World Congress Industrial Start
World Congress begins in the Industrial Era for realism. Earliest known gathering of nations occurred after the Napoleonic Wars.
"The Congress of Vienna was a meeting of ambassadors of European states chaired by Austrian statesman Klemens von Metternich, and held in Vienna from November 1814 to June 1815, though the delegates had arrived and were already negotiating by late September 1814. The objective of the Congress was to provide a long-term peace plan for Europe by settling critical issues arising from the French Revolutionary Wars and the Napoleonic Wars.
In a technical sense, the Congress of Vienna was not properly a congress: it never met in plenary session, and most of the discussions occurred in informal, face-to-face sessions among the Great Powers of Austria, Britain, France, Russia, and sometimes Prussia, with limited or no participation by other delegates. On the other hand, the congress was the first occasion in history where, on a continental scale, national representatives came together to formulate treaties instead of relying mostly on messages among the several capitals. The Congress of Vienna settlement, despite later changes, formed the framework for European international politics until the outbreak of the First World War in 1914". – Wikipedia
