Anthony Munday was a protege of John Dudley, Earl of Leicester. Leicester himself was a member of the progressive Protestant nobility in Elizabethan England, which sought to turn completely away from Rome and toward Geneva. These progressives wanted vernacular translations of great works such as the Bible and the classics. They aimed at founding an English and Protestant tradition of literature.

In 1579 Philip II of Spain continued to press for an alliance with Queen Elizabeth. Elizabeth seriously considered marrying the Due d'Alencon. Such a marriage would cement ties between England and France. The leading progressives, Leicester, Walshingham and Cecil could tolerate neither one of these Roman Catholic alliances. Thus, Leicester intensified his patronage of Puritan propagandists.

When the Campion controversy arose in 1581, it proved a boon to Leicester and the progressives. Here was an opportunity to garner Elizabeth's support, if they could prove that Jesuits and Roman Catholics were plotting regicide and the return of England to Roman Catholicism.

Between 1581 and 1584 Munday produced a series of pamphlets designed to arouse English opinion against “popish recusants.” This essay deals with one of these pamphlets: A discoverie of Edmund Campion and his confederates, their most horrible and traiterous practices against her majestye's most royal person and realm. … In this essentially propagandistic tract, Munday equates priestly activity of the Jesuits with subversion. This equation was based upon a Parliamentary statute of 1581, which declared that priests sent from abroad to convert Englishmen were guilty of treason.
