The Radhanites (also Radanites, Arabic الرذنية ar-Raðaniyya; Hebrew sing. רדהני Radhani, pl. רדהנים Radhanim) were medieval Jewish merchants. Only a limited number of primary sources use the term, and it remains unclear whether they referred to a specific guild, or to a clan, or generically to Jewish merchants in the trans-Eurasian trade network. Jewish merchants operated in trade between the Christian and Islamic worlds during the early Middle Ages (approximately 500–1000). Many trade routes previously established under the Roman Empire continued to function during that period – largely through their efforts. Their trade network covered much of Europe, North Africa, the Middle East, Central Asia and parts of India and China.
Several etymologies have been suggested for the word “Radhanite”. Many scholars, including Barbier de Meynard and Moshe Gil, believe it refers to a district in Mesopotamia called “the land of Radhan” in Arabic and Hebrew texts of the period. Others maintain that their center was the city of Ray (Rhages) in northern Persia. Cecil Roth and Claude Cahen, among others, make the same claim about the Rhône River valley in France, which is Rhodanus in Latin. The latter claim that the center of Radhanite activity was probably in France as all of their trade routes began there. Still others maintain that the name derives from the Persian terms rah “way, path” and dān “one who knows”, meaning “one who knows the way”. English-language (or Western) sources added the suffix -ite to the term, as is done with ethnonyms or names derived from place names.
The activities of the Radhanites are documented by ibn Khordadbeh – the postmaster, chief of police (and spymaster) for the province of Jibal, under the Abbasid Caliph al-Mu’tamid – when he wrote Kitab al-Masalik wal-Mamalik (Book of Roads and Kingdoms), in about 870. Ibn Khordadbeh described the Radhanites as sophisticated and multilingual. He outlined four main trade routes utilized by the Radhanites in their journeys; all four began in the Rhone Valley in southern France and terminated on the east coast of China. Radhanites primarily carried commodities that combined small bulk and high demand, including spices, perfumes, jewellery, and silk. They are also described as transporting oils, incense, steel weapons, furs, and slaves.
- These merchants speak Arabic, Persian, Roman, the Frank, Spanish, and Slav languages. They journey from West to East, from East to West, partly on land, partly by sea. They transport from the West eunuchs, female slaves, boys, brocade, castor, marten and other furs, and swords. They take ship from Firanja (France), on the Western Sea, and make for Farama (Pelusium). There they load their goods on camel-back and go by land to al-Kolzum (Suez), a distance of twenty-five farsakhs. They embark in the East Sea and sail from al-Kolzum to al-Jar and al-Jeddah, then they go to Sind, India, and China. On their return from China they carry back musk, aloes, camphor, cinnamon, and other products of the Eastern countries to al-Kolzum and bring them back to Farama, where they again embark on the Western Sea. Some make sail for Constantinople to sell their goods to the Romans; others go to the palace of the King of the Franks to place their goods. Sometimes these Jew merchants, when embarking from the land of the Franks, on the Western Sea, make for Antioch (at the head of the Orontes River); thence by land to al-Jabia (al-Hanaya on the bank of the Euphrates), where they arrive after three days’ march. There they embark on the Euphrates and reach Baghdad, whence they sail down the Tigris, to al-Obolla. From al-Obolla they sail for Oman, Sindh, Hind, and China.
- These different journeys can also be made by land. The merchants that start from Spain or France go to Sus al-Aksa (in Morocco) and then to Tangier, whence they walk to Kairouan and the capital of Egypt. Thence they go to ar-Ramla, visit Damascus, al-Kufa, Baghdad, and al-Basra, cross Ahvaz, Fars, Kerman, Sind, Hind, and arrive in China.
- Sometimes, also, they take the route behind Rome and, passing through the country of the Slavs, arrive at Khamlidj, the capital of the Khazars. They embark on the Jorjan Sea, arrive at Balkh, betake themselves from there across the Oxus, and continue their journey toward Yurt, Toghuzghuz, and from there to China.
During the Early Middle Ages the Islamic polities of the Middle East and North Africa and the Christian kingdoms of Europe often banned each other’s merchants from entering their ports. Corsairs of both sides raided the shipping of their adversaries at will. The Radhanites functioned as neutral go-betweens, keeping open the lines of communication and trade between the lands of the old Roman Empire and the Far East. As a result of the revenue they brought, Jewish merchants enjoyed significant privileges under the early Carolingians in France and throughout the Muslim world, a fact that sometimes vexed local Church authorities.
While most trade between Europe and East Asia had historically been conducted via Persian and Central Asian intermediaries, the Radhanites were among the first to establish a trade network that stretched from Western Europe to Eastern Asia. More remarkable still, they engaged in this trade regularly and over an extended period of time, centuries before Marco Polo and ibn Battuta brought their tales of travel in the Orient to the Christians and the Muslims, respectively. Indeed, ibn Battuta is believed to have traveled with the Muslim traders who traveled to the Orient on routes similar to those used by the Radhanites.
While traditionally many historians believed that the art of Chinese paper-making had been transmitted to Europe via Arab merchants who got the secret from prisoners of war taken at the Battle of Talas, some believe that Jewish merchants such as the Radhanites were instrumental in bringing paper-making west. Joseph of Spain, possibly a Radhanite, is credited by some sources with introducing the so-called Hindu-Arabic numerals from India to Europe. Historically, Jewish communities used letters of credit to transport large quantities of money without the risk of theft from at least classical times. This system was developed and put into force on an unprecedented scale by medieval Jewish merchants such as the Radhanites; if so, they may be counted among the precursors to the banks that arose during the late Middle Ages and early modern period.
Some scholars believe that the Radhanites may have played a role in the conversion of the Khazars to Judaism. In addition, they may have helped establish Jewish communities at various points along their trade routes, and were probably involved in the early Jewish settlement of Eastern Europe, Central Asia, China and India.
Besides ibn Khordadbeh, the Radhanites are mentioned by name only by a handful of sources. Ibn al-Faqih’s early 10th century Kitab al-Buldan (“Book of the Countries”) mentions them, but much of ibn al-Faqih’s information was derived from ibn Khordadbeh’s work. Sefer ha-Dinim, a Hebrew account of the travels of Yehuda ben Meir of Mainz, named Przemyśl and Kiev as trading sites along the Radhanite route. In the early 12th century, a French-Jewish trader named Yitzhak Dorbelo wrote that he traveled with Radhanite merchants to Poland.
The fall of the Tang Dynasty of China in 908 and the destruction of the Khazar Khaganate some sixty years later (circa 968–969 AD) led to widespread chaos in Inner Eurasia, the Caucasus and China. Trade routes became unstable and unsafe, a situation exacerbated by Turkic invasions of Persia and the Middle East, and the Silk Road largely collapsed for centuries. This period saw the rise of the mercantile Italian city-states, especially Genoa, Venice, Pisa, and Amalfi, who viewed the Radhanites as unwanted competitors.
The economy of Europe was profoundly affected by the disappearance of the Radhanites. For example, documentary evidence indicates that many spices in regular use during the early Middle Ages completely disappeared from European tables in the 10th century. Jews had previously, in large parts of Western Europe, enjoyed a virtual monopoly on the spice trade.
Some have speculated that a collection of 11th century Jewish scrolls discovered in a cave in Afghanistan’s Samangan province in 2011 may be a “leftover” of the Rhadanites, who had mostly disappeared by the 11th century.
