The original inhabitants of Artania, before the arrival of the Superseleyan people, would have been, essentially, Bantu. An Ikradoni River Valley civilisation similar to the Harappans or Predynastic Egyptians would have developed. The combination of the arrival of the Superseleyans and diseases, internal issues, and climatic factors, however, would lead to its ‘collapse’. Most of Artania’s inhabitants would take up nomadic pastoralist lifestyles like the Superseleyans and be absorbed by them.
In Ikradon, however, although the native inhabitants would adopt the new way of life, the higher population would lead to more mestizo-esque peoples (represented by African-Americans) in combination with less mixed peoples (similar to how you still have the Maya in Mexico today) (represented by Africans). Some might adopt Dundorfic languages, explaining Ichredone and the sort, some might keep their original languages. This would also explain the Black Alorians and Rutanians.
Cut to 2034, when Ikradon’s game history begins.
The groups speaking their native languages are marginalised and unrepresented in the legislature. The mestizo-esque Anglophones are in the majority and firmly in power. Until the thirty-seventh century when, leading a cultural and linguistic revival, a tribal confederation dominated by the Ibutho and named for them takes power. Most of the mestizo population assimilates, actually having voted for this like a bunch of cottagecore teenagers because social alienation sucks, and those that don’t leave for Rutania (most of them will be back later).
Now I’ll quote from the Wiki.
The Golden Age was ended in the mid 3800s by the Mopoho Interregnum during which a foreign-backed insurrectionist force deposed the reclusive King Bathandwa, launching the then-prosperous country into 150 years of regression. Alternating military and Metzist governments lead the country through severe successive economic depressions and a radical dismantling of Golden Age values.
Bathandwa's nephew, King Saksoure III of Cobura, attempted a renaissance for much of the 40th century. The revitalization effort, however, proved too great an administrative hurdle for the foreign king, who was himself deposed from the Ibutho throne in 3971.
Large-scale emigration, already apace during the Mopoho Interregnum, increased torrentially over the next half century's repetition of foreign-backed and Metzist policies, leaving the country at one quarter it's usual population by the 4020s. A foreign-backed government had planned the dismantlement of Ibutho throughout the 4020s before that government itself collapsed several years later. In 4039, President Ihejirika was elected to lead the few remaining citizens of Ibutho, whose population had by then dwindled to a mere 2 million.
Hawu Mumenhes was founded in 4043 based on a plan by Fourth Week Group, a transcontinental members-only association of Esinsundu executives who sought to build a new country in the former territory of Ibutho after mass depopulation in that country. Fourth Week Group aimed to create a country that could guarantee freedom, prosperity, and security for its citizens and the world. In 4039, Fourth Week Group tasked Esinsundu-Rutanian insurance executive Hermelinda Shelby with the creation of an Ibutho political party to implement the Group's objectives.
The territory that became Hawu Mumenhes was repopulated primarily through hiring and salary incentives offered by Fourth Week Group and their extensive network of business colleagues and controlled companies who partnered together to redesign and reconstruct the territory's infrastructure and economy. As a result of this unique peopling, Hawu tend to be business minded, fiercely capitalist, and part of the professional class. Fourth Week Group members were in the main patriotic and nationalist. They therefore focused their recruitment on Esinsundu countries, provinces, and neighborhoods when hiring for the new Hawu economy. Many of the targeted Esinsundu jurisdictions had faced down gross and/or repeated war crimes, barbarism, torture, and even genocide committed by various Artanian, Gao-Showan, and Majatran culprits. This historical memory has contributed to widespread sentiments of militarism, nationalism, and interventionism among the Hawu, especially when Ezinsundu are involved or Esinsundu interests are at stake.
Ibutho's exiled royal family and many nobles settled in Cobura, which shared a 200-year diplomatic relationship with Ibutho due to royal marriage ties and closely-related religions. Following the Hawu Mumenhes Constitutional Convention, the Ibutho royal family returned to their land of origin to reign in the new country's democratic monarchy. During their long stay abroad, the royals had experienced significant Coburization, including adopting the ancient religion, fashion, and language of their adoptive country. The royals brought that acculturation with them when returning to East Artania and inspired a similar Coburist zeal amongst their new Hawu countrymen. Due to this influence, Hawu's language, religion, and fashion are distinctly Irkawan and Domalen in character, and Hawu architecture and planning were deliberately designed to be neo-Irkawan with a futurist twist.
No, I’m not going to bother with rationalising “King Arab Doge”.
