John I (Portuguese : João [ʒuˈɐ̃w̃]; 11 April 1357 – 14 August 1433), also called John of Aviz, was King of Portugal from 1385 until his death in 1433. He is recognized chiefly for his role in Portugal's victory in a succession war with Castile, preserving his country's independence and establishing the Aviz (or Joanine) dynasty on the Portuguese throne. His long reign of 48 years, the most extensive of all Portuguese monarchs, saw the beginning of Portugal's overseas expansion. John's well-remembered reign in his country earned him the epithet of Fond Memory (de Boa Memória); he was also referred to as "the Good" (o Bom), sometimes "the Great" (o Grande), and more rarely, especially in Spain, as "the Bastard" (Bastardo).
As part of his efforts to acquire Portuguese territories in Africa, he became the first king of Portugal to use the title "Lord of Ceuta".
John was born in Lisbon as the natural son of King Peter I of Portugal by a woman named Teresa, who, according to the royal chronicler Fernão Lopes, was a noble Galician. In the 18th century, António Caetano de Sousa found a 16th-century document in the archives of the Torre do Tombo in which she was named as Teresa Lourenço. In 1364, by request of Nuno Freire de Andrade, a Galician Grand Master of the Order of Christ, he was created Grand Master of the Order of Aviz.
On the death without a male heir of his half-brother, King Ferdinand I, in October 1383, strenuous efforts were made to secure the succession for Beatrice, Ferdinand's only daughter. As heir presumptive, Beatrice had married king John I of Castile, but popular sentiment was against an arrangement in which Portugal would have been virtually annexed by Castile. The 1383–1385 Portuguese interregnum followed, a period of political anarchy, when no monarch ruled the country.
On 6 April 1385, the Council of the Kingdom (the Portuguese Cortes) met in Coimbra and declared John, then Master of Aviz, to be king of Portugal.This was followed by the liberation of almost all of the Minho in the course of two months as part of a war against Castile in opposition to its claims to the Portuguese throne. Soon after, the king of Castile again invaded Portugal with the purpose of conquering Lisbon and removing John I from the throne. John I of Castile was accompanied by French allied cavalry while English troops and generals took the side of John of Aviz (see Hundred Years' War). John and Nuno Álvares Pereira, his constable and talented supporter, repelled the attack in the decisive Battle of Aljubarrota on 14 August 1385. John I of Castile then retreated. The Castilian forces abandoned Santarém, Torres Vedras and Torres Novas, and many other towns were delivered to John I by Portuguese nobles from the Castilian side. As a result, the stability of the Portuguese throne was permanently secured.
On 14 February 1387, John I married Philippa of Lancaster, daughter of John of Gaunt,who had proved to be a worthy ally. The marriage consolidated an Anglo-Portuguese Alliance that endures to the present day.
John I of Castile died in 1390 without issue from his wife Beatrice, which meant that a competing legitimate bloodline with a claim to the throne of Portugal died out. John I of Portugal was then able to rule in peace and concentrate on the economic development and territorial expansion of his realm. The most significant military actions were the siege and conquest of the city of Ceuta by Portugal in 1415, and the successful defence of Ceuta from a Moroccan counterattack in 1419. These measure were intended to help seize control of navigation off the African coast and trade routes from the interior of Africa.
The raids and attacks of the Reconquista in the Iberian Peninsula created captives on both sides who were either ransomed or sold as slaves. The Portuguese crown extended this practice to North Africa. After the attack on Ceuta, the king sought papal recognition of the military action as a Crusade. Such a ruling would have enabled those captured to be legitimately sold as slaves.In response to John's request, Pope Martin V issued the Papal bull Sane charissimus of 4 April 1418, which confirmed to the king all of the lands he might win from the Moors. Under the auspices of Prince Henry the Navigator, voyages were organized to explore the African coast. These led to the discovery of the uninhabited islands of Madeira in 1417 and the Azores in 1427; all were claimed by the Portuguese crown.
Contemporaneous writers describe John as a man of wit who was very keen on concentrating power on himself, but at the same time possessed a benevolent and kind demeanor. His youthful education as master of a religious order made him an unusually learned king for the Middle Ages. His love for knowledge and culture was passed on to his sons, who are often referred to collectively by Portuguese historians as the "illustrious generation" (Ínclita Geração): Edward, the future king, was a poet and a writer; Peter, the Duke of Coimbra, was one of the most learned princes of his time; and Prince Henry the Navigator, the duke of Viseu, invested heavily in science and the development of nautical pursuits. In 1430, John's only surviving daughter, Isabella, married Philip the Good, Duke of Burgundy, and enjoyed an extremely refined court culture in his lands; she was the mother of Charles the Bold.
On 2 February 1387, John I married Philippa of Lancaster, daughter of John of Gaunt, 1st Duke of Lancaster, in Porto. From that marriage were born several famous princes and princesses of Portugal (infantes) that became known as the "illustrious generation".

Afonso V, known by the sobriquet the African, was King of Portugal. His sobriquet refers to his conquests in Northern Africa.
D. Nuno Álvares Pereira, O. Carm., also spelled Nun'Álvares Pereira, 7th Count of Barcelos, 3rd Count of Ourém and 2nd Count of Arraiolos, was a Portuguese general of great success who had a decisive role in the 1383-1385 Crisis that assured Portugal's independence from Castile. He later became a mystic and was later beatified by Pope Benedict XV, in 1918, and canonised by Pope Benedict XVI in 2009.
John I was king of the Crown of Castile from 1379 until 1390. He was the son of Henry II and of his wife Juana Manuel of Castile. He was the last monarch of Castile to receive a formal coronation.
Ferdinand I, sometimes called the Handsome or occasionally the Inconstant, was the King of Portugal from 1367 until his death in 1383. His death led to the 1383–85 crisis, also known as the Portuguese interregnum.
Duarte, known in English as Edward and called the Philosopher or the Eloquent, was King of Portugal from 1433 until his death. He was born in Viseu, the son of John I of Portugal and his wife, Philippa of Lancaster. Edward was the oldest member of the "Illustrious Generation" of accomplished royal children who contributed to the development of Portuguese civilization during the 15th century. As a cousin of several English kings, he became a Knight of the Garter.
Beatrice was the only surviving legitimate child of King Ferdinand I of Portugal and his wife, Leonor Teles. She became Queen consort of Castile by marriage to King John I of Castile. Following her father's death without a legitimate male heir, she claimed the Portuguese throne, but lost her claim to her uncle, who became King John I of Portugal, founder of the House of Aviz.
The Battle of Aljubarrota was a battle fought between the Kingdom of Portugal and the Crown of Castile on 14 August 1385. Forces commanded by King John I of Portugal and his general Nuno Álvares Pereira, with the support of English allies, opposed the army of King John I of Castile with its Aragonese, Italian and French allies at São Jorge, between the towns of Leiria and Alcobaça, in central Portugal. The result was a decisive victory for the Portuguese, ruling out Castilian ambitions to the Portuguese throne, ending the 1383–85 Crisis and assuring John as King of Portugal.
The Battle of Alfarrobeira took place on 20 May 1449. It was a confrontation between the forces commanded by King Afonso V of Portugal and his uncle Afonso, Duke of Braganza, against the army of the rebellious Peter, Duke of Coimbra. The place was Vialonga, near Lisbon, at the margins of the creek of Alfarrobeira. The result was the clear defeat and death of the Duke of Coimbra and the establishment of the Braganzas as the most powerful House of Portugal.
Inês de Castro was a Galician noblewoman best known as lover and posthumously-recognized wife of King Peter I of Portugal. The dramatic circumstances of her relationship with Peter, which was forbidden by his father King Afonso IV, her murder at the orders of Afonso, Peter's bloody revenge on her killers, and the legend of the coronation of her exhumed corpse by Peter, have made Inês de Castro a frequent subject of art, music, and drama through the ages.
The 1383–1385 Portuguese interregnum was a time of civil war in Portuguese history when no crowned king reigned. It began when King Ferdinand I died without a male heir, and ended when King John I was crowned in 1385 after his victory in the Battle of Aljubarrota. Portuguese interpret this era as their earliest national resistance movement countering Castilian intervention; Robert Durand considers it the "great revealer of national consciousness." Bourgeoisie and nobility worked together to establish the Aviz dynasty securely on an independent throne, unlike the lengthy civil wars in France known as the Hundred Years' War, and England as the War of the Roses, where aristocratic factions fought powerfully against a centralised monarchy.
The House of Aviz, also known as the Joanine Dynasty, was a dynasty of Portuguese origin which flourished during the Renaissance and the period of the Portuguese discoveries, when Portugal expanded its power globally.
John of Portugal, occasionally surnamed Castro, was the eldest surviving son of King Peter I of Portugal by his mistress Inês de Castro. He was a potential but unsuccessful contender for the Portuguese throne during the 1383–85 crisis of succession.
Infante D. Pedro, Duke of CoimbraKG, was a Portuguese infante (prince) of the House of Aviz, son of King John I of Portugal and his wife Philippa of Lancaster, daughter of John of Gaunt. In Portugal, he is better known as Infante D. Pedro das Sete Partidas [do Mundo], "of the Seven Parts [of the World]" because of his travels. Possibly the best-travelled prince of his time, he was regent between 1439 and 1448. He was also 1st Lord of Montemor-o-Velho, Aveiro, Tentúgal, Cernache, Pereira, Condeixa and Lousã.
Infante John, Constable of Portugal was a Portuguese infante (prince) of the House of Aviz, Constable of Portugal and master of the Portuguese Order of St. James (Santiago). In Portugal, he is commonly referred to as the O Infante Condestável.
Infante Ferdinand, Duke of Viseu and Beja was the third son of Edward, King of Portugal and his wife Eleanor of Aragon.
Isabella of Urgell, Duchess of Coimbra was a Catalan noblewoman of the Urgell branch of the House of Aragon. She was the wife of Infante Peter, Duke of Coimbra.
The Fernandine Wars were a series of three conflicts between the Kingdom of Portugal under King Ferdinand I and the Crown of Castile under King Henry II. They were fought over Ferdinand's claim to the Castilian succession after the death of King Peter of Castile in 1369.
The Third Fernandine War was the last conflict of the Fernandine Wars, and took place between 1381–1382, between the Crown of Castile and the Kingdoms of Portugal and England. When Henry II of Castile died in 1379, John of Gaunt, 1st Duke of Lancaster claimed their rights of the throne of the Kingdom of Castile, and again found an ally in Ferdinand I of Portugal.
The Portuguese House of Burgundy or the Afonsine Dynasty was a Portuguese dynasty that ruled the Kingdom of Portugal from its founding until the 1383-85 Portuguese Interregnum.
The kingdom of Portugal was established from the county of Portugal in the 1130s, ruled by the Portuguese House of Burgundy. During most of the 12th and 13th centuries, its history is chiefly that of the gradual reconquest of territory from the various Muslim principalities (taifas) of the period.
