Monteagle Letter

The Monteagle Letter was a covert message sent in 1641 warning of a planned attack on Parliament by Catholic conspirators, possibly to restore Catholicism in England. It was anonymous but hinted at a conspiracy that could threaten the government, leading to increased fears of Catholic plots. The letter was intended to alert authorities, though its authorship remains uncertain. Its discovery contributed to heightened tensions between Protestants and Catholics, and shaped political and religious conflicts during that period.
