Which explains a difference between the constitutional monarchy established in England and absolute monarchy established in Spain

The powers among the political leaders in England were separated and shared, while the Spanish monarch held complete power over the people.

A constitutional monarchy, means there is still a "monarch" but similar to American style government they have to follow a set of rules based on a written or un-written constitution. Absolute monarchy is when a ruler does not have to follow a set of rules listed out by a written or in-written constitution.
