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 (1369–89)
In 1376, the Black Prince died, and in April 1377, Edward III of England sent his Chancellor, Adam Houghton, to negotiate for peace with Charles, but when in June Edward himself died, Houghton was called home. The underaged Richard of Bordeaux succeeded to the throne of England. It was not until Richard had been deposed by his cousin Henry Bolingbroke that the English, under the House of Lancaster, could forcefully revive their claim to the French throne. The war nonetheless continued until the first of a series of truces was signed in 1389.
