Metternich had taken alarm at the outbreak of the Greek insurrection against Ottoman rule in 1821. Clear-sighted as he was according to his own lights, he had divined at once that this repudiation of the Ottoman Pādishāh’s authority by a handful of his Orthodox Christian subjects in the remote Morea was a menace to the authority of the Austrian Kaiser because the Greeks were claiming Western sympathy and assistance for their cause in the name of the Western principle of Nationality. Metternich represented to the Holy Alliance [whose other members were Russia and Prussia] insistently, though without success, that if their own principle of Legitimacy was to be maintained intact, the Greek insurgents must be boycotted as outlaws and Sultan Mahmūd be supported, in maintaining his dynastic rights, as one of the Lord’s Anointed. From the Legitimist standpoint, Metternich’s attitude on this occasion was entirely justified by the event. For the triumphant success of the Greek insurgents – a success which they owed to the friendly intervention of France, Great Britain, and Russia as much as to their own exertions – was an event of far more than local importance. The erection of a sovereign independent national Greek State in 1829-31 made it inevitable that every people in South-Eastern Europe should insist upon attaining its own national independence and national unity sooner or later; and thus the Greek insurrection of 1821 incidentally preordained the erection of Jugoslavia and Greater Rumania in 1918-20 [greater at the expense of Hungary]. Truly, Metternich’s senses had not deceived him when he heard the death-knell of the Danubian Hapsburg Monarchy in those reverberations from the clash of arms in the Morea which fell upon his ears in Vienna.

Metternich, the last survivor of 1815, died a month to the day before the armistice in the Italian War of 1859.
It is difficult to imagine Beethoven and Metternich living in the same city. They never met, though a film even worse than Amadeus suggests that they did.
