The treaty was intended to draw the powers of the Sixth Coalition into a closer alliance in case France rejected the peace terms they had recently offered.

[1] Following discussions in late February 1814, representatives of Austria, Prussia, Russia, and the United Kingdom reconvened a meeting at Chaumont, Haute-Marne, on 1 March 1814.
The resulting Treaty of Chaumont was signed on 9 or 19 March 1814 although it was dated 1 March by Emperor Alexander I of Russia, Holy Roman Emperor Francis II (with Prince Metternich), King Frederick William III of Prussia, and British Foreign Secretary Lord Castlereagh.
The treaty called for Napoleon to give up all conquests and thus to revert France to its pre-revolutionary borders in exchange for a ceasefire.
