The Old Coalition, rarely called the Mandalorian League in reference to the signature of the agreement on the planet Mandalore, was a military alliance consisting of the armies of the Black Sun syndicate, Mercantile League, and the unified Mandalorian worlds. It was founded in 298 BBY after the Shadow Crisis and, taking on Mandalore the Inexorable as its sole leader, rose to prominence as a unifying government for the wounded, fragmented remains of Mandalorian Space. The League quickly allied with numerous criminal syndicates that had come under fire under the new Hutt-controlled Galactic government; the mounting threat of the Protectorate soon came to a head and the Coalition was plunged into conflict with the outbreak of the Tion-Corporate Uprising.
