Ironically, while Henry claimed for himself powers never
claimed before by any English king, the underlying story of his
political revolution is not his personal lust for power, but rather
his unprecedented employment of Parliament in his service. The
1534 Act of Supremacy established the absolute sovereignty of the
king in Parliament. Although this did not mean that Parliament
conferred sovereignty upon Henry, it did mean that England's monarchy
was a constitutional monarchy, and not an absolute one as was often
the case in nations such as France and Spain.
Practically speaking, Henry had little choice in employing
Parliament as he did in his reformation. He could not break all
of England's ties to Rome by himself, and he needed the force of
parliamentary law to see his plans through to success. It was fortunate that
Henry had Cromwell at his side to employ Parliament as skillfully
as he did, simultaneously establishing the supreme authority he
desired as King of England and establishing important institutional
groundwork for the future stability and effectiveness of the English
constitution. Parliament was an essential element in Henry's political
revolution.
