The Illini Republic is the name of a brigand group that inhabits the ruins of the University of Illinois at Urbana–Champaign. They fought for many years with the raider bands of Eureka for control over I-74 in central Illinois.

From 1995 to 2003, they fought constantly with Eureka, with both denying Illinois north of the I-74 to any more civilized parties.

In 2003, following the movement of the Quad Cities Alliance toward Eureka, and facing their own problems to the south with Vandalia and Kentucky, Illini sent an emissary to Eureka, asking for an alliance. The mission was successful, in no large part due to internal strife in Eureka.

Since then, the alliance between the two groups has kept central Illinois under their control. In that time frame, they have managed to deny patrols from both the Quad Cities and Kentucky-Virginia led American Alliance access or control of the area, inflicting heavy losses on those patrols which engaged them in combat. As a result, both have put immense restrictions on travel in and around the area. This, the East-West US-36 via Tuscola is the only road for Illinois states of the American Alliance to access the Wabash Union.

As of 2024, the Republic of Lincoln and Wabash Union has exerted significant pressure on the raiders of Illini, wresting control of the 1-57 and US-36 from it, effectively surrounding the rogue bands on three fronts. With most of the founding brigands dead and gone, the ravaged outposts inherited the contemporary Illini inherited is significantly weaker. The ability of the group to organize raids, much less successful The Illini still control most of the I-74 between Eureka and Illini, and with the surprising defeats of previous American Alliance attempts to quash the groups, the Illini are most likely here to stay. Only time will tell whether the group will continue to act with malice into their destruction, or if the group will gradually reform by economic necessity as the region slowly but surely becomes more densely populated again.
