=== Life Sketch ===
Berengaria of León (1204 – 12 April 1237) was the third wife but only empress consort of John of Brienne, Latin Emperor of Constantinople.
According to the chronicle of Alberic of Trois-Fontaines, Berengaria was a daughter of Alfonso IX of León and Berengaria of Castile. She was a younger sister of Ferdinand III of Castile and Alfonso of Molina.
Marriage
In 1217, Berengaria's brother Ferdinand III had inherited the throne of the Kingdom of Castile through abdication of their mother.
In 1223, John of Brienne, aged 53, visited Santiago de Compostela, as a supposed pilgrim. He was by then twice a widower. As a consequence of his visit to Santiago de Compostela, Alfonso IX invited him to marry his daughter Sancha and, presumably, through her inherit the Leonese throne. However Berengaria of Castile, a long time divorced and an inheritor in her own right of the Castilian throne, main advisor of her son Ferdinand III, offered one of her own daughters to John instead. Aging John chose Berengaria of León, from Alfonso's second marriage. The marriage took place at Toledo in 1224.
Empress
In 1229, the throne of the Latin Empire had been inherited by Baldwin II of Constantinople, a twelve-year-old boy. The barons of the Empire decided to secure the safety of the Empire by appointing a regent-Emperor for Baldwin. They chose John who accepted the assignment as a sort of Senior Tutor. In April 1229, John was proclaimed regent at Perugia. They did not arrive at Constantinople until 1231, when John was officially crowned in his new city.
Baldwin II remained the junior co-emperor and only heir to the throne. By agreement, 12-year-old Baldwin had been betrothed to around 5-years-old Marie of Brienne, the daughter of John and Berengaria, since 19 April 1229 to firmly establish the dynastic alliance of the two co-emperors and the western land for Crusades also, Spain.
The marriage did not take place until 1234, when Marie was about ten years old and Baldwin about seventeen.
Alberic of Trois-Fontaines records that John died on 27 March 1237, aged around 61. The "Obituaires de Sens Tome" of the Abbey of Maubuisson record that Berengaria died on 12 April 1237, aged around 33, surviving her husband by only sixteen days.
She is buried in a beautiful marble coffin in the Cathedral of Santiago de Compostela, Spain, but many books and tourist leaflets mention her as if she was Queen Berenguela of Castile, her mother.
Other books, however, mention this coffin as being that of another Berengaria (1228–1288) and/or other dates, her niece, daughter of her brother King Ferdinand III of Castile, sister of King Alfonso X of Castile. But this niece, Infanta Berengaria was a nun at the Monastery of las Huelgas, Burgos, of Royal patronage, where Berengaria of León's mother, Queen Berengaria of Castile, retired as a former monarch.
Further, Alfonso VIII of Castile and Eleanor of England, grandparents of Berengaria of León are buried there. Much later, Ferdinand III's and Alfonso X's bodies, also at Las Huelgas, would be moved to conquered Seville's new cathedral, where they are today.
Children
Berengaria and John had four known children:
1. Marie of Brienne, who married Baldwin II of Constantinople and was the mother of Philip I of Constantinople.
2. Alphonso of Brienne, Count of Eu and Grand Chamberlain of France.
3. John II of Brienne (c. 1230–1296), who in 1258 became Grand Butler of France. Married Jeanne, Dame de Chateaudun, daughter of Geoffrey VI, Viscount of Châteaudun. His second wife was Marie de Coucy, widow of Alexander II of Scotland.
4. Louis of Brienne, Viscount of Beaumont. He was the father of Henry de Beaumont.

2/. Introduction, para 1: --
"John of Brienne (c. 1170 – 27 March 1237), also known as John I, was King of Jerusalem from 1210 to 1225 and Latin Emperor of Constantinople from 1229 to 1237. He was the youngest son of Erard II of Brienne, a wealthy nobleman in Champagne. John, originally destined for an ecclesiastical career, became a knight and owned small estates in Champagne around 1200. After the death of his brother, Walter III, he ruled the County of Brienne on behalf of his minor nephew Walter IV (who lived in southern Italy)."
3/. Under the heading "Early life" : Para 1 --
"John was the youngest of the four sons of Erard II, Count of Brienne, and Agnes of Montfaucon.[1][2] He seemed "exceedingly old ... about 80"[3] to the 14-year-old George Akropolites in 1231;[4] if Akropolites' estimate was correct, John was born around 1150.[5][6] However, no other 13th-century authors described John as an old man.[5] His father referred to John's brothers as "children" in 1177 and mentioned the tutor of John's oldest brother, Walter III, in 1184; this suggests that John's brothers were born in the late 1160s.[7][8] Modern historians agree that John was born after 1168, probably during the 1170s.[9][10]"
4/. Under the heading "Family" : Para 1 --
"John's first wife (Maria the Marquise, born 1191) was the only child of Isabella I of Jerusalem and her second husband, Conrad of Montferrat.[143] Maria inherited Jerusalem from her mother in 1205.[144] John and Maria's only child, Isabella (also known as Yolanda), was born in late 1212.[29][28].
Stephanie of Armenia became John's second wife in 1214.[28] She was the only daughter of Leo II of Armenia and his first wife, Isabelle (niece of Sibylle, the third wife of Bohemond III of Antioch).[145] Stephanie gave birth to a son in 1220, but she and her son died that year.[73]
John married his third wife, Berengaria of León, in 1224;[146] she was born around 1204 to Alfonso IX of León and Berengaria of Castile.[147][148]
John and Berengaria's first child, Marie, was born in 1224.[97] Their first son, Alphonse, was born during the late 1220s.[84]
Berengaria's cousin, Louis IX of France, made him Grand Chamberlain of France and he acquired the County of Eu in France with his marriage.[149]
John's second son, Louis, was born around 1230.[84]
His youngest son, John, who was born in the early 1230s, was Grand Butler of France.[150]"
