The opportunity arose in 1586. A former page of Mary's, Anthony
Babington, began organizing a plot to have courtiers assassinate
Elizabeth, incite a general Catholic uprising in England, and crown Mary.
A conspiracy that involved the overthrow of the government naturally

support of Philip II, who promised to send an expedition to help, once
Elizabeth was safely dead. But the plan depended ultimately on the
acquiescence of Mary, and to obtain this Babington had to communicate
with her.
