A Welsh chapter, 1145–1312

Following the Norman conquest of parts of south Wales in the late eleventh and twelfth centuries, powerful Anglo-Norman lords such as the FitzTancreds, the de Roches and the Marshals began carving out lordships in Pembrokeshire, Gower and the borderland. Many of these men had crusader kin, and several chose to endow the new military orders with parts of their newly conquered estates. The Templars, founded in Jerusalem in 1119 and formally recognised in 1129, arrived in Wales as beneficiaries of those grants.

The order's first Welsh preceptory was established at Slebech on the Cleddau estuary in Pembrokeshire, on land granted by Wizo the Fleming and his descendants some time before 1150. From that mother house they built up a scattered but coherent estate stretching from north Gower into Carmarthenshire, with dependent granges, mills and a crucial ferry crossing.

The Welsh houses were, above all, working estates. Rents came in from tenant farmers; wool was sold into the export trade; mills ground the grain of surrounding parishes; ferries and pilgrim routes generated tolls. The brethren themselves were few — a preceptor, a handful of knight brothers or serving brothers, chaplains, and the lay staff who did most of the physical work.

None of this required castles. The Templars built simple estate churches and hall-houses, most of which have long since gone. What survives is often the pattern in the landscape: a village plan, a field boundary, a place-name. Templeton in Pembrokeshire — Villa Templi in the medieval rolls — is the clearest example.

On Friday 13 October 1307, King Philip IV of France ordered the arrest of every Templar in his kingdom on charges of heresy. Under pressure from the French crown, Pope Clement V eventually dissolved the whole order by papal bull at the Council of Vienne in 1312. In England and Wales the suppression was less violent than in France, but no less final.

The Welsh Templar estates were seized by the crown and, in 1324, transferred wholesale to the Knights Hospitaller. Slebech continued as a Hospitaller commandery until the Reformation. The ruined church of St John there is, in a real sense, still the last Templar building standing in Wales.

Because there were no crusades on Welsh soil and no dramatic sieges, the Templar record here is unusually calm and documentary. We know the Welsh Templars through charters, extents and rent-rolls, not through chronicles of battle. That makes the story less romantic than the popular image of the order — but arguably more revealing, because it shows what the Templars did for most of their existence: they ran a bank, a farm, and a supply chain.
