Dentdale was the first outbreak of real English resistance to the Reformation of Cromwell and Henry VIII to resemble the Irish rebellion of summer 1534.21 For almost a month, the Dentdale men kept to their own territory, but others began imitating their example. Dentdale pioneered an aspect of the northern troubles which became characteristic, the taking of oaths, and it eventually provided a full-scale contingent joining the Pilgrimage by 21 October, a fortnight after the big outbreak in south-east Yorkshire around 8 October.
