Well the Thalmor were organized a bit before the oblivion crisis, which would predate them before Jyggalag was "separated" from Sheogorath. I think the Thalmor are mentioned (not by name) by passing NPCs in Oblivion as a group of wizards banning together. They were already granted power by the Altmer government. So I'm not 100% if it all adds up to Jyggalag having a hand in it at all, to me it just sounds like a bunch of really powerful wizards with silver tounges who really took advantage of the chaos to further their own goals. Bravo to them.
