Aidan founds the monastery of Lindisfarne.

When Edwin, king of Northumbria, was killed in battle, the Christian mission in his lands collapsed.

At the request of Oswald, the new king, the abbot of Iona sent the Irish missionary Aidan to be the new bishop.

Near the royal castle of Bamburgh, he founded the island monastery of Lindisfarne, where many of the missionaries who converted the rest of England were trained. Aidan was made a saint.
