This article looks at two ‘oaths of the community’ of 1258. First, it shows that the oath of the community at Oxford has been widely misinterpreted by historians: it was an oath of mutual aid, not an oath binding the community to reform. Second, it looks at the order for all in the realm to take an oath in October 1258, which has never been fully examined before. This order aimed to bind the entire realm to the reform movement – it was proclaimed in Latin, French and English – yet no chroniclers mentioned it and no mechanism was provided for its enactment.
