Quizplus · Accepted Answer

The Congress of Vienna was an international meeting held in 1814-1815 in Vienna, Austria, with the goal of redrawing the map of Europe after the end of the Napoleonic Wars. The meeting involved representatives from all major European powers, and resulted in a new balance of power in Europe and the establishment of the Concert of Europe to maintain this balance. The Versailles Conference was held in 1919 after World War I, the Council of Trent was a 16th-century council of the Catholic Church, and while the Concert of Europe was established at the Congress of Vienna, it was not the primary purpose of the meeting.
