Congress of Laibach
The Congress of Laibach was a conference of the allied sovereigns or their representatives, held in 1821 as part of the Congress System (the forerunner of the Concert of Europe) which was the decided attempt of the five Great Powers to settle international problems after the Napoleonic Wars through discussion and collective weight rather than on the battlefield. A result of the Congress was the authorization of Austrian intervention in the Kingdom of the Two Sicilies in order to quell a liberal uprising.
