Normans, Jews and Medieval Traders, c1066–c1500

Three Migrant Stories, One Period

Between c1066 and c1500, three very different migrant groups shaped England: the Normans, who arrived as a conquering elite; Jewish communities, brought across by William the Conqueror as royal financiers; and European traders and craftsmen, including the Hanseatic merchants of London’s Steelyard. Reading them side by side teaches the heart of the thematic study — that migration in the same period can be elite, forced, religious or economic all at once. The four key factors (institutions, religion, economic influences, attitudes) all worked differently for each group.

The Normans After 1066

The Norman Conquest of 1066 was a wave of elite migration. William the Conqueror distributed land to perhaps 200 Norman barons, displacing almost the entire Anglo-Saxon landowning class. Domesday Book (1086) records that around 95% of land was held by Norman lords by William’s death. The Norman elite was not, however, a single ethnic group: it included Bretons from western France, Flemings from modern Belgium, and other northern French speakers. Calling them simply ‘the French’ misses how mixed the conquering force actually was.

Norman migration reshaped landownership, the towns, the wool industry and the Church. Romanesque cathedrals replaced Anglo-Saxon ones at Durham, Canterbury and Winchester; the Domesday survey put royal taxation on a new institutional footing; the legal idea of feudal tenure took hold. Norman French became the language of court and law, while ordinary people continued to speak English. Over the centuries the two languages mingled to produce Middle English — one of the deepest impacts of any wave of migration on this island.

Jewish Communities and the Crown

William the Conqueror also brought the first Jewish migrants to England, encouraging them to settle in London and other towns. Jewish communities played a crucial economic role because Christian teaching in this period prohibited Christians from charging interest on loans. Without Jewish moneylenders, the crown could not finance castle-building, military campaigns and royal administration. Aaron of Lincoln (d. 1186) became one of the wealthiest men in England by lending to the crown, the great barons and even Cistercian monasteries.

Jewish migrants in England held the unique legal status of belonging directly to the king. They were taxed through tallage — a special tax that could be raised at royal will, unlike the more limited taxes paid by other subjects. This made Jewish communities both protected and exposed: protected by royal interest, but exposed when popular hostility flared. In March 1190, antisemitic violence climaxed in the massacre of Jews at Clifford’s Tower in York. About 150 Jewish people died there on 16 March, most of them by their own hand rather than surrender to the mob outside. The events of 1190 sit alongside Aaron of Lincoln’s wealth as evidence that medieval Jewish life in England mixed royal protection with episodes of devastating violence.

European Traders and the Hanseatic Steelyard

Alongside Norman lords and Jewish financiers, European traders and craftsmen made up the third strand of medieval migration. Many Flemish weavers settled in Norwich, London and the south-east, where the wool industry pulled in skilled labour. The most famous example of European trade migration was the Hanseatic Steelyard in London. Hanseatic merchants ran a fortified trading enclave on the north bank of the Thames, near London Bridge. Their London base is first recorded as a single Hanseatic organisation in 1282, and Edward I confirmed its trading privileges in the Carta Mercatoria of 1303. From the Steelyard, they imported timber, furs, wax, fish and grain from northern Europe and exported English wool and cloth.

Like Jewish migrants, Hanseatic merchants held a special legal status — the medieval status of alien. Aliens paid higher customs duties, could not own land freely, and lived under their own community rules in defined enclaves. The Steelyard merchants ran a self-governing community with their own warehouses, dining hall and even a small chapel. They prospered until 1598, when Elizabeth I finally revoked their privileges — but for over three centuries they were the most visible foreign-trading community in London.

The Black Death and Migration

The Black Death of 1348–49 killed perhaps a third of the English population and reshaped migration patterns. Survivors moved from villages to towns where labour was suddenly scarce and wages were rising. Skilled craftsmen, especially weavers and dyers, were actively recruited from the Low Countries to fill gaps. The plague did not stop migration — it concentrated it in growing towns and increased demand for European craftspeople. By 1450, around 1.5% of England’s population was made up of recorded aliens, with concentrations in London, Norwich and Southampton.
