How did the actions of Henry VIII lead to increased secularism, and possibly the spark of absolute monarchies?
By establishing the Church of England, King Henry VIII made himself the head of the Church as well as the state in England.
This supported the theme that the Church is decidedly very involved in the matters in the state and politics, worldly issues rather than strictly spiritual ones. (secularism)
Additionally, this action consolidated Henry's power giving him influence over the spiritual aspects of people's lives as well as the worldly ones without having to share power with any other authority, like the pope. (absolutism)
