===Third Coalition===
In December 1804, an Anglo-Swedish agreement led to the creation of the Third Coalition.{{sfn|Jorgensen|2004|pp=25–28}} British Prime Minister [[William Pitt the Younger]] spent 1804 and 1805 in a flurry of diplomatic activity geared towards forming a new coalition against France, and by April 1805, Britain and Russia had signed an alliance.{{sfn|Chandler|1966|p=331}}{{efn|The [[Baltic Sea]] was dominated by Russia, something Britain was not comfortable with, as it provided valuable commodities like timber, tar, and hemp which were crucial supplies to the British. Additionally, Britain supported the [[Ottoman Empire]] against Russian incursions towards the [[Mediterranean Sea]]. Meanwhile, French territorial rearrangements in Germany occurred without Russian consultation, and Napoleon's annexations in the [[Po River|Po valley]] increasingly strained relations between the two.{{sfn|Chandler|1966|p=328}}}} Having been defeated twice in recent memory by France and being keen on revenge, Austria joined the Coalition a few months later.{{sfn|Chandler|1966|p=331}}
