Original prompt & settings (JSON) ↗The dynastic challenge first appeared in two pieces of royal paperwork appointing Edward's continental lieutenants.
Two letters patent
In documents issued on 6 and 7 October 1337, Edward III used the title King of France while appointing continental allies as his lieutenants. The surviving record is these two letters patent, not one formal ceremony or declaration.
It was a tentative diplomatic claim rather than his regular royal style. Scholarly accounts distinguish this experiment from his open, official assumption of the French crown in 1340.
Why he reached for the title
Philip VI had declared Edward's Duchy of Aquitaine forfeit on 24 May 1337, amid disputes over homage, Gascon jurisdiction, Scotland and Edward's sheltering of the exiled Robert of Artois.
Edward was not rejecting a claim by Philip: Philip had occupied the French throne since 1328. Edward was denying Philip's kingship and advancing his own hereditary case.
The defiance on All Saints' Day
Later in October Edward referred to Philip of Valois who calls himself king of France, denying the title in diplomatic language.
On All Saints' Day his ambassadors, among them Bishop Henry Burghersh of Lincoln, delivered a defiance to Philip and explained Edward's hereditary claim. That defiance, delivered on 1 November, converted the feudal dispute into an explicitly dynastic one; Philip's confiscation of Aquitaine in May remains the conventional opening trigger of the war.

Date disputed. Sources disagree about when this happened.
What the sources leave uncertain
- October 1337 contains several related acts, not one securely defined “formal rejection”: title-bearing patents on 6–7 October, later hostile diplomatic wording, and a defiance delivered on 1 November.
- Scholarly accounts distinguish Edward’s tentative use of the title in 1337 from his open or official claim in 1340.
- The conventional beginning of the Hundred Years’ War is Philip’s confiscation of Aquitaine on 24 May 1337, so the October documents did not initiate hostilities by themselves.
