Coalition mechanics help.

[Apple.the.Great]

I'm playing as England, and having successfully won the Hundred Years War and PU'd France, I've now set most of Western Europe against me and in fact Munster has declared war against me, forcing me into a war against a large coalition. However, I've noticed that some of the coalition have not declared war on me (Burgundy and Austria importantly) and my ally Aragon has not joined me automatically (and won't join me now because it's been more than 60 days). Why have some of the coalition not declared war on me as part of the coalition, since I thought it was automatic, and if I declare war on a member of the coalition that I'm not at war with (Leinster), would it just bring in an extra opponent to my existing war against this coalition, or would it start a new war with Austria and Burgundy joining? I ask this because I want to force Aragon into the war not because I'm crazy for more enemies :rofl:

If the war leader changes to a non-coalition member then coalition members not already in the war don't get called. Members also don't get called if it will result in nations being allied in one war and foes in another.

If you start another war it will be exactly that, a different war, it will not add to an existing war. Any coalition members not at war with you would be dragged in if the nation you attack is part of the coalition against you barring a repeat of the war leader change/illegal wars scenario.

Aragon presumably was not called into your war due to not being eligible, otherwise the alliance would not still exist
