Frederick William I (Friedrich Wilhelm I) (August 14, 1688 – May 31, 1740) of the House of Hohenzollern, was the King in Prussia and Elector of Brandenburg (as Frederick William II) from 1713 until his death. He is popularly known as "the Soldier-King" (der Soldatenkönig).
The King acquired a reputation for his fondness for military display, leading to his special efforts to hire the tallest men he could find in all of Europe for a special regiment nicknamed the Potsdam Giants.
Frederick William's contributions to the state of Prussia primarily consisted of civil service reforms, developing the international reputation of the Prussian military, and increasing the overall efficiency and discipline of his military, which in turn placed Prussia as an entity on a par with Early Modern France, the Kingdom of Great Britain, and other politically dominant states in Europe during the 18th century.
During his reign, Frederick William I did much to centralize and improve Prussia. He replaced mandatory military service among the middle class with an annual tax, established primary schools, and resettled East Prussia (which had been devastated by the plague in 1709).
Frederick William was an extremely able administrator. He opposed all superfluous spending, so long as it did not concern his army. Frederick William paid the consumer tax he himself had imposed, and no candles were left burning at court. He lived frugally and worked hard and tirelessly for the welfare of his people. He encouraged farming, reclaimed marshes, stored grain in good times and sold it in bad times. He dictated the manual of Regulations for State Officials, containing 35 chapters and 297 paragraphs in which every public servant in Prussia could find his duties precisely set out. A minister or councillor failing to attend a committee meeting would lose six months' pay. If he absented himself a second time, he would be discharged from the Royal service.
In short, Frederick William was extremely concerned by every little aspect of his country so that it suited the needs of his army. His rule was absolutist and he was a firm autocrat. He practiced rigid economy, and at his death there was a large surplus in the treasury which was kept rather bizarrely in his basement. The Prussian army was made an efficient instrument of war. Although Frederick William built up one of the most powerful armies in Europe and loved military pomp, he was essentially a peaceful man. He intervened briefly in the Great Northern War, but gained little territory.
