In a period where politics could not be separated from dynasty and the personal relationships between individuals were crucial to government, women often played a key role in diplomacy. This was certainly the case in relations between England and Scotland in the medieval period, with sisters, daughters and cousins of English kings regularly being dispatched north of the border to forge links through marriage with the Scottish kings. This talk draws on records at The National Archives and elsewhere to illuminate the roles that these women played and discuss what light they can shed on Anglo-Scottish relations.Dr Jessica Nelson works at The National Archives specialising in the high medieval period and her research interests include royal women and queenship.
