The young Crown Prince Carl Gustaf was seven years old before he was told about his father's death, and he expressed his feelings about growing up without knowing his father in a speech in 2005.
He was christened at the Royal Chapel on 7 June 1946 by the Archbishop of Uppsala, Erling Eidem.
His godparents were the Crown Prince and Crown Princess of Denmark (his paternal uncle and aunt), the Crown Prince of Norway, Princess Juliana of the Netherlands, the King of Sweden (his patrilineal great-grandfather), the Hereditary Prince of Saxe-Coburg and Gotha (his maternal uncle), the Crown Prince and Crown Princess of Sweden (his paternal grandfather and stepgrandmother), and Count Folke and Countess Maria Bernadotte af Wisborg.
Prince Carl Gustaf was also given the title of the Duke of Jämtland.
His father, Prince Gustaf Adolf, Duke of Västerbotten, was killed in an airplane crash on 26 January 1947, at Copenhagen Airport.
Prince Carl Gustaf was the youngest of five children and the only son of Sweden's Prince Gustaf Adolf and Princess Sibylla.
His father's death had left the nine-month-old Prince second in line for the throne, behind his grandfather, then Crown Prince Gustaf Adolf.
When his great-grandfather Gustaf V died in 1950, the four-year-old Prince became the heir apparent of Sweden.
Carl XVI Gustaf (full name: Carl Gustaf Folke Hubertus, born 30 April 1946) is the current King of Sweden.
He ascended the throne upon the death of his grandfather, King Gustaf VI Adolf on 15 September 1973.
He is the only son of Prince Gustaf Adolf, Duke of Västerbotten, and Princess Sibylla of Saxe-Coburg and Gotha.
The King's heir apparent, upon passage on 1 January 1980 of a new law establishing absolute primogeniture (the first such law passed in European history), is Crown Princess Victoria, the eldest child of the King and his wife, Queen Silvia.
