The cult of St Cuthbert was central to the regional identity of north-eastern England with its inhabitants termed the haliwerfolc, or ‘people of the saint’ (Cuthbert). The saint became crucial to the liturgical practices and celebrations of Durham's clerical and secular communities as well as being a guarantor of martial victories; usually against the Scots. However, with the cult of saints an early victim of the Reformation launched by Henry VIII in the 1530s, the outlook for St Cuthbert's legacy became increasingly uncertain. Attachment to the saint's memory became inextricably entwined with Durham's pre-Reformation history as commemoration of the cult, rather than the saint, took on more significance. This article looks at how St Cuthbert's historians and other antiquaries regularly manipulated his legend to satisfy different purposes and circumstances; so that completely different perspectives on Cuthbert and his cult have emerged over the centuries since the Reformation. But, throughout the changing interpretations of St Cuthbert's story his significance in Durham remains unchallenged.
