The Radhanites or Radanites (; ) were early medieval Jewish merchants, active in the trade between Christendom and the Muslim world during roughly the 8th to the 10th centuries. 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.

Only a limited number of primary sources use the term, and it remains unclear whether they referred to a specific guild, to a clan, or generically to Jewish merchants in the trans-Eurasian trade network.

Radhanite

Name

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.

Radhanite

Another hypothesis suggests that the name might be derived from the city of Ray (Rhages) in northern Iran. Still others think the name possibly derives from the Persian terms rah "way, path" and dān "one who knows", meaning "one who knows the way".

Radhanite

Two western Jewish historians, Cecil Roth and Claude Cahen, have suggested a connection to the name of the Rhône River valley in France, which is Rhodanus in Latin and Rhodanos (Ῥοδανός) in Greek. They claim that the center of Radhanite activity was probably in France as all of their trade routes began there.

English-language and other Western sources added the suffix -ite to the term, as is done with ethnonyms or names derived from place names.

Activities

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 used by the Radhanites in their journeys; all four began in the Rhone Valley in southern France and terminated on China's east coast. 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.

Text of Ibn Khordadbeh's account

In his Book of Roads and Kingdoms (, Kitāb al-Masālik wa-l-Mamālik), Ibn Khordadbeh listed four routes along which Radhanites traveled in the following account.

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.
