John of Foix, Viscount of Narbonne
John of Foix( 1450 – 1500, Étampes, France) was a younger son of Count Gaston IV of Foix and Queen Eleanor of Navarre.
His elder brother was Gaston, Prince of Viana.
Joan of Artois, Countess of Foix
Joan of Artois, Countess of Foix, Viscountess of Béarn( French:" Jeanne d' Artois"; 1289 – after 24 March 1350), was a French noblewoman, and the wife of Gaston I de Foix, Count of Foix, Viscount of Béarn.
From 1331 to 1347 she was imprisoned by her eldest son on charges of scandalous conduct, dissolution, and profligacy.
Gaston II, Count of Foix
Gaston II of Foix-Béarn
( 1308 – September 1343), son of Gaston I of Foix- Béarn and Jeanne of Artois, was the 10th Count of Foix.
In 1315, after the death of his father Gaston I, he became Count of Foix, and Viscount of Béarn, Marsan, Gabardan, Nébouzan and Lautrec under the regency of his mother, Jeanne of Artois.
Count Gaston II imprisoned his mother Jeanne d'Artois in 1331 at the Château of Foix, being later moved in turn to Orthez, Lourdes and Carbonne.
Gaston II married his cousin Eleanore de Comminges, daughter of Bernard VII of Comminges and Laura de Montfort.
Eleanore de Comminges brought, as a dowry, her rights to the County of Bigorre.
They had one son: Gaston III Febus, who succeeded his father as Count of Foix.
Gaston II had several illegitimate children:
His actions in 1339 during the conquest of the castle of Tartas resulted in him receiving the title of Viscount of Lautrec.
He was at the Siege of Algeciras( 1342 – 44) in southern Spain, which was led by King Alfonso XI of Castile.
He died of the plague at Seville in 1343.
Gaston I, Count of Foix
Gaston I of Foix or Gaston VIII of Foix-Béarn( 1287 – Maubuisson, 13 December 1315) was the 9th Count of Foix, the 22nd Viscount of Béarn and Co- Prince of Andorra.
He was a son of Roger- Bernard III, Count of Foix and Margaret of Montcada, the eldest daughter and heiress of Gaston VII of Béarn.
He succeeded his father in 1302 as Count Gaston I of Foix and Viscount Gaston VIII of Béarn, first under the regency of his mother.
He was probably present at the Battle of the Golden Spurs in 1302, and fought again for the King of France against the Flemish at the Battle of Mons- en- Pévèle in 1304.
When the cities of his County of Foix rebelled against the Royal tax collectors, because they raised the taxes to finance the expensive war against Flanders, Gaston supported his cities.
For this, the County was confiscated for a while by the Senechal of Carcassonne.
In 1308, he started a war against the Count of Armagnac, against the orders of the King, who had forbidden intra-French warfare.
Gaston was taken prisoner and locked up in the Châtelet.
He was only released after paying a ransom of 36,000 livres.
He also had armed conflicts with his uncle James II of Majorca and even with his own mother, who firmly ruled Foix during his many absences.
In 1310, he inherited the Viscounty of Marsan from his aunt Constance of Moncada.
When another uncle, Ermengol X, Count of Urgell, died without a male heir, Gaston claimed the County of Urgell, but was no match against King Alfonso IV of Aragon, who incorporated Urgell into the Crown of Aragon.
On his return from yet another war against Flanders, Gaston fell ill and died in the Maubuisson Abbey, near Pontoise.
His body was transferred to the Boulbonne Abbey, where it was buried alongside his ancestors.
Some records state he was buried in the now- demolished church of the Couvent des Jacobins in Paris.
Peyre de Rius
Peyre de Rius(" fl." 1344–86) was an Occitan troubadour from Foix.
He wrote under the patronage of Gaston Phoebus, Count of Foix, and Peter the Ceremonious, King of Aragon.
He is one of the few troubadours known by name who lived for a time at Peter's court in Barcelona.
His name in standardised Occitan is" Peire" or" Pèire", in Catalan it is" Pere", and in modern French" Pierre".
An obscure reference to a Pere Riu among some" jongleurs" from Puigcerdà near Foix in October 1344 may be to Peyre, but it is impossible to tell.
The Pedro who was a" jongleur" of the count of Foix, mentioned in an Aragonese register of June 1357, may be Peyre de Rius.
So may be Pere Ruiç( perhaps an error for Riuç), minstrel of the count of Foix, of July 1368.
Peyre appears frequently in the court registers of Aragon for the years between 1361 and 1381, often changing his precise occupation and his patron.
His first recorded appearance at the Aragonese court was 16 September 1361, when he was paid as a minstrel in the service of Gaston Phoebus.
The first reference to him as a troubadour is in a document of 19 January 1372, when the court was at Alcañiz; he was again in the service of the count of Foix.
In February 1373 he and Jacme Fluvia, both titled" trobador de danses"( or" dançescomposers of" dansas), received gifts from the queen, Eleanor of Sicily.
By 11 May 1373 he was again in the household of the king himself, and as a minstrel.
On 25 June 1380 he was in the service of Foix and a troubadour.
In his last appearance in documents, he is recorded as receiving gifts from the new queen, Sibil·la de Fortià, for service as a" trobador de cançons de casa del comte de Foix"( troubadour of" cansos" of the House of Foix).
Of Peyre's work only one" canso" survives, in the Cançoner Vega- Aguiló compiled in the 1420s.
Martín de Riquer, who gave the piece its first modern edition, could not identify Peyre's dialect nor his place of origin on the basis of his language.
The poem is dedicated to Gaston Phoebus and is an extended gloss on the three things which delight the count, according to the prologue of Gaston's" Livre de la chasstout mon temps me suis délité par espécial en trois chose: l'une est en armes, l'autre est en amours, et l'autre si est en chasse."
Peyre opens the work thus:
The count is named explicitly later(" Febus, le coms").
If the song is to be dated to the time when Peyre was consistently in or around Foix it would seem to pertain to the period 1344 – 57 or as late as 1373.
De Riquer has suggested that Peyre may be the Pere de Rius who was a" fidèle boutiller de notre chère fille l'infante Jeanne"( faithful butler of our dear daughter the" infanta" Joanna) under John I of Aragon, called The Hunter.
This Joanna( Juana de Daroca), the eldest daughter of John I, married Mathieu de Castelbon( on 24 March 1392), who had succeeded his uncle Gaston as count of Foix in 1391.
Gaston IV, Count of Foix
Gaston IV (27 November 1422 – 25 or 28 July 1472) was the sovereign Viscount of Béarn and the Count of Foix and Bigorre in France from 1436 to 1472.
He also held the viscounties of Marsan, Castelbon, Nébouzan, Villemeur and Lautrec and was, by virtue of the county of Foix, co-prince of Andorra.
From 1447 he was also Viscount of Narbonne.
Through his marriage to Eleonor, heiress of the Kingdom of Navarre, he also held the title of Prince of Navarre.
He was a son of John I, Count of Foix and Jeanne d'Albret.
His maternal grandparents were Charles d'Albret, Constable of France and co-commander of the French army, killed at the Battle of Agincourt, and his wife Marie de Sully.
Gaston married the Navarrese "Infanta", Eleonor, in 1436.
Her parents were John II of Aragon and Blanche I of Navarre.
At the time, Leonor appeared to have few prospects: her father was a younger son and brother of kings of Aragon, and Leonor had a brother, Charles of Viana, and an older sister, Blanca, standing between herself and the throne of Navarre.
However, family dissent and death eliminated both Charles and Blanca; Leonor's father usurped the Navarrese crown, to which he added in 1458 the throne of Aragon (his older brother having died without legitimate children) and, following the deaths of Charles and Blanca, promised the succession to Navarre to Leonor and her husband in return for their loyalty to him, which was given.
They had ten children:
Gaston, Prince of Viana
Gaston, Prince of Viana, also called Gaston de Foix (1445 – 23 November 1470), was the son of Gaston IV of Foix and Eleanor of Navarre, and was the heir of both.
As a Prince of Navarre, he was called "Prince of Viana".
He married Magdalena of Valois, a daughter of Charles VII of France and Marie of Anjou on 7 March 1461 at Lescar.
They had two children:
Gaston died in 1470 from wounds received in a jousting tournament in Libourne, Aquitaine, before his accession to the throne of Navarre.
Consequently, Francis I and Catherine
I rose to the throne successively, but it was Gaston's wife Magdalena who actually pulled the strings of the crown all the way to Catherine's marriage to John III of Albret in 1494, and her death in 1495.
Isabella, Countess of Foix
Isabella of Foix also known as" Isabella of Foix- Castelbon"( before 2 November 1361- 1428) was sovereign Countess of Foix and Viscountess of Béarn from 1399 until 1428.
She was Countess of Foix in her own right, but shared power with her husband and later with her son.
She succeeded as countess along with her husband upon the death of her childless brother Matthew.
Paolo Zoppo
Paolo Zoppo( early 16th century) was an Italian painter of the Renaissance period, mainly active in Brescia.
He died suddenly in the town of Desenzano.
He is known to have depicted in paint the sack of Brescia in 1512 by Gaston of Foix, Duke of Nemours.
John I, Count of Foix
John I, Count of Foix also known as" Jean de Foix- Grailly"( 1382 – 4 May 1436) was Count of Foix from 1428 until his death in 1436.
He succeeded his mother Isabella, Countess of Foix.
His father was Archambaud de Grailly.
