[330] [Robert Stewart, Viscount Castlereagh, afterwards Marquis of Londonderry (1769-1822), who had been labouring under a "mental delirium" (Letter of Duke of Wellington, August 9, 1822), committed suicide by cutting his throat with a penknife (August 12, 1822). He was the uncompromising and successful opponent of popular causes in Ireland, Italy, and elsewhere, and, as such, Byron assailed him, alive and dead, with the bitterest invective. (See, for instance, the "Dedication" to Don Juan, stanzas xi.-xvi., sundry epigrams, and an "Epitaph.") In the Preface to Cantos VI., VII., VIII., of Don Juan, he justifies the inclusion of a stanza or two on Castlereagh, which had been written "before his decease," and, again, alludes to his suicide. (For an estimate of his career and character, see Letters, 1900, iv. 108, 109, note 1; and for a full report of the inquest, The Annual Biography, 1823, pp. 56-62.)]

[332] [George Canning (1770-1827) succeeded Lord Londonderry as Foreign Secretary, September 8, 1822. He was not a persona grata to George IV., who had been offended by Canning's neutral attitude, as a minister, on the question of the Queen's message (June 7, 1820), and by his avowal "of an unaltered regard and affection" for that "illustrious personage" herself. There was, too, the prospect of Catholic Emancipation. In 1821 he had spoken in favour of Plunket's bills, and, the next year (April 30, 1822), he had brought in a bill to remove the disabilities of Roman Catholic peers from sitting in the House of Lords. If Canning persisted in his advocacy of Catholic claims, the king's conscience might turn restive, and urge him to effectual resistance. Hence the warning in lines 563-567.]
