Henry VII’s reign had demonstrated that the Crown could live within its normal income, provided it did not go to war.
But Henry had built up surpluses by introducing arbitrary and unpopular methods.
As Henry VIII wanted to be more involved in European diplomacy and also wanted to go to war with France, Henry VII’s surplus was soon used up.
Wolsey was therefore called upon to raise extra revenue. If there were difficulties, it was because warfare was increasingly expensive and the English Crown remained under funded.
