On 20 October 1905, King Alfonso XIII announced the marriage between his elder sister Infanta María Teresa and Prince Ferdinand Maria. The announcement was gazetted in the Gazette of Madrid as follows: "For the sake of My Royal Family and of the Nation, after having heard My Council of Ministers, I shall give My Royal Consent to the contract of marriage between My Most Beloved and Most Dear Sister Infanta María Teresa and My Most Beloved Cousin Prince Ferdinand Maria of Bavaria and Bourbon. My Government will inform the Cortes this My Royal Resolution". That same day, Prince Ferdinand Maria naturalised and the king granted unto him the title and prerogative of Infante of Spain, by grace. He was also invested a Knight of the Order of the Golden Fleece and was granted the Collar and Grand Cross of the orders of Charles III and Isabella the Catholic, respectively.
