Another period for the title began at the beginning of the 19th century with the arrival of the constitutional regime. For Agustín Argüelles, an Asturian deputy in the Cortes of Cádiz, the draft of the Constitution of 1812 preserved more by "custom than by utility or precision" the title of Prince of Asturias to the heir of the Crown. The commission responsible for the writing of the new constitution, equating the Crown Prince with the Prince of Asturias, proposed that the Cortes should recognize him immediately after announcing his birth and that upon reaching the age of 14, the prince should swear before the Cortes the defence of the Catholic faith, the preservation of the Constitution, and obedience to the King. During discussions, some deputies proposed that the Prince should be renamed "of the Spains" and not "of Asturias", while others wanted him to use the dignity only after his oath and not from his birth. Besides Argüelles, the Asturians Pedro Inguanzo Rivero and Alonso Cañedo Vigil, each with opposing ideologies, defended, respectively, a title of honor or a title that was purely nominal, without royal rights but consecrated by history. The project remained unchanged and was finally approved.
