Medieval Lincolnshire: (1154 – 1485)

Henry II and the return of stability (1154–c. 1180)

When Henry II took the English throne in 1154, the new king ended the civil war between King Stephen and Empress Matilda. Restored royal order allowed Lincolnshire landowners and merchants to resume trading across an already functioning landscape.

The county did not start from nothing. Norman engineers had already cleared the Foss Dyke during Henry I's reign, Boston possessed an active market by 1125, and Lincoln Castle and Lincoln Cathedral stood firmly on the limestone ridge.

The Anarchy had disrupted early trade, but the waterways and markets survived. With the civil war over, merchants moved goods along the rivers with greater regularity, while landowners expanded agricultural output. Peace allowed Lincolnshire to turn existing routes and markets into a major commercial network.

The European wool trade and the rise of Boston (c. 1180–1215)

Across the countryside, Cistercian monasteries became major agricultural landowners. Monks at Kirkstead Abbey and Revesby Abbey organised vast sheep flocks across monastic estates. Lay brothers managed the animals and worked the monastic farms, known as granges.

At Kirkstead's Sheepwash grange, workers gathered large quantities of fleeces beside the River Witham. Labourers loaded the wool onto boats at the adjacent Calscroft riverbank, and boatmen navigated the cargo downstream to Boston.

Smaller secular producers also fed the broader wool economy, sending fleeces along inland waterways. As European demand for English wool grew, Boston expanded rapidly.

Merchants from the Low Countries and other continental markets sailed into the Wash to buy Lincolnshire fleeces. Traders exchanged the wool for imported cloth and luxury goods. By the early 13th century, heavy shipping had turned the River Witham into a major international supply route.

Lincoln grows rich on cloth and commerce (c. 1180–1215)

Inland, Lincoln merchants exported more than raw fleeces. They also traded high-value dyed fabrics. In 1182, royal buyers purchased Lincoln scarlet and green cloth from city markets. Scarlet commanded high prices, placing valuable finished goods alongside raw wool in Lincoln's trade.

Lincoln's Jewish community, recorded by 1159, provided credit to major ecclesiastical and aristocratic clients across England. Aaron of Lincoln conducted extensive financial business from the city. After his death in 1186, the Crown established the Exchequer of Aaron to manage debts owed to him.

Merchants and financiers used their profits to build in stone. Builders constructed the Jew's House around 1170, creating a substantial domestic residence with a first-floor hall and ground-floor shops. The building still stands on the steep hill below Lincoln Castle.

The siege of Lincoln and the lost jewels (1215–1217)

In 1215, King John agreed to Magna Carta to settle disputes with rebel barons. Lincoln received one of the original copies, which survives in the city today.

The Magna Carta settlement failed, triggering the First Barons' War. Rebel barons invited Prince Louis of France to challenge King John for the English crown.

In October 1216, King John's baggage train attempted to cross the Wash at low tide. Wagons became trapped in the marshy sands, and fast-moving water swallowed royal baggage and treasure. King John died shortly afterwards.

By 1217, French and rebel forces controlled Lincoln's streets, while Nicola de la Haye held Lincoln Castle for the royalists. As constable in her own right, Nicola had already defended the walls during a 40-day siege in 1191.

Nicola maintained the defence until William Marshal's royalist army arrived in May 1217. His soldiers breached the northern city walls and defeated rebel forces in the streets, turning the war against Prince Louis and securing the throne for Henry III.

Raising the world's tallest spire (c. 1192–1311)

While merchants traded along the rivers, bishops and masons rebuilt the cathedral on the hill. An earthquake had damaged the Norman cathedral in 1185, and Bishop Hugh of Avalon initiated a major Gothic rebuilding programme in the 1190s.

The construction required generations of skilled labour. Masons quarried limestone, carpenters raised timber scaffolds, and lead-workers sealed the roofs to build the new nave and transepts.

The work continued long after Bishop Hugh died in 1200. Pilgrims travelled to St Hugh's shrine, bringing donations that helped fund further expansion.

When the central tower collapsed in the 1230s, masons cleared the rubble and began rebuilding. Between 1256 and 1280, stone-cutters built the Angel Choir to house the shrine.

In the early 14th century, masons heightened the central crossing tower. Finally, in 1311, builders crowned the tower with an enormous lead-covered timber spire.

Reaching an estimated height of 160 metres, the spire altered the skyline of the Lincoln Edge. Lincoln Cathedral became reputedly the tallest building in the world, creating a landmark visible for miles across the flat fens.

Boston rivals London in the wool trade (c. 1279–1315)

By the late 13th century, Boston handled around a third of all English wool exports. Customs records from 1279 onwards show more than 9,000 wool sacks leaving the quaysides annually.

Boston drew fleeces not just from Lincolnshire, but from across the wider Midlands. The port competed directly with London at the highest level of English commerce.

Merchants associated with the Hanseatic League connected Boston directly to the North Sea and Baltic trading world. By around 1260, they had established a local trading depot, or steelyard, in the town.

Italian merchants from Florence, Lucca and Piacenza also established permanent operations along the River Witham. Foreign traders attended the annual Boston Fair, buying raw wool and unloading imported goods onto the docks.

Heavy shipping transformed the waterfront as merchants built extensive timber wharves, granaries and wine cellars along the river. By 1304, Boston exported over 10,000 sacks annually, representing wool from nearly 2.5 million sheep. Those shipments connected Lincolnshire's sheep pastures directly to continental weaving towns.

The double blow of famine and plague (1315–1350)

From 1315 to 1317, persistent heavy rain ruined harvests and flooded pastures. The extreme weather triggered the Great Famine, leaving livestock without enough fodder.

A major bovine pestilence followed in 1319, killing cattle and thinning the sheep flocks that supplied the wool trade. The loss of crops and livestock devastated the rural economy, leaving the surviving population vulnerable.

Then, in 1349, the Black Death struck the county. At Thornton Abbey, monks buried at least 48 men, women and children in a single mass grave.

The victims' teeth preserved the Yersinia pestis bacteria. Across Lincolnshire, individual settlements suffered severe population loss. Taxation records for Riseholme show a 40% relief granted in 1352 because of the devastation. As labourers died, fields went unploughed and crops unharvested.

Empty villages and the decline of Boston (c. 1350–1485)

With labour scarce, surviving peasants used their bargaining power to demand higher wages. Older forms of servile control did not disappear immediately.

Spalding Priory continued tracking serfs and collecting payments well after the Black Death, but traditional manorial controls slowly weakened.

Without enough workers to maintain the fields, rural settlements such as Atterby and Riseholme shrank or emptied entirely. Abandoned house plots remained behind, although depopulation had several causes beyond the plague alone.

Boston continued trading, but fewer wool and cloth shipments moved through the docks. Hanseatic merchants continued trading through Boston as progressive silting of Boston Haven increasingly obstructed deep-water shipping. Large vessels were forced away from the quaysides.

During the Wars of the Roses, royal artillery routed a rebel army at the Battle of Losecoat Field in 1470. In 1485, the Battle of Bosworth established the Tudor dynasty.

By 1485, Boston's great wool exports had diminished, but the wealthy abbeys, parish churches and religious communities built during the boom remained deeply rooted in the landscape.
