Why did the age of the absolutism happen?

Absolutism began during the transition from feudalism to capitalism in the early 17th century. It came about through the concept of the "Divine Right of Kings" meaning that a Kings power came directly from God not from the people, so the ruler is not accountable to them. The monarch had control over every aspect of the government, they had 'absolute power'. Basically absoultism started because of the mindsets of people in the time period, the monarch was chosen by God thus they have the power to rule as they wish.
