TROPPAU (Polish, Oppava; Czech, Opava), the capital of the Austrian duchy and crown land of Silesia, 180 m.
Troppau was founded in the 13th century; but almost its only claim to historical mention is the fact that in 1820 the monarchs of Austria, Russia and Prussia met here to deliberate on the tendencies of the Neapolitan revolution.
This congress of Troppau, however, left nearly the whole matter to be considered and decided at Laibach.
CONGRESS OF TROPPAU, a conference of the allied sovereigns or their representatives to discuss a concerted policy with regard to the questions raised by the revolution in Naples of July 1820.
In a series of conferences - to which the representatives of Great Britain and France were not admitted, on the excuse that they were only empowered to "report," not to "decide" - was drawn up the famous preliminary protocol signed by Austria, Russia and Prussia on the 19th of November.
The main pronouncement of the "Troppau Protocol" is as follows: "States which have undergone a change of government due to revolution, the result of which threaten other states, ipso facto cease to be members of the European Alliance, and remain excluded from it until their situation gives guarantees for legal order and stability.
