She was the eldest daughter of Sancho VI of Navarre and Sancha of Castile.
As is the case with many of the medieval English queens, relatively little is known of her life.
Traditionally known as "the only English queen never to set foot in the country", she may in fact have visited the country after her husband's death, but did not do so before, nor did she see much of him during her marriage, which was childless.
She did (unusually for the wife of a Crusader) accompany him on the start of the Third Crusade, but mostly lived in his French possessions, where she gave generously to the church, despite difficulties in collecting the pension
she was due from Richard's brother and successor John after she became a widow.

Richard I of England
Richard I (8 September 1157 – 6 April 1199) was King of England from 1189 until his death.
He also ruled as Duke of Normandy, Aquitaine and Gascony, Lord of Cyprus, Count of Poitiers, Anjou, Maine, and Nantes, and was overlord of Brittany at various times during the same period.
He was the third of five sons of King Henry II of England and Duchess Eleanor of Aquitaine and seemed unlikely to become king, but all of his brothers except the youngest, John, predeceased their father.
Richard was known as or Richard the Lionheart because of his reputation as a great military leader and warrior.
He was also known in , because of his reputation for terseness.
By the age of 16, Richard had taken command of his own army, putting down rebellions in Poitou against his father.
Richard was a central Christian commander during the Third Crusade, leading the campaign after the departure of Philip II of France and achieving considerable victories against his Muslim counterpart, Saladin, although he did not retake Jerusalem from Saladin.
Richard spoke both French and Occitan.
He was born in England, where he spent his childhood; before becoming king, however, he lived most of his adult life in the Duchy of Aquitaine, in the southwest of France.
Following his accession, he spent very little time, perhaps as little as six months, in England.
Most of his life as king was spent on Crusade, in captivity, or actively defending his lands in France.
Rather than regarding his kingdom as a responsibility requiring his presence as ruler, he has been perceived as preferring to use it merely as a source of revenue to support his armies.
Nevertheless, he was seen as a pious hero by his subjects.
He remains one of the few kings of England remembered more commonly by his epithet than his regnal number, and is an enduring iconic figure both in England and in France.
