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.

Queen Letizia and her daughter, Infanta Elena, were in Australia to celebrate Spain’s victory over England in the Women’s World Cup.

Her Majesty was seen nervous as the game wound to a close and then embraced team members as they basked in victory.

The Queen’s trip came as the Royal Family retakes its agenda after summer vacations. Princess Leonor did not attend. She entered military training in recent days.

Media outlets contrasted the Queen’s trip with British royals staying home during the game. News reports said they cited environmental reasons.

Members of the Spanish Royal Family arrived in the island of Mallorca in recent days for the beginning of their summer vacation.

King, Felipe, Queen Letizia, Princess Leonor and Infanta Sofia visited historic gardens Monday. They usually make a point of seeing at least one notable place on the island every year.

King Felipe also held meetings with Balearic Island leaders at the Almudaina Palace in downtown Palma de Mallorca. The family stays at a different palace, Marivent, when vacationing.

Queen Sofia is the biggest fan of vacationing in Mallorca and Marivent Palace. She’s seen there during the summer and Easter.

However, her last public event was Monday with members of the Belgian Royal Family to attend ceremonies in memory of the late King Baudouin, who died in Spain in the 1990s.

Separately last week, King Felipe and Queen Letizia attended the opening of the Gallery of Royal Collections in Madrid.

Europe’s constitutional kings and queens are mostly figureheads. “Mostly” is an important word there. Contrary to popular belief, they do have certain powers.

In Spain and in other nations, the monarch plays a role who ends up governing. King Felipe’s role is particularly pivotal.

Now that Spanish voters delivered an inconclusive result, His Majesty will be meeting with whoever is chosen to president over the Chamber of Deputies. He will also meet with all party leaders.

Once those consultations are over, King Felipe will task one of the party leaders with forming a government based on the likelihood of success.

If one leader fails, the king may choose someone else to give it a go. A continued impasse could mean new elections.

But if there is success, King Felipe will take the new prime minister’s oath and that of his ministers. They must all swear allegiance to him and the constitution.
