The Malus Intercursus was a commercial treaty signed in April 1506 by King Henry VII of England and Duke Philip IV of Burgundy.

Another term of the treaty forced Philip to surrender custody of Edmund de la Pole, 3rd Duke of Suffolk to Henry VII.

In return, Henry VII recognised Philip and his wife Joanna of Castile as the legitimate rulers of the Kingdom of Castille, and allowed them to safely leave England.

[1] A shipwreck in 1506 left Philip stranded in England en route to claiming the Castilian inheritance of his wife, Joanna the Mad.

After handing over de la Pole, Philip and Joanna were allowed to leave England after a forced stay of six weeks.
