Prayer Book Rebellion

The Prayer Book Rebellion or Western Rising was a popular revolt in Cornwall and Devon in 1549. In that year, the first Book of Common Prayer, presenting the theology of the English Reformation, was introduced. The change was widely unpopular, particularly in areas where firm Catholic religious loyalty (even after the Act of Supremacy in 1534) still existed, such as Lancashire. Along with poor economic conditions, the enforcement of the English language led to an explosion of anger in Cornwall and Devon, initiating an uprising. In response, Edward Seymour, 1st Duke of Somerset sent John Russell to suppress the revolt, with the rebels being defeated and its leaders executed two months after the beginning of hostilities.
