Why did Louis XIV, Peter the Great, and Frederick the Great all build or expand the state bureaucracy?

to remove the possibility of peasant revolts
to expand their territory and foreign influence
to increase the power of the nobility
to increase national centralization of power

The correct answer is: to increase national centralization of power.

Louis XIV, Peter the Great, and Frederick the Great all believed in absolute monarchies and sought to consolidate power in their respective states. By building or expanding the state bureaucracy, they aimed to increase their control over various aspects of governance, including administration, economy, and military. This allowed them to establish centralized authority, reduce the power of nobility and local officials, and strengthen their rule.
