The Second Mandalorian War, more commonly known as the Sith-Mandalorian War to avoid confusion with the similarly name conflict, was an ongoing war between the Sith and the Mandalore Alliance, an assemblage of Mandalorians and their Jedi allies.
Two years after the end of the First Mandalorian War and the formation of the Mandalore Alliance, the Sith Empire destroyed the Tsad Station, which had been built as a symbol of the Alliance and a hub for both the Republic and Mandalorian Empire.
