During the French occupation of Hesse-Kassel (1806-1813) he stayed with his mother in Berlin. The relationship with his father was bad, because of his father's affair with Emilie Ortlöpp.
Frederick was educated at Marburg and Leipzig. He became co-regent on 30 September 1831, and Prince-elector in 1847. Under influence of his minister Hans Daniel Ludwig Friedrich Hassenpflug he conducted a reactionary policy, which made him very unpopular. He was forced to give in to the demands of the March Revolution, but reinstated Hassenpflug in 1850 after the revolution had been crushed.
In the Austro-Prussian War (1866) he chose the side of Austria. His capital Kassel was occupied by Prussia, and, as a consequence of his refusal to negotiate, he was transferred as a prisoner to Stettin on 23 June. Hessen-Kassel was annexed by Prussia in the same year.
Because of his morganatic marriage, his sons were excluded from succession. He was succeeded, as titular Prince-elector of Hesse, by Prince Frederick William of Hesse, from the house of Hesse-Rumpenheim.
Frederick William morganatically married on 26 June 1831 to Gertrude Falkenstein (Bonn, 18 May 1803 - Prague 9 July 1882), daughter of Johann Gottfried Falkenstein (son of Nicolaus Falkenstein and wife Margarethe Heyss) and wife Magdalena Schulz (daughter of Johann Ludwig Albert Schulz and wife Sophie Krupps).
Gertrude Falkenstein was the former wife (m. Graven-Rheindorf, 30 November 1822) of Lt Karl Michael Lehmann (Bischofswerder, 16 June 1787 - Wandsbek, 1882), whom his father William II made her Her Illustrious Highness Countess of Schaumburg in (1831) and whom he made Princess (Fürstin) of Hanau and to Horowitz in (1853).
They had nine children, some born before marriage, who were also made princes (Prinzen) of Hanau, and granted the style of Serene Highness in 1862. Subsequently, the Prince-elector divorced Gertrud.
