The Pilgrimage of Grace was a popular revolt beginning in Yorkshire in October 1536, before spreading to other parts of Northern England including Cumberland, Northumberland, Durham and north Lancashire, under the leadership of Robert Aske. The "most serious of all Tudor period rebellions", it was a protest against Henry VIII's break with the Catholic Church, the dissolution of the lesser monasteries, and the policies of the King's chief minister, Thomas Cromwell, as well as other specific political, social, and economic grievances.

Yorkshire is an area of Northern England which was historically a county. Despite no longer being used for administration, Yorkshire retains a strong regional identity. The county was named after its original county town, the city of York.
