Trinity Alliance
Organization Profile
FoundedAugust 3058


The Trinity Alliance is a mutual protection and nonaggression pact between the Capellan Confederation, the Taurian Concordat, and the Magistracy of Canopus, signed in August of 3058. It ended soon after 3067 when the Taurian Concordat withdrew and began accepting Word of Blake aid against the Federated Suns.

On the surface, the alliance was proposed by Chancellor Sun-Tzu Liao as a means to advance the technology and internal capabilities of both the Concordat and Magistracy. Beneath the surface, the Alliance was orchestrated as a power-play by Chancellor Sun-Tzu to tip the balance of power within the Inner Sphere in his favor:

  • Mutual defense of the three realms allowed the Confederation to increase the size of its military, in particular by utilizing Canopian troops during the Capellan-St. Ives War.
  • A strengthened Taurian Concordat and Magistracy of Canopus would be a thorn in the sides of the Federated Suns and Free Worlds League, respectively.
  • And within the Second Star League, the new voting block of three realms eased the possibility of passing motions favoring Chancellor Sun-Tzu's policies.

However, there were some drawbacks for the Capellan Confederation. With the signing of the Alliance, it became impossible for Sun-Tzu to play the two Periphery powers against each other. He also had to listen to their concerns and address them if he wished to keep their support.[1] The technology transferred from the Confederation to the Magistracy and Concordat allowed the factory world of Detroit to be developed in a short period of time.[2]

Interestingly, a similar scheme was proposed by a previous Capellan Chancellor. Chancellor Arden Baxter of the nascent Capellan Confederation proposed the "Thousand-World Coalition" in 2422. However, the initial proposal was rejected by Regent-Protector Admiral Sigur Fonn of the Taurian Concordat.[3] [4]

Negotiations for the Trinity Alliance began in 3058.[5] Some Magistracy forces were used in Operation BULLDOG, and the Magestrix lost her daughter, Danai Centrella during the Great Refusal. This led to several Magistracy news sources questioning the value of the Trinity Alliance.[6]

Though a full partner in 3062 the Taurian Concordat actually delayed participation per the wishes of Protector Jeffrey Calderon. It wasn't until he was killed in 3061 that the Concordat joined as a full member.[7] The Taurian Defense Force was quickly tapped to reinforce the CCAF.[8]
