How did Frederick William’s reforms lay the foundations for Prussian absolutism?

Frederick William, the Great Elector, laid the foundations for Prussian absolutism primarily by centralizing authority and diminishing the power of the provincial estates. His reforms were driven by the necessity of maintaining a standing military, which became the core institution of his state.1

Key aspects of his reforms included:

• Standing Army: By organizing his own military force, Frederick William created an institution that allowed him to combat the traditional privileges of the estates. This army became the foundation for the powerful Prussian military machine of the 18th century.1
• Fiscal Control: He successfully forced provincial estates to support the army independently of their traditional tax appropriations. In the latter half of his reign, he removed control over taxation and finances from the estates entirely.1
• Bureaucratic Development: By centralizing financial resources and administration, he established an officialdom that was dependent solely on the sovereign.1

These measures created a state characterized by a standing army, fixed taxes, and a centralized bureaucracy, effectively shifting power from local nobility to the monarch and setting the stage for the later Prussian absolute monarchy.1
