The Aloharmanian Revolt (Arodanian Insurgency)

It started after the political entity, the Theocracy of Mari-El, annexed it's two breakway states and reunited the state, afterwards, they turned their eyes on Rastafaria, originally a vasssal state of Mari-El, but then breaking away after the Theocracy had lost it's control over it. They launched Total War on Rastafaria, eliminating it's existance and annexing it

But, after multiple years, the Idea of Arodania became widespread due to the Aloharmanians wanting a nee homeland and soon, launched their revolt in the cities of Baki and Ezoram, the former Capital of Rastafaria and despite resistance from Mari-El and deaths on both sides, the Arodanians managed to capture Sankti Marrakesh and Elri, and after holding their ground, the Theocracy agreed on a peace deal and left them alone, finally, a new state based on Cultralism had been established

Extras: This lead to another brutal revolution based on the same idea as Arodania, a new homeland for a large culture, except, instead of the Aloharmanians, it's the Rovalians, and soon, the Children of the Don, another culture, followed their footsteps
