Models of Authority: Scottish Charters and the Emergence of Government is a resource for the study of the contents, script and physical appearance of the corpus of Scottish charters which survives from 1100–1250. Through close examination of the diplomatic and palaeographic features of the charters, the project will explore the evidence for developments in the perception of royal government during a crucial period in Scottish history.
