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.
Second Hundred Years' War
The Second Hundred Years' War (c. 1689 – c. 1815) is a periodization or historical era term used by some historians to describe the series of military conflicts between Great Britain and France that occurred from about 1689 (or some say 1714) to 1815. For the context see International relations, 1648–1814.
