AHC: Casus Belli Song scenario

You challenge, should you accept it, is to have, after 1648 but before 1830, a war where Russia, Denmark and France are on one side, and England or the UK is on the other side.

Bonus points if a) it is started by England/UK's actions in the Holy Roman Empire, and/or b) the war causes a political crisis in Britain.
 
as for the war see otl during the napoleanic wars for a time france denmark and russia were allied against great britian
 
Isn't this more or less OTL? During the Napoleonic wars, Britain was simultaneously fighting the Gunboat War against Denmark-Norway, the Anglo-Russian War, and the ever-present war against France. So 1807-1812 IOTL fulfills this AHC.
