Yes. They did invade Tamriel from the north and due to his, it's what basically formed the Ebonheart Pact. They were driven out from Tamriel in the region of Stonefalls, in Morrowind, where they met their end, it's explained in a quest in ESO and if I'm not mistaken, Vivec had helped the Pact to drive out the Akavirians in the final battle.
