Sir William Wallace was a Scottish knight who became one of the main leaders during the First War of Scottish Independence.

The First War of Scottish Independence was the first of a series of wars between English and Scottish forces. It lasted from the English invasion of Scotland in 1296 until the de jure restoration of Scottish independence with the Treaty of Edinburgh–Northampton in 1328. De facto independence was established in 1314 at the Battle of Bannockburn. The wars were caused by the attempts of the English kings to establish their authority over Scotland while Scots fought to keep English rule and authority out of Scotland.
