Alexander saw an opportunity to push through his idea of a ‘general system’, and called for a new congress to deal with the Spanish and Neapolitan questions. Metternich suggested that they leave the matter to a conference of ministers in Vienna, but Alexander insisted on a full congress of monarchs, and Metternich was obliged to agree. He proposed they meet at Troppau (Opava) in Bohemia on 20 October in order to frame a set of rules governing when the allies should intervene in the affairs of other countries and when they should not.
