Frederick Henry, Electoral Prince of the Palatinate, ({{langx|de|Heinrich Friedrich}}; 1 January 1614 – 7 January 1629) was the eldest son of Frederick V, Elector Palatine and so-called "Winter King" of Bohemia, and his wife, Elizabeth Stuart, daughter of King James VI of Scotland and I of England.

Celebration of his birth

As soon as the prince was born, Elizabeth ordered "pieces" using the English word, meaning the firing of cannon to celebrate the birth.HMC Downshire, vol. 4 (London, 1940), p. 283.

He was named after his father and his late uncle Henry, Prince of Wales, who had died less than two years earlier during the celebrations leading up to his parents' wedding.{{Cite book |last=Goldstone |first=Nancy |url=https://www.worldcat.org/oclc/1029552788 |title=Daughters of the Winter Queen : four remarkable sisters, the crown of Bohemia, and the enduring legacy of Mary, Queen of Scots |date=2018 |isbn=978-0-316-38791-0 |edition=First |location=New York, NY |pages=56 |oclc=1029552788}}{{Cite book |last=Akkerman |first=Nadine |url=https://www.worldcat.org/oclc/1285494517 |title=Elizabeth Stuart, queen of hearts |date=2021 |isbn=978-0-19-164528-0 |location=Oxford |pages=64 |oclc=1285494517}} As a gift to celebrate Frederick Henry's birth, King James rewarded Elizabeth with a pension of 12,000 crowns a year for life and money and gold worth an additional 25,000 crowns.{{Cite book |last=Akkerman |first=Nadine |url=https://www.worldcat.org/oclc/1285494517 |title=Elizabeth Stuart, queen of hearts |date=2021 |isbn=978-0-19-164528-0 |location=Oxford |pages=103 |oclc=1285494517}}

Successor to the throne of Bohemia

In 1618, Frederick was elected King of Bohemia. Frederick Henry was the only one of his siblings to accompany his parents to Prague for the coronation and was elected successor to the Crown a few days before the birth of his brother Rupert.{{Cite book |last=Akkerman |first=Nadine |url=https://www.worldcat.org/oclc/1285494517 |title=Elizabeth Stuart, queen of hearts |date=2021 |isbn=978-0-19-164528-0 |location=Oxford |pages=136–7 |oclc=1285494517}} In September 1620, he was sent on a royal progress through Bohemia and the Upper Palatinate with a guard of 4,000 men, which ended in Leeuwarden where his kinsman Ernst Casimir, Stadtholder of Friesland, Groningen and Drenthe, took custody of him.{{Cite book |last=Akkerman |first=Nadine |url=https://www.worldcat.org/oclc/1285494517 |title=Elizabeth Stuart, queen of hearts |date=2021 |isbn=978-0-19-164528-0 |location=Oxford |pages=142–3 |oclc=1285494517}}

Exile in the Hague

After his parents lost control of Bohemia and the Palatinate, they fled to exile in the Hague. Frederick Henry joined them by May 1621, when he wrote a letter from the Hague to King James.HMC 3rd Report, Rev Hopkinson (London, 1872), p. 265. In June 1623, his parents set up a separate royal court for their children at a building three hours away in Leiden, known as the Prinsenhof or the Princes' court. Frederick Henry also formally enrolled as a student at Leiden University.{{Cite book |last=Akkerman |first=Nadine |url=https://www.worldcat.org/oclc/1285494517 |title=Elizabeth Stuart, queen of hearts |date=2021 |isbn=978-0-19-164528-0 |location=Oxford |pages=188–9 |oclc=1285494517}}{{Cite book |last=Goldstone |first=Nancy |url=https://www.worldcat.org/oclc/1029552788 |title=Daughters of the Winter Queen : four remarkable sisters, the crown of Bohemia, and the enduring legacy of Mary, Queen of Scots |date=2018 |isbn=978-0-316-38791-0 |edition=First |location=New York, NY |pages=113 |oclc=1029552788}}

Marriage negotiations

As part of various efforts to fight or negotiate an end to the Thirty Years War, several potential marriages were considered for Frederick Henry. These include marriages to a daughter of Holy Roman Emperor Ferdinand II and a niece of Maximilian I, Duke of Bavaria.{{Cite book |last=Akkerman |first=Nadine |url=https://www.worldcat.org/oclc/1285494517 |title=Elizabeth Stuart, queen of hearts |date=2021 |isbn=978-0-19-164528-0 |location=Oxford |pages=184–5, 199–202 |oclc=1285494517}}

Drowning

In 1629, Frederick Henry went with his father to Amsterdam to see the captured Spanish treasure fleet. While crossing Haarlemmermeer, their boat was struck by a barge and capsized. Frederick was rescued but Frederick Henry drowned and his body was not found until the next day.{{Cite book |last=Goldstone |first=Nancy |url=https://www.worldcat.org/oclc/1029552788 |title=Daughters of the Winter Queen : four remarkable sisters, the crown of Bohemia, and the enduring legacy of Mary, Queen of Scots |date=2018 |isbn=978-0-316-38791-0 |edition=First |location=New York, NY |pages=119 |oclc=1029552788}} He was buried in the Kloosterkerk, in the Hague.{{Cite book |last=Akkerman |first=Nadine |url=https://www.worldcat.org/oclc/1285494517 |title=Elizabeth Stuart, queen of hearts |date=2021 |isbn=978-0-19-164528-0 |location=Oxford |pages=252–3 |oclc=1285494517}}
