Later Life

In 1387, Philippa married King John I of Portugal and became the first English woman to be crowned as the Queen consort of Portugal. This marriage served as a major agreement in procuring the Anglo-Portuguese Alliance against the France-Castile axis.

On February 2, 1387, the royal couple was blessed by the church in the Cathedral of Porto. Twelve days later, the wedding ceremony took place on February 14, 1387, a union which the Portuguese court celebrated for fifteen days.

By marrying Philippa, John I established a political and personal alliance with her father, the John of Gaunt, who in 1386 had signed the Portuguese-British Alliance, which continued through the Napoleonic Wars and ensured Portugal's tenuous neutrality in World War II.

King John I already had a mistress, Inês Peres Esteves, with whom who he had three children: Afonso, Beatrice and Branca. Philippa commanded her to leave the court and moved her to a convent where Esteves became a Prioress. However, she allowed Afonso and Beatrice to be raised in the Portuguese court.

Philippa had nine children with King John I, of who three died in infancy. Her eldest surviving child was Edward, born in 1391, who grew up to become a writer and succeeded his father as King of Portugal in 1433.

Her second surviving son, Peter, was born in 1392, who later became the Duke of Coimbra. In 1394, Henry was born, who famously became known as "the Navigator", the first Duke of Viseu, who guided Portugal to the Age of Discovery.

Philippa’s first surviving daughter, Isabella, was born in 1397 and later married Philip III of Burgundy. Her last two sons with the king, John and Ferdinand, were born in 1400 and 1402, respectively.

Major Works

Philippa wielded enormous influence in both the Portuguese and English courts and was actively involved in political affairs. She often wrote to the English court from Portugal and stayed involved in English politics. She was also able to improve the diplomatic and commercial bonds between the two kingdoms.

Her political contribution to her own court was immense. Because of the Portuguese involvement in several wars, the Portuguese economy was deteriorating. Therefore, she arranged to send an expedition for the conquest and control of Ceuta which proved to be quite lucrative for Portugal as it gained the control of the African and Indian spice trade.

Personal Life & Legacy

At the age of 53, she contracted plague and was moved from Lisbon to Sacavém. She called her sons to her bedside so that she could give them her blessing.

Philippa died peacefully on July 19, 1415, in Sacavém, Portugal, at the age of 55, and was buried in the Batalha Monastery, Leiria, Portugal. She was said to be lucid and without pain during the final hours of her life.
