Final answer:
The power of an absolute monarch can be weakened by opposition groups, economic crisis, and external factors.
Step-by-step explanation:
The power of an absolute monarch can be weakened by several factors. One factor is the rise of opposition groups or movements that challenge the monarch's authority. These groups may advocate for democratic reforms or advocate for the redistribution of power.
Another factor is economic crisis or mismanagement, which can lead to discontent among the population and weaken the monarch's legitimacy.
Additionally, external factors such as war or invasion can also weaken the power of an absolute monarch, as it may lead to loss of territory or resources.
