I remember reading about the Argonians reclaiming some ancestral land from Morrowind, but after they reclaimed it on the way to pillaging the rest of Morrowind. They only managed to make it to half of Morrowind until House Redoran stopped them and thus projected themselves to be the formost of the Great Houses. After that Mournhold was in shambles and the capital was moved to Blacklight (the Redoran capital). House Telvanni was decimated (but not completely destroyed), House Dres had to have suffered heavy casualties due to their Argonian slave trade, House Indoril brought back the original Tribunal of Azura, Boethiah, and Mephala, and House Hllalu got it the worst. When the Empire pulled thier legions out during the Oblivion Crisis to defend Cyrodil instead of Morrowind, and then a couple decades later the Argonians invade, the general population's anger against the Empire was projected by the other houses onto House Hllalu (the royal House who had supported the Empire since Tiber Septim made Symmachus and Barenziah, of House Hllalu monarchs over Morrowind). After this House Hllalu's Great House status was revoked and House Sadras was upgraded to Great House status.

In the Fourth Era the Ministry of Truth also crashed into the city of Vivec (between the Oblivion Crisis and the Argonian Invasion) destroying the city and causing Red Mountain to erupt (The Red Year). The Morag Tong would have to disband for a while until Morrowind was repaired, though they also seem to be on Solsthiem. This also brings up another point, one of the High Kings of Skyrim also gave Solstheim to Morrowind after the Red Year. Lastly House Hllalu has been up to plans and plots to reclaim their lost power.
