Wulfstan (died December 956) was Archbishop of York between 931 and 952. He is often known as Wulfstan I, to separate him from Wulfstan II, Archbishop of York.
Early life
Wulfstan was consecrated in 931. He was presumably appointed with the consent of King Æthelstan, and attested all of the king's charters between 931 and 935. Between 936 and 41, however, he was absent from the king's court, for unknown reasons.
In 939, King Olaf Guthfrithson of Dublin invaded Northumbria and occupied York. King Edmund of England marched north to remove Olaf from York, but in 940 Wulfstan and Archbishop Wulfhelm of Canterbury arranged a treaty that ceded the area between Watling Street and the border of Northumbria to Olaf. But Olaf died in late 940, and his rule in York was inherited by his cousin, Olaf Sitricson who became King of Jórvík. In 944, Olaf Sitricson and his co-ruler Ragnald Guthfrithson were driven out from York; the chronicler Æthelweard wrote that it was "Bishop Wulfstan and the eoldormen of the Mercians" who were responsible for their expulsion. The Anglo-Saxon Chronicle version D says that "because accusations had often been made to the king against him", Eadred arrested Wulfstan and took him to Iudanbyrig (the location of which is not known). He died at Oundle, Northamptonshire, on 16
