He was the eldest son of Christian August, Duke of Schleswig-Holstein-Sonderburg-Augustenburg (1696–1754) and his wife Duchess Louise Frederikke née Countess af Danneskiold-Samsøe (1699–1744). In 1754, his father died and Frederick Christian inherited Augustenborg Castle and Gråsten. However, these estates were deeply in debt. He waived his claims on the duchies of Schleswig and Holstein and in return the King of Denmark (who was also Duke of Schleswig and Holstein) granted him a favourable settlement. This allowed him to purchase Als and Sundeved, making him the largest landowner in Schleswig. He was also able to expand Augustenborg Castle, the family residence.

Frederick Christian served as a general in the Danish army. He was a Knight of the Order of the Elephant.

Marriage and issueEdit

On 26 May 1762, Frederick Christian married Princess Charlotte Amalie Wilhelmine (1744–1770), a daughter of Frederick Charles, Duke of Schleswig-Holstein-Sonderburg-Plön. The couple had seven children:

  • Louise Christine Caroline (16 February 1763 – 27 January 1764);
  • Louise Christine Caroline (17 February 1764 – 2 August 1815);
  • Frederick Christian II (28 September 1765 – 14 June 1814), married Princess Louise Auguste of Denmark;
  • Frederick Charles Emil (8 March 1767 – 14 June 1841), Danish General, married Sofie Eleonore Fredericka of Scheel (1776–1836; daughter of Baron Jürgen Eric of Scheel);
