"Sacheverell's Sermon" refers to a controversial sermon delivered by Henry Sacheverell, an English clergyman, in 1709. The sermon criticized the government and promoted the idea of divine right, which argued that monarchs were chosen by God. This sparked significant public debate and political tension, as it was seen as a challenge to the authority of the Whig government. The sermon led to a trial in 1710, where Sacheverell was accused of seditious libel. He was ultimately suspended from preaching for three years, but his supporters rallied around him, leading to a surge in Tory sentiment. This event highlighted the deep political divisions in England during that period.
