Because new noble called for a policy that was conducive to the development of capitalism and restricted kingship; The old aristocracy demanded absolute monarchy and retained the feudal system. However, the constitutional monarchy established after the glorious revolution retained the ownership of the king and a large area of land, but restricted the royal power and stipulated that the king's decision could not contradict the parliament. The king is actually in a state of ignoring the government towards the DPRK, and the parliament has also passed many resolutions on developing capitalism. To sum up, the constitutional monarchy established after the glorious revolution met some requirements of new noble and the old nobles, but it also met the opposite of their requirements, so it was the result of compromise between the old and new nobles.
