Joan, Princess of Wales and Lady of Snowdon, also known by her Welsh name of Siwan, (c. 1191 – 2 February 1237) was the wife of Llywelyn the Great, Prince of Wales and Gwynedd and effective ruler of most of Wales.
Little is known about her early life. Her mother's name is known only from Joan's obituary in the Tewkesbury Annals, where she is called "Regina Clementina" (Queen Clemence); there is no evidence that her mother was in fact of royal blood. Joan may have been born in France, and probably spent part of her childhood there, as King John had her brought to the Kingdom of England from Normandy in December 1203 in preparation for her wedding to prince Llywelyn ab Iorwerth.
Thomas Pennant, in "Tours in Wales”, Volume 2, published London, 1810, writes : “It is said that Llewelyn the Great had near this place [Trefriw] a palace; ... The church of Trefriw was originally built by Llewelyn, for the ease of his princess, who before was obliged to go on foot to Llanrhychwyn, a long walk among the mountains.”
Joan married Llywelyn the Great between December 1203 and October 1204. The wedding was celebrated at St Werburgh's Abbey in Chester. She and Llywelyn had at least two children together:
- Elen ferch Llywelyn (Helen or Ellen) (1207–1253), married (1) John the Scot, Earl of Chester and (2) Robert II de Quincy
- Dafydd ap Llywelyn (c. 1212-1246) married Isabella de Braose, died at Abergwyngregyn.
Some of Llywelyn's other recorded children may also have been Joan's:
- Gwladus Ddu (1206–1251), married (1) Reginald de Braose and (2) Ralph de Mortimer (had issue).
- Susanna, who was sent to England as a hostage in 1228.
- Angharad ferch Llywelyn
- Margaret, who married (1) Sir John de Braose (called 'Tadody'), the grandson of William de Braose, 4th Lord of Bramber. She married (2) Sir Walter de Clifford and had children by both husbands.
In April 1226 Joan obtained a papal decree from Pope Honorius III, declaring her legitimate on the basis that her parents had not been married to others at the time of her birth, but without giving her a claim to the English throne.
Adultery with William de Braose
At Easter 1230, William de Braose, who was Llywelyn's prisoner at the time, was discovered with Joan in Llywelyn's bedchamber. William de Braose was hanged on 2 May 1230, according to local folklore at Abergwyngregyn; the place was known as 'Gwern y Grog'. A recent suggestion is that the execution might have taken place at Crogen near Bala (crogi = to hang).
Joan was placed under house arrest for twelve months after the incident. She was then, according to the Chronicle of Chester, forgiven by Llywelyn, and restored to favour. She may have given birth to a daughter early in 1231.
Joan was never called Princess of Wales, but, in Welsh, "Lady of Wales". She died at the royal home at Abergwyngregyn, on the north coast of Gwynedd, in 1237. Llywelyn's great grief at her death is recorded; he founded a Franciscan friary on the seashore at Llanfaes, opposite the royal home, in her honour. The friary was consecrated in 1240, shortly before Llywelyn died. It was destroyed in 1537 by Henry VIII of England during the Dissolution of the Monasteries. Joan's stone coffin can be seen in Beaumaris parish church, Anglesey. Above the empty coffin is a slate panel inscribed: "This plain sarcophagus, (once dignified as having contained the remains of Joan, daughter of King John, and consort of Llewelyn ap Iowerth, Prince of North Wales, who died in the year 1237), having been conveyed from the Friary of Llanfaes, and alas, used for many years as a horsewatering trough, was rescued from such an indignity and placed here for preservation as well as to excite serious meditation on the transitory nature of all sublunary distinctions. By Thomas James Warren Bulkeley, Viscount Bulkeley, Oct 1808"
- Joan and her affair with William de Braose is the subject of Saunders Lewis's Welsh verse play Siwan.
- Edith Pargeter's novel The Green Branch is set in Wales and the Welsh Marches in 1228-1231, when Llewelyn ruled Gwynedd and most of the rest of Wales.
- Although named Joanna, Joan is the main character of Sharon Kay Penman's novel Here Be Dragons.
