The First War (1296–1328) began with the English invasion of Scotland in 1296, and ended with the signing of the Treaty of Edinburgh–Northampton in 1328. The Second War (1332–1357) began with the English-supported invasion by Edward Balliol and the 'Disinherited' in 1332, and ended in 1357 with the signing of the Treaty of Berwick. The wars were part of a great crisis for Scotland and the period became one of the most defining times in its history. At the end of both wars, Scotland retained its status as an independent state. The wars were important for other reasons, such as the emergence of the longbow as a key weapon in medieval warfare.
