How did the English Reformation differ from Luther's break with the Catholic Church?

While the Protestant Reformation started by Martin Luther was based on principle---a response to the corruption of the Catholic Church and attempt to turn Christian religion back to focusing on the words of the Bible---the English Reformation was less principled and much more strategic.

King Henry VIII of England was concerned about the Pope gaining too much influence on England, and thereby threatening his own power. But the last straw was when the Pope would not allow him to annul his Catholic marriage so that he could remarry and father an heir.

In response, Henry declared himself the head of a new church, the Church of England, thus giving himself control over marriage law and in particular his own marriage. In terms of theology the Church of England was largely the same as the Catholic Church, much more so than the other Protestant sects that were emerging at the time.
