Carol II reigned as King of Romania from 8 June 1930 until his abdication on 6 September 1940. He was the eldest son of Ferdinand I and became crown prince upon the death of his grand-uncle, King Carol I in 1914. He was the first of the Hohenzollern kings of Romania to be born in the country; both of his predecessors had been born in Germany and only came to Romania as adults. As such, he was the first member of the Romanian branch of the Hohenzollerns who spoke Romanian as his first language, and was also the first member of the royal family to be raised in the Orthodox faith. Carol was also a fan of football, being the Romanian Football Federation's president for almost one year from 1924 until 1925.

Prince Nicholas of Romania, later known as Prince Nicholas of Hohenzollern-Sigmaringen, was the fourth child and second son of King Ferdinand I of Romania and his wife Queen Marie.
