The controversy over the fortunes of English towns in the later middle ages has tended to generate more heat than light. Much of the evidence employed in this debate has been drawn from the larger English towns, but this essay suggests a widening of the research agenda to include a more systematic assessment of small towns and village markets. Although weakened by the reduced demand for grain after the Black Death, these places competed for the growing local trade in basic consumer goods. Evidence from northeast Hertfordshire reveals that this competition resulted in a significant restructuring of the hierarchy of local marketing centres, and a decline in the ability of seigneurial and urban authorities to regulate trading activity.
