"Blackwood's was conceived as a rival to the Whig-supporting Edinburgh Review. Compared to the rather staid tone of The Quarterly Review, the other main Tory work, Maga was ferocious and combative. This is due primarily to the work of its principal writer John Wilson, who wrote under the pseudonym of Christopher North. Never trusted with the editorship, he nevertheless wrote much of the magazine along with the other major contributors John Gibson Lockhart and William Maginn. Their mixture of satire, reviews and criticism both barbed and insightful was extremely popular and the magazine quickly gained a large audience.
For all its conservative credentials the magazine published the works of radicals of British romanticism such as Percy Bysshe Shelley and Samuel Taylor Coleridge. Through Wilson the magazine was a keen supporter of William Wordsworth, parodied the Byronmania common in Europe and angered John Keats, Leigh Hunt and William Hazlitt by referring to their works as the "Cockney School of Poetry"."

James Hogg played "a significant part in the founding of Blackwood's Edinburgh Magazine in 1817. The new magazine's fortunes were secured by the publication of the notorious ‘Chaldee manuscript’ in the number for October 1817. This satirical article was drafted by Hogg and revised and expanded by John Wilson and John Gibson Lockhart. Hogg already had contacts with tory circles through his friendship with Scott, and from 1817 onwards the tory group of writers associated with Blackwood's were to play an important part in his life. Hogg's dealings with the tory wits were never comfortable or easy (although he shared their interest in the traditions and customs of the old Scottish peasantry). Nevertheless Blackwood's was liberal in its payment of authors, and Hogg's frequent contributions to its pages provided him with a useful source of income." (ODNB)
