The Architecture of Mercian Diplomatic Hegemony (757–821) →
“How did the formulas and royal styles of King Offa and King Coenwulf reflect the political dominance of Mercia over Kent, Sussex, and the Hwicce?”
During the eighth-century Mercian supremacy, Offa discarded provincial royal titles in favour of overarching styles like "rex Anglorum" and reduced former kings of the South Saxons and Hwicce to "subreguli" or "duces" in attestation lists.
Maledictions of Scriptoriums: Rochester vs Christ Church Sanctions →
“Did monastic archives develop distinct regional formulas for threats of eternal damnation, or did scribes draw from shared patristic and biblical florilegia?”
Charters consistently conclude with severe sanctions (curses/anathemas) condemning infringers to the company of Judas, Dathan, and Abiram in the lowest abyss of hell, unless they make restitution before death.
From Latin Landmarks to Old English Perambulations →
“At what point in the eighth and ninth centuries did the recording of estate bounds transition from brief Latin descriptions into detailed Old English perambulations?”
While early seventh-century Kentish diplomas describe bounds in terse Latin, eighth-century Mercian and ninth-century West Saxon grants incorporate extensive vernacular landmarks (burh-geat, herpað, dic, burna).
The Charters of King Alfred: Survival, Forgery, and Chancery Form →
“Why do so few royal diplomas survive in the name of King Alfred the Great compared to his father Æthelwulf, and what does this reveal about late 9th-century administrative disruption?”
Only around sixteen charters survive in Alfred’s name (S 342a–357). Alex Burghart’s doctoral research demonstrated that the Scandinavian invasions severely disrupted scriptoria and chancery production in Wessex.
The Introduction of the Incarnation Era in Insular Diplomas →
“How rapidly was Dionysian Anno Domini dating adopted in Anglo-Saxon diplomas following its promotion by the Venerable Bede in 731?”
Early diplomas relied primarily on the fifteen-year Roman Indiction and episcopal or regnal years. Following Bede’s Historia Ecclesiastica, Anglo-Saxon England became the first western society to use the AD dating system regularly in official legal documents.
Episcopal Precedence and Royal Councils in Canterbury Diplomas →
“What patterns of political and ecclesiastical precedence are revealed by the strict hierarchy of witness lists in councils at Clofesho, Chelsea, and London?”
Attestation lists follow rigid legal order: the King, Queen, Archbishop, diocesan bishops in seniority, abbots, and ealdormen (principes/duces). Changes in order frequently signal political upheavals or contested royal accessions.
