Carol II (15 October 1893 –4 April 1953) reigned as King of Romania from 8 June 1930 until 6 September 1940. He was the first of the Hohenzollern kings of Romania to be born in the country (both of his predecessors were born and grew up in Germany and only came to Romania as adults). Carol, by contrast, spoke Romanian as his first language and was the first member of the Romanian royal family to be raised in the Orthodox faith. He possessed a hedonistic personality that contributed to the controversies and misrule that marred his reign. In 1940, he was forced to abdicate and withdraw into foreign exile.
