The Anti-Jacobin, or, Weekly Examiner was an English newspaper founded by George Canning in 1797 and devoted to opposing the radicalism of the French Revolution. The Revolution polarized British political opinion in the 1790s, with conservatives outraged at the killing of the king Louis XVI of France, the expulsion of the nobles, and the Reign of Terror. Great Britain went to war against Revolutionary France. Conservatives castigated every radical opinion in Great Britain as "Jacobin" (in reference to the leaders of the Terror), warning that radicalism threatened an upheaval of British society. The Anti-Jacobin sentiment was expressed in print.William Gifford was its editor. Its first issue was published on 20 November 1797 and during the parliamentary session of 1797–98 it was issued every Monday.
The Anti-Jacobin was planned by Canning when he was Under-Secretary of State for Foreign Affairs. He secured the collaboration of George Ellis, John Hookham Frere, William Gifford, and some others. William Gifford was appointed working editor.
Canning founded it, in his words, "...to be full of sound reasoning, good principles, and good jokes and to set the mind of the people right upon every subject." One of Canning's biographers described its purpose as to "...deride and refute the ideas of the Jacobins, present the government's point of view on the issues of the day and expose the misinformation and misinterpretation which filled the opposition newspapers." In its first issue Canning said he and his friends:
...avow ourselves to be partial to the COUNTRY in which we live, notwithstanding the daily panegyrics which we read and hear on the superior virtues and endowments of its rival and hostile neighbours. We are prejudiced in favour of her Establishments, civil and religious; though without claiming for either that ideal perfection, which modern philosophy professes to discover in the more luminous systems which are arising on all sides of us.
