The Ordinances of 1311 were a series of regulations imposed upon King Edward II by the peerage and clergy of the Kingdom of England to restrict the power of the king. The twenty-one signatories of the Ordinances are referred to as the Lords Ordainers, or simply the Ordainers. English setbacks in the Scottish war, combined with perceived extortionate royal fiscal policies, set the background for the writing of the Ordinances in which the administrative prerogatives of the king were largely appropriated by a baronial council. The Ordinances reflect the Provisions of Oxford and the Provisions of Westminster from the late 1250s, but unlike the Provisions, the Ordinances featured a new concern with fiscal reform, specifically redirecting revenues from the king's household to the exchequer.
Just as instrumental to their conception were other issues, particularly discontent with the king's favourite, Piers Gaveston, whom the barons subsequently banished from the realm. Edward II accepted the Ordinances only under coercion, and a long struggle for their repeal ensued that did not end until Thomas of Lancaster – the leader of the Ordainers – was executed in 1322.
When Edward II succeeded his father Edward I on 7 July 1307, the attitude of his subjects was generally one of goodwill toward their new king. However, discontent was brewing beneath the surface. Some of this was due to existing problems left behind by the late king, while much was due to the new king's inadequacies. The problems were threefold. First there was discontent with the royal policy for financing wars. To finance the war in Scotland, Edward I had increasingly resorted to so-called prises – or purveyance – to provision the troops with victuals. Though a perfectly legitimate method of raising money, the peers felt that the purveyance had become far too burdensome and compensation was in many cases inadequate or missing entirely. In addition, they did not like the fact that Edward II took prises for his household without continuing the war effort against Scotland, causing the second problem. While Edward I had spent the last decade of his reign relentlessly campaigning against the Scots, his son abandoned the war almost entirely. In this situation, the Scottish king Robert Bruce soon took the opportunity to regain what had been lost. This not only exposed the north of England to Scottish attacks, but also jeopardized the possessions of the English baronage in Scotland.
