Through Crime and Potsdam

Born in Berlin, he was raised by the Huguenot governess Marthe de Roucoulle. His political awakening occurred during the Great Northern War's plague outbreak in Prussia, leading to his challenge against corruption and inefficiency in government. He initiated reforms, especially in the military, doubling the Prussian Army, and increased the officer corps to 3,000. A believer in absolute monarchy, he focused on state development and financial reorganization, imposing taxes and stringent regulations on public servants. He made efforts to reduce crime, corruption and centralized his authority during his reign of 27 years, cementing Prussia as a regional power.

Despite his effective rule, he had a harsh nature, exacerbated by his health issues. He engaged in colonial affairs, but prioritized military expansion over colonial investments. His notable decisions included selling Prussian overseas colonies and the foundation of the Canton system, as well as the conquest of the port of Stettin.

His death in 1740 marked the end of a reign characterized by military and administrative reform. He was succeeded by his son, Frederick the Great.

Early years

Frederick William was born in Berlin to King Frederick I of Prussia and Princess Sophia Charlotte of Hanover. During his first years, he was raised by the Huguenot governess Marthe de Roucoulle. When the Great Northern War plague outbreak devastated Prussia, the inefficiency and corruption of the king's favorite ministers and senior officials were highlighted. Frederick William with a party that formed at the court brought down the leading minister Johann Kasimir Kolbe von Wartenberg and his cronies, following an official investigation that exposed Wartenberg's huge-scale misappropriation and embezzlement. His close associate August David zu Sayn-Wittgenstein-Hohenstein was imprisoned at Spandau Citadel, fined 70,000 thalers and banished subsequently. The incident exerted great influence on Frederick William, making him resent crime, corruption, wastage and inefficiency and realize the necessity of institutional reform. It also became the first time he actively participated in politics. From then on, Frederick I began to let his son take more power.
