In England, the West Country sees religiously motived risings under the leadership of Humphrey Arundel, seeking to restore the Catholic liturgy in the face of the recent imposition of the Book of Common Prayer. For those in the west of Cornwall at least, one of the causes of offence in this new obligatory prayer book was that it was entirely in English, while the people of these parishes still used Cornish in their everyday life and had been accustomed to use it in church. The rebels form several armies, which continue to move eastwards until they are finally suppressed in August.
