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.
War of Saint-Sardos
The War of Saint-Sardos was a short war fought between the Kingdom of England and the Kingdom of France in 1324. The war was a clear defeat for the English, and led indirectly to the overthrowing of Edward II of England. The war can also be seen as one of the precursors of the Hundred Years' War.
