The minority of Henry VI compelled the English governing cadre, faced with the heavy burden of his predecessor’s foreign conquests and unfinished wars, to clarify its notion of ministerial responsibility, a process which can be observed through the internal council memoranda which have occasionally survived. This new genre of documentation, terse and practical in tone and usually in the vernacular, is common to most European polities from the second decade of the fifteenth century, and seems to replicate closely the rhythm of the spoken word; it can therefore expose the underlying values of councillors which more artfully confected documents keep hidden. Councillors’ memoranda reveal a sense of obligation sharpened by recently articulated notions of equity and of private conscience, in the wake of Henry V’s vigorous stimulus to lay religion, and show that the notions of public duty learnt in his service survived through the reign of his successor.
