Leonor, the Princess of Asturias and heir to the Spanish throne, turned 18 today and took an oath to the Constitution during a ceremony before parliamentarians in Madrid.

The princess, who is currently going through military training, has for years been preparing for a public role in support of the Crown. The oath was one of the most important steps in the process.

King Felipe, Queen Letizia and Infanta Sofia accompanies the princess to the Congress of the Deputies and later to a reception at the Madrid Royal Palace.

There the King granted her the Collar of Charles III. He made his daughter a member of the Order of the Golden Fleece when she turned 10.

King Juan Carlos and Queen Sofia did not attend the official ceremonies. They were scheduled to attend a family reception at the Royal Palace of El Pardo.

Actress Meryl Street was the most high-profile winner at the Princess of Asturias Awards this year.

The Princess of Asturias Foundation held the ceremony in Oviedo in the Principality of Asturias earlier this month. It’s the most high-profile award given by the Spanish Royal Family.

In attendance at the Campoamor Theater were King Felipe, Queen Letizia, Queen Sofia, Princess Leonor and Infanta Sofia. Princess Leonor holds the Asturias title as heir to the Spanish throne.

Princess Leonor handed out the certificates herself. She is preparing to take an oath to Parliament upon turning 18.

Other winners included: Haruki Murakami in letters, Eliud Kipchoge in sport and Mary’s Meals in concord, among others.

Events related to the Princess of Asturias Awards last three days. There’s a concert the day before the awards presentation and a visit to an Asturian community the day after.

Leonor, the Princess of Asturias, played a central role in last week’s military parade in Madrid to commemorate Spanish National Day.

Members of the Royal Family usually preside over the display through one of Madrid’s main avenues, plus a jet flyover, followed by a reception at the Royal Palace.

Princess Leonor, who is currently undergoing military training as heir to the throne, took a more prominent role in the ceremonies this year.

The Fiesta Nacional coincides with the anniversary of Christopher Columbus’ first arrival in the Americas. Countries around the world celebrate Hispanic heritage around the same time.

Princess Leonor, heir to the Spanish throne, swore allegiance to the flag during a ceremony at the Zaragoza Military Academy this weekend.

King Felipe and Queen Letizia were on hand to witness the occasion. It’s all part of the princess’ preparation to become head of state.

Princess Leonor is scheduled to take an oath as heir before Spanish lawmakers later this month.

King Felipe and Queen Letizia met last week with Ukranian President Volodymyr Zelensky, who attended a meeting of European leaders.

Their Majesties hosted Zelensky and other leaders at the Alhambra Palace in Granada. Russia was not invited to the summit.

King Felipe this weekend condemned militant attacks against Israel Saturday, in a move that has escalated into a broader Middle East conflict.

His Majesty, during remarks in Bilbao, said he repudiated the attacks “with all firmness,” called on the return of hostages and for the end of human suffering in the region.

One of the titles that has been historically associated with the Spanish Crown is that of king of Jerusalem. It’s a title that dates back to the crusades.

Leonor, the Princess of Asturias, will take an oath to the Constitution in October as heir to the Spanish throne.

The princess, who will turn 18 on October 31, is beginning several years of military training as part of her preparation to become monarch.

The Spanish Royal Household in recent days released images of Her Royal Highness at the Zaragoza Military Academy.

Princess Leonor’s father, King Felipe, took the oath before lawmakers in 1986. The ceremony also happened upon his turning 18.

The Spanish Cortes Generales — the Congress and Senate — are preparing for Princess Leonor’s oath as lawmakers struggle to form a government after inconclusive elections.

King Juan Carlos, Princess Leonor’s grandfather, will not be at the official ceremonies, including a reception at the Madrid Royal Palace, but will attend a family gathering at the Royal Palace of El Pardo.

King Felipe and Queen Letizia were quick to express their condolences last weekend following the deadly earthquake in Morocco.

King Felipe, on behalf of himself and his wife, penned a letter to Moroccan King Mohammed. The missive referred to the Moroccan ruler as “brother.”

Spain was one of the few countries initially allowed to send aid workers to the earthquake zone. However, the countries are often at odds.

Morocco, for example, still claims the Spanish cities of Melilla and Ceuta in North Africa. Immigration is another sensitive issue.

Infanta Sofía, King Felipe and Queen Letizia’s youngest daughter, has left for school in Wales.

Her Royal Highness, 16, is attending UWC Atlantic. Her sister, Princess Leonor, recently graduated from the school.

Princess Leonor entered military training after leaving UWC Atlantic as part of her preparation to eventually become queen.

King Felipe this month tapped Alberto Núñez Feijóo, the head of the center-right Popular Party, to form a government after Spain’s recent inconclusive elections.

His Majesty met with party leaders before announcing his decision. The Royal Household said it was because Feijóo’s party received the most seats.

If Feijóo fails to form a government, King Felipe will likely ask Acting Prime Minister Pedro Sánchez to make an attempt at remaining in power. If that doesn’t work, there would likely be new elections.

Sánchez’s Socialists won a partial victory when their candidate to moderate parliamentary debates won. It happened after the party promised nationalist parties to allow languages other than Castilian during sessions.

The Popular Party was hoping far right Vox would support its candidate to lead parliamentary debates, but Vox stuck with its own pick.
