In 1525 Henry VIII of England wanted to mount an invasion of France  since the King of France, Francis I, had been captured by Holy Roman Emperor Charles V at the Battle of Pavia in 1525. Henry required additional funds of £800,000, so to gain said money Wolsey resorted to the Amicable Grant. The English Parliament was at this time unlikely to support war, since it was proving to be expensive. Furthermore, Henry's previous French endeavours, which had occurred in 1522 and 1523, had proved less than successful.
