Africa, and Spain. In this article, we will discuss the Arab World During Medieval Times which will be helpful for UPSC exam preparation.

Arab World - Background

• Following internal conflicts and civil war among Arab tribes, the caliph of Damascus was deposed in the middle of the eighth century, and a new dynasty known as the Abbasids took power.
• They established their capital in Baghdad, a newly founded city. The Abbasids claimed to be descended from the same tribe as the Prophet Muhammad and were thus considered holy.
• For about 150 years, the Abbasid empire was one of the world's most powerful and flourishing empires. At its peak, it encompassed all of the region's major civilizations, including parts of North Africa, Egypt, Syria, Iran, and Iraq.
• The Abbasids ruled not only some of the most important regions of West Asia and North Africa, but also the vital trade routes that connected the Mediterranean world to India.
• The safety and security provided by the Abbasids to these trade routes was an important factor in the area's wealth and prosperity, as well as the splendour and magnificence of the Abbasid court.
• The Arabs were astute merchants who quickly rose to prominence as the most enterprising and wealthy merchants and seafarers in the world at the time. Numerous cities arose, each with magnificent private and public buildings.
• The standard of living and cultural environment in Arab towns could hardly be matched in any other country in the world at the time.
• The Arabs also established the gold dinar and the silver dirham, which became the world's currency. The Arabs' access to African gold made this possible.
• The Arabs also pioneered double entry bookkeeping, advanced accounting, and large-scale and elaborate banking and credit, including bills of exchange (hundis).

Caliphs of this Period

• Al-Mamun and Harun al-Rashid were the most famous caliphs of this period. The splendour of their court and palaces, as well as their patronage of men of science and learning, inspired numerous stories and legends.
• During the early period, the Arabs demonstrated an extraordinary ability to absorb the scientific knowledge and administrative skills of the ancient civilizations they had conquered.
• They had no qualms about hiring non-Muslims, such as Christians and Jews, as well as non-Arabs, particularly Iranians, many of whom were Zoroastrians or even Buddhists, to manage the administration.
• Although the Abbasid caliphs were orthodox Muslims, they welcomed learning from all sources as long as it did not challenge Islam's fundamental tenets.
• The Caliph Al-Mamun established a 'House of Wisdom' (bait-ul-hikmat) in Baghdad to translate knowledge from various civilizations—Greek, Byzantine, Egyptian, Iranian, and Indian—into Arabic.
• Individual nobles followed the example set by the Caliphs. Almost all of the important scientific works from various countries had become available in Arabic in a short period of time.
• We know a lot about the impact of Greek science and philosophy on the Arabs, thanks to the work of a dedicated group of European scholars in recent years.

Arab World - Growth

• By the beginning of the tenth century, the Arabs had advanced to the point where they could contribute to various sciences on their own.
• The growth of geometry, algebra, geography, astronomy, optics, chemistry, medicine, and other sciences in the Arab world during this period propelled it to the forefront of science.
• Arab geographers' writings and maps advanced knowledge of the world. The Arabs also contributed to the development of new devices for crossing the open sea.
• These devices were still in use until the fifteenth century. The accounts of Arab traders about India and its neighbours during this time period are a valuable source of information for us.

Arab Science

• What distinguished this new Arab-centered civilization was its willingness to examine and comprehend Greek classical scientific and philosophical traditions in the context of its own vibrant culture.
• This was made possible by written documents that reached the Arabs as the Roman Empire spread. They also had a strong sense of being the heirs of the ancients.
• They traced the store of knowledge back to the original Greek works, one step at a time. They translated these writings, absorbed them, and expanded on them.
• Caliph Al-Mamun established the Dar el Hikhma translation bureau, where the great scholars Hunain ibn Ishaac and Thabit ibn Khurra prepared Arabic texts of most of Aristotle's and Ptolemy's writings, as well as other major Greek scientific classics.
• The great Caliphs, Al-Mansur, Haroun-al-Raschid, Al-Mamun, and Al-Mutawahkil, supported these scholars.
• They also translated Indian texts on medicine, surgery, and astronomy.
• This was aided by the extensive travels of merchants, travellers, and scholars like Al-Biruni (973-1048 A.D.), who brought back knowledge of local practises from distant lands like India, Greece, and China.

Arab Science - Growth

• Arab science began to decline after the twelfth century, partly as a result of political and economic developments in the region, but more importantly as a result of growing orthodoxy, which stifled free thought. However, it grew in Spain until the fourteenth century.
• This created strong links between ordinary craftsmen and scholars, which never fail to provide a significant impetus to the advancement of science.
• The remarkable degree of intellectual and personal freedom enjoyed by scientists and scholars, as well as the patronage extended to them, contributed significantly to the remarkable growth of Arab science and civilization.
• Due to the church's rigid attitude at the time, such freedom was not available in Europe.
• Perhaps conditions in India were similar, because few Arab sciences were able to enter India, and the growth of Indian science slowed during the period.

Contribution to Various Sciences

Astronomy and Mathematics

• In astronomy, Arabs continued the Greek tradition. Despite religious interference, they translated Ptolemy's Almagest and continued astronomical observations.
• Although they did not significantly improve on Greek methods, the continuity they provided was invaluable to sixteenth-century astronomers.
• Astronomy provided the necessary impetus for the development of mathematics.
• In this regard, the Arabs adopted the Indian system of numbers and widely adopted it, to the point where warehouse clerks and traders began using these numerals to conduct business.
• The widespread use of the number system facilitated calculations and had the same impact on mathematics as alphabets did on writing.
• Arabs translated Indian algebra and trigonometry works and used them to solve a variety of physical and practical problems.

Medicines

• The Arabs continued the Greek tradition in medicine as well, but added knowledge of new diseases and drugs made possible by Islam's wide geographical spread.
• The doctors, who were both Muslim and Jewish, researched a wide range of diseases.
• They were interested in the effects of climate, hygiene, and diet on health.
• They also focused on the practical art of cooking.

Optics

• The prevalence of eye diseases in desert and tropical countries prompted Arab doctors to conduct eye research.
• The surgical treatment of the eye sparked renewed interest in the structure of the eye.
• This was to provide Arab physicians with their first real understanding of dioptrics, the branch of optics concerned with the passage of light through transparent bodies such as lenses or glass.
• This also laid the groundwork for modern optics. The lens of the eye was to point the way to the use of crystal or glass lenses for magnification and reading, particularly by the elderly.
• The 'Optical Thesaurus' of Ibn al-Haitham (about 1038 A.D.) was the first serious scientific treatment of the subject.

Scientific Chemistry

• In chemistry, Arab doctors, perfumers, and metallurgists made the most significant contributions.
• This was primarily due to the fact that, unlike their Greek counterparts, Arab scholars never hesitated to participate in laboratory practises involving drugs, salts, and precious metals.
• The Arabs carried on the Egyptian and Babylonian traditions, as well as learning from Indian and Chinese sources.
• They added their own rich contributions, giving rise to the first scientific chemistry statements.
• The earlier distillation apparatus was greatly improved by Arab chemists and used for large-scale perfume production.
• They also began large-scale production of soda, alum, copperas (iron sulphate), nitre, and other salts, all of which were exported and used primarily in the textile industry.
• They were not satisfied with new techniques until they could get to the bottom of the reactions that made these techniques possible.
• The positive and negative nature of two reacting constituents were specified by Arab chemists.
• This was the first time chemical transformation was approached logically, laying the groundwork for modern chemistry.

Geography

• Arabs have proven to be excellent travellers. Scholars from the Arab world have travelled to Russia, Central Africa, India, and China.
• They made maps and charts and wrote well-organized and logical accounts of their journeys.
• Their geography was not only descriptive, but they also had an idea of scale and size.
• They laid the groundwork for modern Asian and Northern African geography in this way.

Conclusion

Unfortunately, we know very little about India's economic and cultural relations with the Arab world during this time period, as well as India's scientific contribution to it. Sind did become a conduit of scientific and cultural links between India and the Arab world after its conquest by the Arabs in the eighth century. During this time, the decimal system, which is the foundation of modern mathematics and was developed in India in the fifth century, made its way to the Arab world.
