The Spanish princess, Leonor de Borbón, swears allegiance to the Spanish Constitution

The Princess of Asturias, Leonor de Borbón, swore her allegiance to the Spanish Constitution as heir to the throne of Spain upon reaching the age of majority, as established by Spanish law. The heir to the Head of State took the oath in a solemn ceremony in the Spanish Congress of Deputies and then received the medals from the Congress and the Senate.

"Today the Princess of Asturias has sworn allegiance to the Spanish Constitution before the Cortes Generales on the occasion of her coming of age," the Royal Family announced on its X account (formerly Twitter) in a message that was accompanied by photographs of the event.

Her father took the same oath when he was prince, on January 30, 1986, when he came of age. The tradition is made in compliance of article 61.2 of the Constitution. "The Crown Prince, upon reaching the age of majority, and the Regent or Regents upon taking charge of their duties, must take the same oath, as well as that of fidelity to the King," the law says.

Leonor's 18th birthday

On the occasion of Leonor's birthday, a reception was also held at the Royal Palace in Madrid, where the collar of the Royal and Distinguished Spanish Order of Charles III will be placed on the Princess of Asturias in the presence of the powers of the State. Then there will be a family reunion at the El Pardo Palace, on the outskirts of Madrid.

The celebration takes place only weeks after the princess pledged her life in the service of the Spain. On Saturday, October 7, the heiress assured, in her flag oath, that she will defend Spain. It was the most important act so far of her military training.

Leonor is the current Princess of Asturias and first in the line of succession to the Spanish throne, as the first-born of King Felipe VI and Queen Letizia. The princess was born during the reign of her grandfather, King Emeritus Juan Carlos I.

The Spanish princess did her primary and secondary studies at the Colegio de Santa María de los Rosales in Madrid, the same school where her father was educated. After completing secondary education, she completed an international baccalaureate at the UWC Atlantic College in Wales (United Kingdom). In August of this year, the heir to the throne began her military training at the General Military Academy of Zaragoza.
