The Battle of Boroughbridge was fought on 16 March 1322 in England between a group of rebellious barons and King Edward II, near Boroughbridge, north-west of York. The culmination of a long period of antagonism between the King and Thomas, Earl of Lancaster, his most powerful subject, it resulted in Lancaster's defeat and execution. This allowed Edward to re-establish royal authority, and hold on to power for almost five more years.
Not in itself a part of the Wars of Scottish Independence, the battle is significant for its employment of tactics learned in the Scottish wars in a domestic, English conflict. Both the extensive use of foot soldiers rather than cavalry, and the heavy impact caused by the longbow, represented significant steps in military developments.
