Answer:
To consolidate power to themselves
Step-by-step explanation:
The emergence of palaces was a move by the kings to fortify their monarchies. The kings were often worried about how to perpetuate their power. In addition, they were concerned about how their children and families would live after they were gone. Thus, after the defeat of the pope by Napleon's general, the church had no more power to control monarchies. They concentrated the power to themselves.
