As for the other Powers, they were either helpless or torpid.

The King of Sweden was venting his spleen upon Prussia.

Italy, South Germany, Holland, and Spain were at Napoleon's beck; and the policy of England under the new Grenville-Fox Ministry inclined strongly towards peace.
There seemed, then, every chance of founding the supremacy of France upon lasting foundations, if the claims of Britain and Austria received reasonable satisfaction.

Napoleon also seems to have wanted peace for the consolidation of his power in Europe and the extension of his colonies and commerce.

As at the close of all his land campaigns, his thoughts turned to the East, and on January 31st, 1806, he issued orders to Decres which, far from showing any despair as to the French navy, foreshadowed a vigorous naval and colonial policy; while his moves on the Dalmatian coast, and the despatch of Sebastiani on a mission to the Porte, revealed the magnetic attraction which the Levant still had for him.
A peculiar interest therefore attaches to the negotiations for peace in 1806, especially as they were pushed on by that generous orator, Fox, who had so long pleaded for a good understanding with France.
