Fernando II, King of Portugal

Dom Ferdinand II (German: Ferdinand August Franz Anton Koháry von Sachsen-Coburg-Gotha; 29 October 1816 – 15 December 1885), also known as Ferdinand of Saxe-Coburg and Gotha and as "the King-artist" (Portuguese: o Rei-Artista), was King of Portugal from 16 September 1837 to 15 November 1853 as the husband and co-ruler of Queen Maria II. In keeping with Portuguese law, Ferdinand only became king after the birth of his first son, Prince Pedro, in 1837. Ferdinand's reign came to an end with the death of his wife in 1853, but he served as regent for his son and successor, King Pedro V, until 1855. He retained the style and title of king even after the death of Maria II and her succession by their children Pedro V and then Luís I. His sons were reigning kings, while Ferdinand himself was a king-father during their reigns.
