Bertha of Aragon
Bertha of Aragon( c. 1075 – bef. 1111) was a Queen consort of Aragon and Navarre.
Nothing is known about her childhood or the names of her parents, it is believed that she is Italian since her name was" Berta", which is Italian.
She was married to Peter I of Aragon in 1097, shortly after the death of Peter's first wife, Agnes of Aquitaine, with whom he had two children: Peter and Isabella.
Bertha and Peter had no children.
Peter and Isabella were both dead by 1104 and King Peter needed an heir.
They had no children and Peter died the following year.
The crown of Aragon and Navarre passed to Alfonso who was the half brother of Peter.
Bertha got a dower but Alfonso got all of Peter's lands.
It is unknown when Bertha died or where she died.
Genealogist Szabolcs de Vajay has speculated that Bertha may have been a daughter of Peter I, Count of Savoy, and another Agnes of Aquitaine, perhaps the Agnes who was the final wife of Peter's father Ramiro I of Aragon and first- cousin of Peter's own first wife.
Alfonso II of Aragon
Alfonso II (1–25 March 1157 – 25 April 1196), called the Chaste or the Troubadour, was the King of Aragon and, as Alfons I, the Count of Barcelona from 1164 until his death.
The eldest son of Count Ramon Berenguer IV of Barcelona and Queen Petronilla of Aragon, he was the first King of Aragon who was also Count of Barcelona.
He was also Count of Provence, which he conquered from Douce II, from 1166 until 1173, when he ceded it to his brother, Ramon Berenguer III.
His reign has been characterised by nationalistic and nostalgic Catalan historians, as "l'engrandiment occitànic" or "the Pyrenean unity": a great scheme to unite various lands on both sides of the Pyrenees under the rule of the House of Barcelona.
Gülbahar Hatun (wife of Mehmed II)
Gülbahar Hatun( 1432 – 1492) was the consort of Sultan Mehmed II, and mother of Sultan Bayezid II of the Ottoman Empire and the grandmother of Selim I.
Peter II of Aragon
Peter II the Catholic (July 1178 – 12 September 1213) was the King of Aragon and Count of Barcelona from 1196 to 1213.
He was born in Huesca, the son of Alfonso II of Aragon and Sancha of Castile.
In 1205 he acknowledged the feudal supremacy of the papacy and was crowned in Rome by Pope Innocent III, swearing to defend the Catholic faith (hence his epithet, "the Catholic").
He was the first king of Aragon to be crowned by the pope.
In the first decade of the thirteenth century he commissioned the "Liber feudorum Ceritaniae", an illustrated codex cartulary for the counties of Cerdagne, Conflent, and Roussillon.
On 15 June 1204 he married (as her third husband)
Marie of Montpellier, daughter and heiress of William VIII of Montpellier by Eudocia Comnena.
She gave him a son, James, but Peter soon repudiated her.
Marie was popularly venerated as a saint for her piety and marital suffering, but was never canonized; she died in Rome in 1213.
Marie also perhaps bore Peter II a daughter, "Sancha", at Collioure in October 1205 according to Christian Nique.
("Sancha" was born in 1206 according to other accounts; in 1208 according to Mark Gregory Pegg, but February 1208 is more likely the year the couple's son was born).
Sancha was betrothed to Raymond VII the son Count Raymond VI of Toulouse, not long after her birth, according to Nique, only days (sources differ as to how long).
The marriage contract included Marie's inheritance, Montpellier, which was to be passed to the child immediately should something happen to Peter, says Nique, citing documents discovered in 1850, something Marie would at first not agree to, but finally agreed to a few months later, stating that she had agreed under pressure.
However the child's younger brother James makes no mention of her
and Sancha was apparently dead before the New Year, according to Nique's information.
He participated in the Battle of Las Navas de Tolosa in 1212 which marked the turning point of Muslim domination in the Iberian peninsula.
The Crown of Aragon was widespread in the area that is now southwestern France, but which at that time was under the control of vassal local princes, such as the Counts of Toulouse.
The Cathars or Albigenses rejected the authority and the teachings of the Catholic Church.
Innocent called upon Philip II of France to suppress the Albigenses.
Under the leadership of Simon of Montfort a campaign was launched.
The Albigensian Crusade, begun in 1209, led to the slaughter of approximately 20,000 men, women and children, Cathar and Catholic alike.
Over the course of twenty years military campaigns essentially destroyed the previously flourishing civilization of Occitania and by 1229 brought the region firmly under the control of the King of France, and the Capetian dynasty from the north of France.
Peter returned from Las Navas in autumn 1212 to find that Simon de Montfort had conquered Toulouse, exiling Count Raymond VI of Toulouse, who was Peter's brother-in-law and vassal.
Peter crossed the Pyrenees and arrived at Muret in September 1213 to confront Montfort's army.
He was accompanied by Raymond of Toulouse, who tried to persuade Peter to avoid battle and instead starve out Montfort's forces.
This suggestion was rejected.
The Battle of Muret began on 12 September 1213.
The Aragonese forces were disorganized and disintegrated under the assault of Montfort's squadrons.
Peter himself was caught in the thick of fighting, and died as a result of a courageous last stand.
He was thrown to the ground and killed.
The Aragonese forces broke in panic when their king was slain and Montfort's crusaders won a crushing victory.
The nobility of Toulouse, vassals of the Crown of Aragon, were defeated.
The conflict culminated in the Treaty of Meaux-Paris in 1229, in which the integration of the Occitan territory into the French crown was agreed upon.
Upon Peter's death, the kingdom passed to his only son by Marie of Montpellier, the future James the Conqueror.
