what was its result?
Laws against recusancy were strengthened; the Popish Recusants Act returned England, introduced a sacramental test, and an Oath of Allegiance
Gunpowder Plot
Greater freedom for Roman Catholics to worship as they chose seemed unlikely in 1604, but the discovery of such a wide-ranging conspiracy, the capture of those involved, and the subsequent trials, led Parliament to consider introducing new anti-Catholic legislation. The event also destroyed all hope that the Spanish would ever secure tolerance of the Catholics in England. In the summer of 1606, laws against recusancy were strengthened; the Popish Recusants Act returned England to the Elizabethan system of fines and restrictions, introduced a sacramental test, and an Oath of Allegiance, requiring Catholics to abjure as a "heresy" the doctrine that "princes excommunicated by the Pope could be deposed or assassinated".

Gunpowder Plot [SEP] Aftermath
The plot may also have influenced his later work, "Paradise Lost". The Gunpowder Plot was commemorated for years by special sermons and other public acts, such as the ringing of church bells. It added to an increasingly full calendar of Protestant celebrations that contributed to the national and religious life of 17th-century England, and has evolved into the Bonfire Night of today. In "What If the Gunpowder Plot Had Succeeded?" historian Ronald Hutton considered the events which might have followed a successful implementation of the plot, and the destruction of the House of Lords and all those within it. He concluded that a severe backlash against suspected Catholics would have followed, and that without foreign assistance a successful rebellion would have been unlikely; despite differing religious convictions, most Englishmen were loyal to the institution of the monarchy.
