Frederick William III of Prussia

Frederick William was born in Potsdam on 3 August 1770 as the son of Frederick William II of Prussia and Frederica Louisa of Hesse-Darmstadt. He was considered to be a shy and reserved boy, which became noticeable in his particularly reticent conversations, distinguished by the lack of personal pronouns. This manner of speech subsequently came to be considered entirely appropriate for military officers. He was neglected by his father during his childhood and suffered from an inferiority complex his entire life.

As a child, Frederick William's father (under the influence of his mistress, Wilhelmine Enke, Countess of Lichtenau) had him handed over to tutors, as was quite normal for the period. He spent part of the time living at Paretz, the estate of the old soldier, Count Hans von Blumenthal, who was a tutor and guardian of his brother, Prince Henry. They thus grew up partly with the count's son, who accompanied them on their Grand Tour in the 1780s. Frederick William was happy at Paretz, and for this reason, in 1795, he bought it from his boyhood friend and turned it into an important royal country retreat. He was a melancholy boy, but he grew up pious and honest. His tutors included the dramatist Johann Jakob Engel.

As a soldier, he received the usual training of a Prussian prince, obtained his lieutenancy in 1784, became a lieutenant colonel in 1786, a colonel in 1790, and took part in the campaigns against France of 1792–1794. On 24 December 1793, Frederick William married Louise of Mecklenburg-Strelitz, with whom he had ten children. In the Kronprinzenpalais (Crown Prince's Palace) in Berlin, Frederick William lived a civil life with a problem-free marriage, which did not change even when he became King of Prussia in 1797. His wife Louise was particularly loved by the people of Prussia, which boosted the popularity of the whole House of Hohenzollern, including the King himself.
