Elizabeth was born at Rhuddlan Castle, in Rhuddlan, Denbighshire, Wales on 7 August 1282. As a consequence of her place of birth, she is frequently referred to as Elizabeth of Rhuddlan.
She was the ninth daughter, and twelfth child born to King Edward I and Eleanor of Castile.
Rhuddlan Castle was erected by King Edward I in 1277 following the First Welsh War.
Elizabeth was only eight years old when her mother Eleanor died.
Elizabeth had three half-siblings (Thomas, Edmund, and Eleanor) by King Edward’s second marriage to Princess Margaret of France. These half-siblings were young enough to be her own children – her step-mother was about the same age as she.
In April 1285, when she was only three years old, she was betrothed to the future John 1, Count of Holland.
They were married on 8th January 1297 at Ipswich.
Despite an initial reluctance to do so, Elizabeth eventually travelled to Holland, prepared to spend the rest of her life there with her husband.
However the Count of Holland died on 10 November 1299 of dysentery, though there were rumours of his murder.
As they had no children, Elizabeth returned to England.
On 14 November 1302 she married at Westminster Abbey Humphrey de Bohun, 4th Earl of Hereford, 3rd of Essex, and hereditary Constable of England, one of the great officers of state (now known as Lord High Constable of England).
Humphrey was born in 1276 at Pleshey, Chelmsford Borough, Essex.
Elizabeth and Humphrey had an unknown number of children, maybe 11.
He died on 16 March 1322 and was buried at York Unitary Authority, York.
She died on 5 May 1316 as a result of complications following the birth of her daughter Isabel, who was to also die soon after her birth.
She was interred at Walden Abbey, Essex, together with her infant daughter and other members of the de Bohun family.
