The Second Treaty of Csilla was a peace treaty signed by the Galactic Alliance and the Galactic Empire in 551 BBY. After the first Treaty of Csilla, which established limitations on military use after the peaceful dissolution of the Galactic Federation Triumvirate, the Alliance and the Empire realized that any attempts they made to evolve militarily could create suspicion and mistrust on the part of the other government, threatening centuries of lasting peace. The second treaty, again hosted by the Chiss Ascendancy, sought to rectify those concerns.
