Emma (or Emme) of Anjou (c.1140–c.1214)  was an illegitimate daughter of Geoffrey Plantagenet, Count of Anjou, and half-sister of King Henry II of England. She was married to Dafydd ab Owain Gwynedd, a Welsh prince.  She is occasionally confused with Emma de Laval (1200-1264), the daughter of Guy V de Laval.  Emma married Dafydd in the summer of 1174, after an unsuccessful rebellion by the queen, Eleanor of Aquitaine, and her older sons had led her half-brother the king to disperse Eleanor's court in Aquitaine and bring Emma back to England. 
Emma had four children by Dafydd:

In 1196, Emma and her husband, at the request of their son, Owain,  gave property to Haughmond Abbey.  Shortly afterwards, Dafydd was deposed by his nephew, Llywelyn the Great, and was forced into exile in England, where he died in 1203.

The history of Gwynedd in the High Middle Ages is a period in the History of Wales spanning the 11th through the 13th centuries. Gwynedd, located in the north of Wales, eventually became the most dominant of Welsh polities during this period. Contact with continental courts allowed for Gwynedd to transition from a petty kingdom into an increasingly sophisticated principality of seasoned courtiers capable of high level deplomacy and representation; not only with the Angevine kings, but also the king of France and the Papal See. Distinctive achievements in Gwynedd include further development of Medieval Welsh literature, particularly poets known as the Beirdd y Tywysogion associated with the court of Gwynedd; the reformation of bardic schools; and the continued development of Cyfraith Hywel. All three of these further contributed to the development of a Welsh national identity in the face of Anglo-Norman encroachment of Wales.
