Legitimacy wins France a seat at Vienna
At the Congress of Vienna in 1814–15, Talleyrand represented a defeated France that the four victorious allies (Austria, Britain, Prussia, Russia) meant to exclude from real deliberations. He invoked the principle of 'legitimacy' (restoring rightful dynasties like the Bourbons) and championed the smaller excluded powers, then exploited the Saxony-Poland split to sign a secret defensive alliance with Austria and Britain in January 1815. The loser thereby became a necessary member of the concert that decided Europe's settlement.
