All we know is the period, not specific time. Its easier to say why it disbanded. Thanks to the oblivion crisis, manimarcos actions during it and the ban on necromancy the schoolnof conjuration was distrusted. This lead to rifts in the guild. One one side there were those who thought conjuration should be banned, and those who thought its ok. Another reason is that it had become all about politics and not learning about magic. It ended up splitting into the Synod (anti-conjuration) and College of Whispers (pro-conjuration) also, the colleg of winterhold has nothing to do with the mages guild
