The Pilgrimage of Grace (October 1536–February 1537) is a popular rising in York, England during 1536, in protest against Henry VIII's break with the Roman Catholic Church and the Dissolutioin of the Monasteries, as well as other specific political, social and economic grievances.
It is done in action against policies initiated by Thomas Cromwell.
Technically the term Pilgrimage of Grace refers specifically and inclusively to the uprising around York, though sometimes it is used in relation to the risings in general which took place around northern England; first from Lincolnshire, twelve days before the actual Pilgrimage of Grace.
