Christian IX died on 29 January 1906, and Frederik's grandfather Crown Prince Frederik succeeded him as King Frederik VIII. Frederik's father became crown prince, and Frederik moved up to second in line to the throne.{{citation needed|date=August 2022}}

Just six years later, on 14 May 1912, King Frederik VIII died, and Frederik's father ascended the throne as King Christian X. Frederik himself became crown prince. On 1 December 1918, as the [[Danish–Icelandic Act of Union]] recognized Iceland as a fully [[sovereign state]] in [[personal union]] with Denmark through a common [[monarch]], Frederik also became crown prince of [[Kingdom of Iceland|Iceland]] (where his name was officially spelled Friðrik). However, as a [[1944 Icelandic constitutional referendum|national referendum]] [[Founding of the Republic of Iceland|established the Republic of Iceland]] on 17 June 1944, he never succeeded as king of Iceland.{{citation needed|date=August 2022}}

Frederik was educated at the [[Royal Danish Naval Academy]] (breaking with Danish royal tradition by choosing a naval instead of an army career) and the [[University of Copenhagen]]. Before he became king, he had acquired the rank of [[rear admiral]] and he had had several senior commands on active service. He acquired several tattoos during his naval service including dragons, birds, and other [[American traditional|traditional tattoo]] motifs that were popular among sailors of the time.<ref>{{Cite web |last=Barrett |first=Michael |date=6 Jan 2020 |title=The Danish king who was heavily tattooed – and how his ink was recreated |url=https://www.thelocal.dk/20200106/the-danish-king-who-was-heavily-tattooed-and-how-researchers-recreated-his-ink |access-date=19 October 2024 |website=The Local Denmark}}</ref>

In addition, with his great love of music, Frederik was an able [[piano]] player and [[Conducting|conductor]].<ref>{{cite web | url=https://www.dacapo-records.dk/en/artists/king-frederik-ix | title=Frederik IX | date=15 March 2016 | access-date=3 June 2023 | archive-date=3 June 2023 | archive-url=https://web.archive.org/web/20230603064739/https://www.dacapo-records.dk/en/artists/king-frederik-ix | url-status=live }}</ref>
