Hundred Years' War
Historians commonly divide the war into three phases separated by truces: the Edwardian War (1337–1360), the Caroline War (1369–1389), and the Lancastrian War (1415–1453). Local conflicts in neighbouring areas, which were contemporarily related to the war, including the War of the Breton Succession (1341–1365), the Castilian Civil War (1366–1369), the War of the Two Peters (1356–1369) in Aragon, and the 1383–85 crisis in Portugal, were availed by the parties to advance their agendas. Later historians adopted the term "Hundred Years' War" as a historiographical periodisation to encompass all of these events, thus constructing the longest military conflict in European history.
Hundred Years' War (1337–1360)
After the treaties of London failed Edward launched the Rheims campaign which, though largely unsuccessful, led to the Treaty of Brétigny which settled certain lands in France on Edward for renouncing his claim to the French throne. This was in part caused by Black Monday (1360), the freak storm that devastated the English army and forced Edward III into peace talks. This peace lasted nine years; but then began a second phase of hostilities known as the Caroline War.
