The Intercursus Magnus was a major and long-lasting commercial treaty signed in February 1496 by King Henry VII of England[1] and Duke Philip IV of Burgundy.

In 1485, the Lancastrian claimant Henry Tudor defeated the Yorkist king Richard III on Bosworth Field and married Elizabeth of York, daughter of Edward IV and sister to the Princes in the Tower, to unite the houses.

It was a major and brave act of domestic and foreign policy, thus, for Henry VII to issue a trade embargo — reciprocated by Duke Philip IV of Burgundy — as a result of Margaret's meddling.

[5] These certainties greatly aided English export of wool, and thus both Henry VII's treasury[6] and Flemish and Brabantine industry,[7] whilst also providing freedoms to the Hollandic and Zeelandic fisheries.

[2] The importance of the treaty for England, who still relied heavily on the wool trade through Antwerp, cannot be overstated and served as another major success for Henry in both his economic and foreign policy aims.
