Once Magna Carta had been entered on to the Statute Roll in 1297, it became a potent means of challenging royal authority. In February 1310 the bishops, earls and barons petitioned King Edward II (r. 1307–27), claiming that he was extorting money from the realm in breach of the Great Charter. Having been threatened with deposition, the King agreed to the election of 21 Ordainers to reform the kingdom. The final version of the Ordinances was granted by Edward II in 1311, with many of its clauses repeating Magna Carta, including that the Church shall have its liberties unimpaired (no. 1) and that all evil counsellors should be expelled (no. 13). The Ordinances further asserted that ‘le grant chartre’ (the Great Charter) and the Forest Charter should be observed in all their points (nos. 6, 38). This document contains an initial draft of the Ordinances and the names of the Ordainers.
