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
Difficulties in raising taxes and revenue hampered the ability of the French to fight the English. At this point, the war's pace had largely slowed down, and both nations found themselves fighting mainly through proxy wars, such as during the 1383–1385 Portuguese interregnum. The independence party in the Kingdom of Portugal, which was supported by the English, won against the supporters of the King of Castile's claim to the Portuguese throne, who in turn was backed by the French.
