What counts as long-distance trade
Most medieval exchange was local: grain, cloth and tools moved a few miles to the nearest market. Long-distance trade was a smaller part of the whole economy by volume, but it mattered far more than its size suggests. It supplied things a region could not produce, financed cities, enriched rulers through tolls and linked Europe to Africa and Asia. This article focuses on what moved, who moved it and the places and associations that made it possible.
Luxury goods and bulk goods
It helps to separate two kinds of cargo. Luxuries were light, valuable and worth carrying a long way: silk, fine dyes, precious stones, perfumes, incense, ivory and above all spices such as pepper and cinnamon. Most of these came from Asia or the Middle East, passing through several sets of traders before reaching Europe. A small shipment could be worth a great deal, which helped cover the expense and risk of the journey. The demand was strongest among the wealthy and the church, which used incense and costly cloth in worship.
Bulk goods were cheaper per unit, so they traveled best by water. Grain, timber, salt, wine, fish, wool and cloth were the staple cargoes of much medieval shipping. Salted herring from the North Sea and Baltic, for example, fed buyers far inland and was especially valuable in a religious culture that prescribed many days of fasting from meat. Wine moved from southwestern France and the Rhine to northern consumers, and salt from coastal evaporation works to inland towns.
Many regions specialized. England was known for wool, Flanders for finished cloth, Scandinavia and the Baltic for furs, amber and timber, the Mediterranean for olive oil, dried fruit and sugar, and parts of Central Europe for metals. Trade existed because these differences made swapping profitable.
Ports and the water road
Water transport was generally cheaper and faster than carrying goods by cart or pack animal over rough roads. Rivers, coasts and seas formed the main arteries. The Rhine, Rhone, Danube and other rivers carried goods deep into the continent, while ports gathered cargoes from the surrounding country and handed them to ships.
A medieval port was more than a dock. It had warehouses, customs officials, weighing houses, money-changers and inns. Merchants relied on brokers who spoke local languages and knew local customs. Ports in Italy, such as the ones tied to the Venetian republic and Genoese merchants, built extensive networks reaching east to Constantinople and the Levant. Northern ports connected Flanders, England, the Baltic and the Rhine.
Ship design changed over the period. Larger cargo ships such as the cog, a high-sided single-masted vessel common in northern waters, could carry more than earlier craft, which helped bulk trade grow. Mediterranean traders used galleys for valuable goods and rounder sailing ships for heavier ones. Ships remained vulnerable to storms, shipwreck and piracy, so insurance-like arrangements and the splitting of cargoes among several vessels became common ways to share risk.
Land routes and caravans
Overland trade was slower and more expensive but reached places ships could not. Pack animals crossed the Alps, merchants followed river valleys and roads linked fair towns. In the wider world, camel caravans crossed deserts. The trans-Saharan trade carried West African gold, and in return brought salt and goods from North Africa. Eastern goods also traveled over Central Asia during periods when the Mongols maintained relative order, an era sometimes called the Pax Mongolica.
Tolls were a constant feature of land travel. Every lord whose territory a route crossed could charge for passage and for the use of bridges. Merchants complained of these charges, but they also paid for safe conduct and road maintenance in some cases. Brigands and uncertain weather added to the risks.
Trading leagues and associations
Merchants discovered that traveling in groups, with common rules and legal protection, made trade safer. Some formed partnerships for a single voyage. Others joined permanent associations of merchants from the same town or region, which negotiated privileges abroad, maintained lodgings and warehouses and defended their members in disputes.
The most famous example in northern Europe is the Hanseatic League, a network of merchant communities and towns around the North Sea and Baltic that cooperated over trade privileges and security. In the Mediterranean, Italian cities pursued similar goals through their governments, securing trading quarters and treaties in distant ports. In the east, Novgorod republic merchants dealt with both Baltic traders and the Russian interior.
These bodies were not empires. They did not rule territory in the manner of a kingdom, and their power depended largely on the value of the trade they controlled and their ability to negotiate or, at times, apply pressure through trade embargoes.
Money, credit and information
Large-scale trade required ways to move value. Carrying heavy coin was dangerous, so merchants used credit, account books and eventually bills of exchange, which allowed payment in one place to be settled in another. Italian firms were especially active in developing these practices, with branches in several countries.
Information was also a commodity. A merchant needed to know where prices were high, which routes were safe and whether a ruler had changed the tolls. News traveled slowly, largely through letters and messengers, so agents had to be trusted to make decisions on their own.
Limits and effects
Long-distance trade was vulnerable to wars, plague, political upheaval and changes in the price of precious metals. The Black Death disrupted ports and populations in the fourteenth century, and political changes in the Middle East and Central Asia shifted the profitability of eastern routes. Yet the overall effect of such commerce was lasting. It helped create wealthy mercantile cities, supported banking, spread products and ideas, and tied together regions that might otherwise have had little contact. Medieval Europe was far from isolated, and its economy was always tied to larger networks.
