A few days later, he renounced his place in the line of succession to the Danish throne, forfeiting the title "Prince of Denmark" and the style of Royal Highness (the latter having only been granted to him and his brothers by the king on 5 February 1904). With the king's authorisation, he assumed the title "Prince Aage, Greve af (Count of) Rosenborg" and the style of Highness on 5 February 1914. use of the princely prefix was restricted to himself and his wife alone.
