Star League

In the fictional BattleTech universe, the Star League was an interstellar empire that united the various states of the Inner Sphere into a single alliance of nations.

First Star League
Its Member States include the five nations known today as the Successor States and the Terran Hegemony, a star empire centered around Terra. Eventually the states of the Periphery are forcibly integrated into the Star League and the number of Member States climbed to ten, the Federated Suns, the Lyran Commonwealth, the Free Worlds League, the Capellan Confederation, the Draconis Combine, the Taurian Concordat, the Magistracy of Canopus, and the Outworlds Alliance. Two nations were destroyed in the Fall of the Star League, the Terran Hegemony and the Rim Worlds Republic. House Cameron, the leaders of the Terran Hegemony, also acted as the leader of the Star League Council; they retained the title of First Lord of the Star League.

The Star League was disbanded when House Cameron was brutually executed by the leader of the Rim Worlds Republic, Stefan Amaris. Amaris executed the bloody coup and declared himself First Lord of the Star League. Commanding General Aleksandr Kerensky of the Star League Defense Force quickly moved to crush the Rim Worlds Republic, then advanced on the Terran Hegemony. The Amaris Civil War was fought with nuclear weapons and left billions dead in its wake. The Territorial States, as the Periphery nations were known, completed their secession bid, and each of the leaders of the five Great Houses returned to their respective capitals. In turn, they each declared themselves First Lord and fought a series of brutal conflicts known as the Succession Wars that were inconclusive.

The Second Star League
After the Clan invasion was halted in 3052 and following the Clan Jade Falcon Incursion of 3058, the nations of the Inner Sphere met on Tharkad to hold the Whitting Conference in 3058. At the conference, deciding to reform the Star League with the goal of ejecting the Clans from the Inner Sphere. They also elected Chancellor Sun-Tzu Liao of the Capellan Confederation as First Lord for the first three-year term. Succeeding in annihilating Clan Smoke Jaguar entirely in 3060, but the League soon fell prey to factional in-fighting. During his tenure as First Lord, Sun-Tzu used his position to place Star League Defense Force peacekeepers in the St. Ives Compact as a prelude to his invasion.

Coordinator Theodore Kurita of the Draconis Combine was elected in 3061. During his tenure, SLDF peacekeepers annexed the Lyons Thumb for the Draconis Combine after a purported assault by Lyran forces.Elected Prince-Regent Christian Mansdotter of the Free Rasalhague Republic was elected in 3064 and had a quiet term. Despite invasions of Star League member-states by both Clan Jade Falcon and Clan Ghost Bear, neither the Lyran Alliance nor Draconis Combine asked for assistance. The in-fighting and general apathy culminated in 3067 with a vote of no-confidence in the Star League that resulted in its second disbandment. This action would be the supposed reason of the eventual Word of Blake Jihad.
