Sir William Wallace (Scottish Gaelic: Uilleam Uallas, pronounced [ˈɯʎam ˈuəl̪ˠəs̪]; Norman French: William le Waleys; c. 1270 – 23 August 1305) was a Scottish knight who became one of the main leaders during the First War of Scottish Independence.Along with Andrew Moray, Wallace defeated an English army at the Battle of Stirling Bridge in September 1297. He was appointed Guardian of Scotland and served until his defeat at the Battle of Falkirk in July 1298. In August 1305, Wallace was captured in Robroyston, near Glasgow, and handed over to King Edward I of England, who had him hanged, drawn and quartered for high treason and crimes against English civilians.

Since his death, Wallace has obtained an iconic status far beyond his homeland. He is the protagonist of Blind Harry's 15th-century epic poem The Wallace and the subject of literary works by Jane Porter and Sir Walter Scott, and of the Academy Award-winning film Braveheart.
