About Edward I of Portugal

Lived 1391 – 1438 (aged 46). Edward I of Portugal was a king and writer.

Edward ( ; 31 October 1391 – 9 September 1438), also called Edward the Philosopher King (Duarte o Rei-Filósofo) or the Eloquent (o Eloquente), was the King of Portugal from 1433 until his death. He was born in Viseu, the son of John I of Portugal and Philippa of Lancaster. Edward was the oldest member of the "Illustrious Generation" of royal children who contributed to the political, social and economic development of Portuguese society during the 15th century.

Early life Edward was the second born male legitimate son of King John I. He became the heir to the throne after his brother Afonso died in 1400, aged 10.

Before he ascended to the throne, Edward always followed his father in the affairs of the kingdom. He was knighted in 1415 after the Portuguese capture of the city of Ceuta in North Africa, across from Gibraltar. He became king in 1433, when his father died of the plague.

As king, Edward soon showed interest in building internal political consensus. During his short reign of five years, he called the Portuguese Cortes (the national assembly) no less than five times to discuss the political affairs of his kingdom. He also followed the politics of his father concerning the maritime exploration of Africa. He encouraged and financed his famous brother, Henry the Navigator, who initiated many expeditions on the west coast of Africa. An expedition of Gil Eanes in 1434 first rounded Cape Bojador on the northwestern coast of Africa, leading the way for further exploration southward along the African coast.

Colonial affairs

The colony at Ceuta rapidly became a drain on the Portuguese treasury, and it was realised that without the city of Tangier, possession of Ceuta was worthless. After Ceuta was captured by the Portuguese, the camel caravans that were part of the overland trade routes began to use Tangier as their new destination. This deprived Ceuta of the materials and goods that made it an attractive market and a vibrant trading locale, and it became an isolated community.

In 1437, Edward's brothers Henry and Ferdinand persuaded him to launch an attack on the Marinid sultanate of Morocco. The expedition was not unanimously supported and was undertaken against the advice of the Pope. 5= 5. Teresa Lourenço 7= 7. Blanche of Lancaster 9= 9. Beatrice of Castile 11= 11.
