The Accord of Winchester is the 11th-century document that establishes the primacy of the Archbishop of Canterbury over the Archbishop of York.

It originated in a dispute over primacy between Thomas, the archbishop of York, and Lanfranc, the new Norman archbishop of Canterbury, soon after the latter had taken office. The case was first heard by King William I at the old Saxon royal capital of Winchester at Easter (8 April) 1072, in the royal chapel in the castle. It was then heard at Windsor at Pentecost (27 May), where the final settlement was made, with William deciding in Lanfranc's favour, and formalised in this document.

This did not end the Canterbury–York dispute over the primacy, as it continued for a number of years after this.

Signatories

When King William and Queen Matilda signed the document with crosses, it did not necessarily mean they were unused to writing, infirm or even illiterate. They and all the bishops signed with crosses, as illiterate people would later do, but they did so in accordance with current legal practice, not because they or the bishops could not write their own names.

It (in the CCA-DCc-ChAnt/A/2 version) was also signed by the Archbishop of Canterbury the Archbishop of York, who signed '' (I concede), unlike all the other signatories, who signed '' (I subscribe) Wulfstan, bishop of Worcester Walkelin, bishop of Winchester Remigius de Fécamp, bishop of Lincoln, who had moved his seat to that city earlier that year Herfast, bishop of Thetford Hubert, 'lector' of the Roman Church and papal legate of Pope Alexander II (the pope who had backed King William's invasion of England and had backed Lanfranc in the dispute)
