Princess Leonor Queen of Spain
Princess Leonor of Spain, officially known as Leonor de Borbón y Ortiz, is the heir to the Spanish throne and the future Queen of Spain.
Born into the Spanish royal family, she has gradually taken on more public responsibilities as she prepares for her future constitutional role.
Although she is often searched for online as “Princess Leonor Queen of Spain,” she is currently the Princess of Asturias and heir presumptive to the Spanish Crown, not yet queen. Her father, King Felipe VI, remains the reigning monarch. Leonor was born in Madrid on October 31, 2005, and is the elder daughter of King Felipe VI and Queen Letizia.
BlogWho Is Princess Leonor of Spain?
Princess Leonor is the firstborn child of King Felipe VI and Queen Letizia. Following her father’s accession to the throne in June 2014, Leonor became the heir to the Spanish Crown and received the title Princess of Asturias.
Her official titles also include Princess of Girona and Princess of Viana, as well as Duchess of Montblanc, Countess of Cervera, and Lady of Balaguer. These titles reflect historical traditions connected with the territories and institutions that formed the Spanish monarchy. (Casa Real)
As the future monarch, Leonor’s education and public preparation have received considerable attention. Her development has included academic studies, constitutional responsibilities, public speaking, and extensive military training.
Princess Leonor’s Early Life and Family
Leonor was born in Madrid on October 31, 2005. She is the first daughter of Felipe VI and Letizia and has a younger sister, Infanta Sofía.
Her father became King of Spain in 2014 after the abdication of his father, King Juan Carlos I. With Felipe VI’s accession, Leonor became the direct heir to the Spanish throne. (Casa Real)
Growing up as the future head of state has meant that Leonor’s childhood and adolescence have included a level of public responsibility that is unusual compared with most young people. Her parents have emphasized education and preparation for her eventual institutional duties.
Education of Princess Leonor
Education has been an important part of Leonor’s preparation for the future. She completed her secondary education at UWC Atlantic College in Wales, where she studied the International Baccalaureate.
After finishing secondary school, her next stage involved combining higher education with an intensive military program. The Spanish Royal Household announced that her military preparation would span three academic years and involve the Army, Navy, and Air and Space Force. (Casa Real)
In April 2026, the Royal Household announced that Leonor would study Political Science at Universidad Carlos III de Madrid. The four-year degree covers areas including political science, law, economics, sociology, history, humanities, and international relations. (Casa Real)
Her university studies are intended to complement her practical preparation for a future constitutional role.
Princess Leonor’s Military Training
One of the most distinctive aspects of Princess Leonor’s preparation has been her military education.
Beginning in 2023, she started a three-year military training program designed to give her experience across Spain’s three armed services. The program began at the General Military Academy in Zaragoza before continuing through naval and air-force training. (Casa Real)
This preparation is particularly significant because the Spanish Constitution assigns the King or Queen important responsibilities as supreme commander of the Armed Forces.
During her training at the Academia General del Aire y del Espacio in San Javier, Leonor received aviation instruction and trained on the Pilatus PC-21 aircraft. In 2026, she also completed basic parachute training and achieved her first solo flight as part of her military education. (Casa Real)
The Royal Household has stated that in July 2027, Leonor is expected to receive the corresponding military commissions as lieutenant in the Army and Air and Space Force and as ensign in the Navy. (Casa Real)
Leonor’s Constitutional Role
Princess Leonor’s future position is not simply ceremonial. As Spain’s heir, she is being prepared to understand the country’s constitutional system and the responsibilities associated with the Crown.
A major milestone occurred on October 31, 2023, when Leonor swore allegiance to the Spanish Constitution before the Spanish Parliament on her 18th birthday. This was an important constitutional step in her development as heir to the throne. (Casa Real)
Her public appearances increasingly involve official ceremonies, national events, cultural occasions, and engagements connected with Spanish society.
Why Is Princess Leonor Important to Spain?
Leonor represents the next generation of Spain’s constitutional monarchy. Her eventual accession will mark a significant transition because she is being prepared to become Spain’s head of state after King Felipe VI.
Her preparation combines traditional royal duties with modern education. Rather than receiving only ceremonial training, she is developing knowledge in areas such as politics, international relations, law, economics, defense, and public service.
Her military experience is also designed to provide firsthand knowledge of the institutions she may eventually serve as commander in chief.
Princess Leonor as Future Queen of Spain
The phrase “Queen of Spain” refers to Leonor’s expected future position rather than her current status. She will become queen when she succeeds King Felipe VI according to Spain’s constitutional succession arrangements.
The timing of her accession cannot be predicted simply by age because it depends on when the current monarch’s reign ends. For now, Leonor’s principal responsibility is to continue preparing for the duties associated with being heir to the Crown.
Her upcoming university studies are another important stage in that preparation. The Royal Household has confirmed that she will combine her university education with institutional commitments as heir to the Crown. (Casa Real)
Princess Leonor’s Public Image
As a young member of the Spanish royal family, Leonor has attracted significant public interest both in Spain and internationally. Her speeches and official appearances have contributed to her growing visibility.
Her public role is gradually expanding as she participates in more national ceremonies and represents the Crown at selected events. This gradual transition allows her to gain experience while learning how Spain’s institutions and constitutional framework operate.
Her combination of academic preparation, military education, and public responsibilities makes her path toward the throne distinctive among contemporary European royal heirs.
What Does the Future Hold for Princess Leonor?
The coming years are expected to be an important period in Leonor’s development. Completing her military training, pursuing political science studies, and continuing her institutional responsibilities will give her experience across several areas relevant to future state leadership.
Her education is particularly significant because a modern monarch must understand not only royal traditions but also democratic institutions, international relations, economics, law, and the constitutional limits of the Crown.
As she takes on additional responsibilities, the Spanish public will likely see more of Leonor in official settings and international engagements.

Princess Leonor of Spain is preparing for one of the most important constitutional roles in the country. Born in Madrid in 2005, she became heir to the Spanish Crown after her father became King Felipe VI in 2014.
Her journey toward becoming Queen of Spain includes an unusual combination of academic achievement, constitutional preparation, military service, and public duties. Her three-year military education and planned Political Science degree demonstrate the comprehensive preparation being undertaken for her future responsibilities. (Casa Real)
While Leonor is not yet Queen of Spain, she is the current Princess of Asturias and heir to the throne. Her continuing education and increasing public role are shaping the future of Spain’s monarchy and making her one of Europe’s most closely watched young royal figures.
