The Four-Score War took place between 1E 2840 - 1E 2920 and was centered around the border regions of Morrowind, with the armies of the Reman Dynasty facing the Tribunal-led forces of the Dunmer. The war was initiated by Reman II after he had successfully taken over Black Marsh, Reman II died fighting the Dunmer in 1E 2843 and the war was then continued on by his successors Brazollus Dor and Reman III.
The war ended inconclusively when Emperor Reman III sacked the fortress of Black Gate and was assassinated by the Morag Tong. The throne passed to the Akaviri Potentate Versidue-Shaie, who suspended further attacks against Morrowind by signing the Cervant Truce with Vivec in order to solidify his power in the opening years of the Second Era.
