On 22 December 1536, Pole, already a deacon, was created a cardinal over Pole's own objections. He also became papal legate to England in February 1536/1537. Pope Paul III put him in charge of organising assistance for the Pilgrimage of Grace (and related movements), an effort to organise a march on London to demand Henry replace his ‘reformist’ advisers with more traditional, Catholic minds; neither Francis I of France nor the Emperor supported this effort, and the English government tried to have Pole assassinated. In 1539, Pole was sent to the Emperor to organise an embargo against England – the sort of countermeasure he had himself warned Henry was possible.
