Records of the Medieval Duchy of Lancaster
The Duchy of Lancaster
The earldom of Lancaster was created in 1267 by King Henry III for his second son, Edmund. This came in the aftermath of England's first revolution, in which Simon de Montfort, Earl of Leicester, had seized power. The new earldom incorporated the Honour of Lancaster, based at Lancaster Castle, and the earldoms of Leicester and Derby, seized from disinherited Montfortians. To this great estate, the earldoms of Lincoln and Salisbury were added, in 1311, and then the Honour of Clitheroe, in 1348. This was an extensive, private land holding that brought swathes of the country's population and lands under the earl's jurisdiction. In 1351, the title 'Duke of Lancaster' was first bestowed on Henry Grosmont. His daughter Blanche married John of Gaunt, the second Duke of Lancaster. The heir to the Duchy, Henry Bolingbroke, seized the English throne in 1399, becoming Henry IV. He decreed that the Duchy should be held separately from all other Crown possessions and descend through the monarchy as a private estate. Today the estates of the Duchy belong to His Majesty the King and cover more than 18,228 hectares across England and Wales.
The Great Cowcher
In around 1402, King Henry IV commissioned the Great Cowcher Book: a record of land, titles and rights within the vast Duchy of Lancaster. The Cowcher includes copies of 2,433 documents written in Latin and French. This makes it second only to William the Conqueror's Domesday Book as a record of medieval landholding and the lives of ordinary people and communities in Medieval England. Unlike Domesday, though, it is richly illuminated. The scribes used precious inks to decorate the text and create captivating drawings of the earls and dukes across the centuries, as well as heraldic banners. The image here accompanies the Cowcher's first entry: a copy of Henry III's grant of the Honour, county, castle and town of Lancaster to his son in 1267. It shows the king granting the original charter in 1267, reimagined in early fifteenth-century fashion.
Research at Lancaster
The Great Cowcher Book sits within the Duchy of Lancaster's archive, housed at The National Archives (TNA): one of the largest private archives of medieval documents in the world. Lancaster historians are working with colleagues at TNA and the University of Lincoln to explore these records. What can they tell us about how the people of the duchy's lands experienced the political and military strife of their day, the several civil wars of the thirteenth to fifteenth centuries and the Anglo-Scottish wars, which ravaged much of northern England? How can they reveal the environmental history of this era: how communities exploited their landscapes, and coped with plague, famine, and climatic shifts? At Lancaster, researchers are leading targeted projects to explore these questions. Dr Sophie Thérèse Ambler has been leading research to survey and calendar the Duchy's Lancashire records 1267-1348 held at TNA, funded by the Society of Antiquaries of London. Professor Fiona Edmonds has led a project to complete the transcriptions and translations of Duchy's thirteenth- and fourteenth-century records pertaining to the forests of Lancashire (this initiative develops transcription work originally started by volunteers from the Ranulf Higden Society). These records are illuminating sources for settlement and society in medieval Lancashire, and the project has been funded by the Medieval Settlement Research Group.
Light Up Lancaster
Researchers at Lancaster have worked with the Duchy of Lancaster, the Regional Heritage Centre and projection artists Illuminos to create the centrepiece for Light Up Lancaster 2023: a monumental sound and light display at Lancaster Castle, showcasing the history of the Duchy and the Great Cowcher at its ancestral home.
Over the nights of 2-4 November, the Duchy's medieval archive — from the magnificent illustrations from the Great Cowcher to the forest records and charters — will light up the Castle walls, amidst a dramatic soundscape including readings from the Great Cowcher.
This display will be an innovative and exciting way to engage a wide audience with Lancaster's research. The event is free and open to all. For more information visit The Duke's website.

Lancaster Castle and Northern English History: The View from the Stronghold
This award-winning online course was produced by the Regional Heritage Centre and supported by the Duchy of Lancaster and Lancaster University's Information Systems Services. It takes an innovative approach to exploring history, focusing on Lancaster Castle as a microcosm of broader trends. This fascinating location provides a wealth of evidence from the remains of Roman forts to its life as a prison and visitor attraction. Our engaging educators respond to the castle and its surroundings in relation to their research interests, such as medieval Anglo-Scottish wardare, the witchcraft trials of the seventeenth century and the achievements of prison reformers. Join us to uncover this castle's vital role in northern English history over many centuries.
