Early life[edit]
Frederick was born at his family's Panker Castle, in Plön, Holstein. He was the third son of Frederick William of Hesse, Landgrave of Hesse, and his second wife Princess Anna of Prussia, daughter of Prince Charles of Prussia and Princess Marie Louise of Saxe-Weimar-Eisenach. Frederick William, a Danish military officer, had been one (and perhaps the foremost) of the candidates of Christian VIII of Denmark in the 1840s to succeed to the Danish throne if the latter's male line died out, but renounced his rights to the throne in 1851 in favor of his aunt, Louise. Frederick William was of practically Danish upbringing, having lived all his life in Denmark, but in 1875, when the senior branch of Hesse-Kassel became extinct, he settled in northern Germany, where the House had substantial landholdings.
On 25 January 1893, Frederick Charles married Princess Margaret of Prussia, youngest sister of Kaiser Wilhelm II and a granddaughter of Queen Victoria of the United Kingdom. They had six children, all sons, including two sets of twins:
Upon their father's death in 1884, Frederick's eldest brother Frederick William became the head of the House of Hesse, and afterwards his next brother Alexander.
Later life[edit]
Landgrave Alexander Frederick of Hesse abdicated as the head of the House of Hesse on 16 March 1925, and was succeeded by Frederick Charles, his younger brother.
At Frederick's death, his eldest surviving son, Philipp, succeeded him as head.
However, according to certain family documents and correspondence, his successor as King of Finland would have been his second surviving son Prince Wolfgang of Hesse (1896–1989), apparently because Philipp was already the designated heir of the rights over the Electorate of Hesse, but certainly because Wolfgang was with his parents in 1918 and ready to travel to Finland, where a wedding to a Finnish lady was already in preparation for the coming crown prince. Philipp was in the military and unable to be contacted at the time. This choice of the younger of the twins, however, was not intended to mean that in future generations, the kingship would have been passed on through secundogeniture, with the eldest son always succeeding to the Hesse title (according to Dr. Vesa Vares). On the contrary, it is practically inconceivable that succession of a kingdom would depend on secondary consideration.
