Political radical, poet and erstwhile friend of Coleridge. Arrested on a charge of treason in 1794, Thelwall became first a farmer at Llyswen, Wales, then a speech therapist, journalist and itinerant lecturer on elocution. He remained a Radical but faded from the forefront of the political scene after the 1790s. Though they came to disagree on politics, Southey retained a good deal of affection for Thelwall.
