The Soldier King, Friedrich Wilhelm I, transformed the Prussian state through radical administrative centralization and military expansion between 1713 and 1740. Born in Berlin in 1688, he spent his twenty-seven-year reign dismantling the corrupt practices of his predecessor’s court, imposing rigorous financial discipline upon the monarchy, and laying the institutional foundations for Prussia’s future regional dominance.
Early Political Formation
Raised by the Huguenot governess Marthe de Roucoulle, the future monarch experienced a political awakening during the Great Northern War. Witnessing the devastation of a plague outbreak, he observed the catastrophic inefficiency of his father’s administration. Alongside a faction at court, he successfully challenged the influence of minister Johann Kasimir Kolbe von Wartenberg. The resulting investigation exposed massive embezzlement, leading to the banishment and heavy fining of associates like August David zu Sayn-Wittgenstein-Hohenstein. This period fostered his lifelong disdain for corruption and wastage, shaping his commitment to absolute monarchy.

Upon ascending the throne in 1713, Friedrich Wilhelm I immediately dismissed the Cabinet of Three Counts to rectify the state’s ruined finances. He implemented a strict regulatory framework for public servants, codified in a manual comprising 35 chapters and 297 paragraphs. Those failing to meet attendance requirements faced severe penalties, including loss of pay or dismissal. Simultaneously, he expanded the military from 38,000 men to 80,000 by 1740, creating the Canton system and introducing iron ramrods to increase infantry efficiency. While prioritizing the army, he also reclaimed marshes, stored grain to stabilize supply during shortages, and encouraged agriculture and commerce.
Colonial and Social Policy
The king maintained a narrow focus on state revenues, preferring domestic development over colonial ventures. In 1717, he revoked the charter of the Brandenburg Africa Company and sold the Brandenburg Gold Coast to the Dutch West India Company to fund army expansion. Socially, he invited Dutch craftsmen to the new Dutch Quarter in Potsdam and supported the migration of 20,000 Salzburg Protestants to depopulated East Prussian lands. Despite his effective governance, his temperament remained volatile, aggravated by obesity, gout, and stomach pains linked to porphyritic disease.
