Merchants and Trade in the Early Mongol Empire

When Temüjin became Chinggis Khan in 1206, the new empire joined the Mongolian steppe to settled communities in northern China and, through later conquests, Central Asia and the lands around the Caspian and Black seas. Until imperial unity fractured amid succession struggles around 1260, merchants worked within this changing political space. Their business involved moving goods, but also supplying rulers with information, arranging purchases, lending money and helping courts reach distant markets. The broader economy included pastoral households, farming and taxation; this article follows the merchants and financial arrangements that connected those activities.

Routes linked different markets

Trade was already familiar to the Mongol court before the great western campaigns. In 1203, according to Thomas Allsen’s study of the early empire, a Central Asian trader named Asan brought a thousand castrated sheep from Onggüd lands on the northern China frontier to exchange for sable and squirrel skins. The transaction joined herding and fur-bearing regions through a negotiated exchange. It also brought a merchant into contact with Chinggis Khan’s circle before the empire was formally proclaimed.

One of the empire’s routes from the Black Sea coast connected northern furs with goods arriving from the south and east. The Franciscan William of Rubruck, who travelled in 1253, described merchants gathering at Soldaia in Crimea. Traders from Rus and other northern lands brought valuable furs, while other traders carried cotton cloth, silk textiles and spices. At Matrica, near the Don’s mouth, traders from Constantinople sent small boats up the river to buy dried fish. These examples show how ports, river landings and overland routes joined particular producers and buyers; they were not a single continuous market.

Markets also moved with Mongol rulers. Rubruck wrote that a market followed Batu’s camp as it travelled along the Volga. He and his companions could not reach it because they lacked horses and had to walk. On his journey eastward toward Möngke’s court, he found a busy market at Qayaligh, where his party waited twelve days for an official travelling in the same direction. At Karakorum, then the imperial capital in central Mongolia, he passed through a market square in the city’s Muslim quarter. His account shows merchants meeting near both mobile and settled courts, while access depended on transport, location and a traveller’s means.

Commercial knowledge could also serve political purposes. In 1211, Ja‘far Khwaja went into the territory of the Jurchen Jin, the dynasty ruling northern China, to discover the intentions of its ruler. After Mongol forces captured Zhongdu, the site of modern Beijing, in 1215, Ja‘far became the first Mongol-appointed imperial representative there. His path from merchant service to intelligence and administration illustrates how a ruler could use a trader’s knowledge of borders and people.

Elite partners supplied capital

Some merchants worked in an arrangement called an ortoq, a Mongolian form of a Turkic word meaning “partner.” Allsen uses the term for a merchant who conducted business with capital supplied by a Chinggisid prince or court official. The investor provided silver or other resources; the merchant used commercial experience and contacts to buy and sell goods or lend money. A partnership could bring the court a share in trade and give the merchant resources and protection for a venture.

Under Ögödei, who ruled from 1229 to 1241, court investment expanded. A report by two Song envoys visiting Mongolia in the 1230s says that princes and princesses entrusted silver to Muslim merchants, some of whom lent it at interest while others traded goods in several places. The Persian historian Juvayni also recounts that Ögödei supplied capital to an ortoq merchant and later advanced new funds after the man had lost part of the investment. Ögödei’s treasury bought merchants’ goods at generous prices, and the khan explained that his payments helped merchants gain under imperial protection. The court used its wealth to attract traders and supplies, while merchants accepted the risks of purchasing, travel and resale.

Trade could also create a debt owed by the state. During Güyük’s brief reign, from 1246 to 1248, merchants who had served the ruler were owed a large sum. Because the treasury lacked ready cash, the court issued drafts against revenue from provinces. A draft was a written claim to future payment: it allowed a merchant to receive a promise backed by expected tax income instead of immediate silver. This arrangement kept merchants engaged with the court, but it also made the government’s financial commitments visible across the regions expected to provide that revenue.

Loans connected taxes with household needs

Merchants also lent money to people who needed silver before a tax payment came due. The Song envoys’ report describes Muslim merchants lending rulers’ silver to the population, while Allsen’s account of Möngke’s reforms notes that households in northern China again turned to Central Asian lenders after a high household tax was set in 1252. Lending could bridge a mismatch between the date an obligation was due and the time a household could obtain money from its own work or sales. When interest accumulated, however, a loan taken to meet a tax demand could become harder to repay.

Möngke, who ruled from 1251 to 1259, sought to bring this commerce under closer supervision. Allsen reports that merchants were entered in census registers, made liable for regular taxation and stripped of some privileges enjoyed under earlier rulers. Authority tablets called paiza could be used to demand goods or services from local households, while free use of post horses shifted transport costs to communities. Möngke required merchants to return these tablets and ride their own animals.

When merchants asked the new khan to settle the treasury’s accumulated drafts, Juvayni put the obligation at 500,000 silver ingots. Möngke ordered payment from the realm’s funds, despite his ministers’ advice, preserving the court’s outstanding commitments to its traders.

Möngke also told officials to guard against usury and excessive greed. In 1254, the rule that accrued interest must not exceed the original principal was reaffirmed. The cap was intended to limit the growth of a debt, not to end lending. Allsen notes that “lamb interest” continued despite the order: this was interest added to a loan, so a lender could charge further interest on both the original sum and the interest already added.

As succession conflicts divided the empire around 1260, these court policies no longer governed one united political space. The successor states inherited commercial connections but developed their own arrangements.
