Crimson League

The Crimson League is a political and economic bloc containing half of the Sunlit Worlds. It is a core member of the Concord of Reconciliation. Although once but one of Sanghelios' principal powers, the Crimson League has become known in the last millennia as the immediate political sphere of influence of Sanghelios itself. The League's name comes from the traditional color associated with several prominent Sanghelios houses and states, and recurs throughout Crimson League iconography in various forms. The member states of the Crimson League are often called the Crimson Realms.

History
Although the Crimson League has existed for thousands of years, it has undergone numerous reorganizations over the course of history, and there have been periods when the League has existed in name only.

Origins
The Crimson League was founded shortly before the War of Many Banners, as a defensive pact between several polities surrounding and including the Urs system; the war also saw the League's consolidation as a formidable power. The League would fight against several factions, though they would engage with the Thar'shi Sphere most often. Ironically, they would find themselves fighting a common enemy with the appearance of the San'Shyuum and the War of Beginnings. The war saw the Crimson League, the Thar'shi Sphere, and several other Sangheili polities forming a common front and normalized political dialog, which persisted into the Sangheili's governing structure in the early Covenant.

Under the Covenant
With the advent of the Covenant and its ministries, the mission of the League shifted. Due to this shift, a number of members divorced from it, forming their own factions. The early Covenant's governance was far more hands-off than in the later ages of the Consolidation Period, leaving the Crimson League and other Sangheili polities with considerable responsibility over their own governance up until the reforms of the First Illumination.

The Great Schism
The Great Schism saw the Crimson League retaining most of its historic members, although it became less significant as a political forum through the advent of the similarly-organized Concord of Reconciliation. Internal disagreements would persist in the League throughout the years of the Schism, even as the continuing war against the Loyalists kept them largely unified.

Tribulations and Blooding Years
As the years went by and treaties with the Jiralhanae mitigated the enduring Loyalist threat, the political and theological disagreements among Crimson League worlds widened into rifts for some members, and several member polities would go so far as to resign in protest. On the other hand, the League also gained members during this time through worlds which shared the Concord's unifying vision.

Governance and politics
In its modern form, the Crimson League acts as a free trade zone and handles certain external political affairs for members. It as well acts as a platform for such members to negotiate among each other over matters not covered by the Crimson League's mission. Previously, the League acted as a defensive coalition of its members, requiring members to come to aid one another in times of war and to adopt League wide materiel standards. The League's military acted as a major influence on the armed forces of the early Covenant, though the succeeding millennia of the alliance have seen influence flowing both ways.

Former

 * Subanese Council
 * Archkaidonship of Qikost
 * Sanghelios Plenary Council

Current

Military
As is typical of Sangheili-led armed forces, the Crimson League itself maintains only a small cadre of troops, with most of its military power coming from the member polities.

Historical
During the military alliance period of the Crimson League, it boasted a distinct style of starship design. The well known League ship 'Hraan Jalata was in this style.
