What is the cause of the Hundred Years War?

The war between the French and English kingdoms, which lasted for 116 years, was called the Hundred Years War. The reasons for this conflict lie in the dynastic ties between the two royal houses. The English Plantagenets were relatives of the Capetian and claimed the throne of France. In addition, the English nobles wished to regain possession of land and wealth in France. The French hoped to annex Guyenne, which remained subordinate to the British under the treaty of 1259, to the crown’s possessions, and to return the Scottish King David II to the throne.
