Pilgrimage of Grace

The Pilgrimage of Grace was a revolt in York, Yorkshire in 1536. People protested against England's break with Rome and the Dissolution of the Monasteries. There were also other specific political, social and economic issues they did not like. Technically the term "Pilgrimage of Grace" only refers to the uprising around York, but 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". 
The revolt was caused by Henry VIII's Dissolution of the Monasteries, which caused problems with around 500,000 monks and nuns.
