How did parliament erase the existence of a one man rule in England?

Answer 1

Simple, that was through the implementation of the parliament. You see, when the parliament was implemented, the monarch's power began fading away because of the fact that it was being limited by the parliament's power. Parliament makes the entire concrete decisions. Let's take for example, if a king wants to abolish a law such as the slave trade, he cannot entirely abolish that law. Why? because the parliament has to have a say in the abolishing of that law. The parliament has to discuss matters on abolishing that law, the king may be the one who suggested it, but he cannot entirely pass that law; compared to that of an absolute monarchial rule, in which the monarch has absolute powers. So in conclusion, because the parliament was established, the monarch's powers were slowly erasing, until it came to a point wherein (in today's society) the monarch has absolutely no power and all he is merely a symbol of unity among his country.
