Cornish Rebellion of 1497

The Cornish Rebellion of 1497 (Cornish:Rebellyans Kernow) was a popular uprising by the people of Cornwall in the far southwest of Britain. Its primary cause was a response of people to the raising of war taxes by King Henry VII on the impoverished Cornish, to raise money for a campaign against Scotland motivated by brief border skirmishes that were inspired by Perkin Warbeck's pretence to the English throne. Tin miners were angered as the scale of the taxes overturned previous rights granted by Edward I of England to the Cornish Stannary Parliament which exempted Cornwall from all taxes of 10ths or 15ths of income.
