Your nations native population:

[Costa Luminosa]

The native people in Costa Luminosa are the Arabs. They currently constitute about 15% of the population and from 1900 to 1998 ruled the country as a dominant minority.

[Solomon Israel]

That really depends. On the one hand, most of the Arabs in Israel have been living in the region since the Islamic Conquests in the final centuries of the first millennium AD but on the other, the Jews had inhabited the land of Israel for far longer than the Arabs had.

[Rhodshaka]

The Zulu and Shona ethnic groups

[Estainia]

We are the natives overwhelmingly. The Alisonians and Darcsens have always been here and in both cases can trace their cultures back to the upper Stone Age. Estainians are more recent arrivals, appearing in the Copper Age, while the Gypsies are the newest arrivals from the Bronze Age forward, in any case we dominate our geographic area and excluding the Roman Domination, always have.

Sorry, but I thought I should just point out that "Gypsy" is a racist slur akin to the "n-word." Just for future reference.

If I had intended the Roma, I would have said Roma.

La Gitanos - A Hindustani language speaking people, the Gitanos or 'The Gypsies' are somewhat of a mystery. They are travelers, nomads and wanderers that appeared in Sotia sometime in the 6th century BC but are contested to be much much older than that. The term itself is said to mean 'The Travelers' in Ancient Alisonian, Gitanos refer to themselves in friendly company as the 'Sindhu' people. They have had no nation or empire known to other Imperials, and have instead likened to wandering through current nations as they rise and fall. The Sindhu people stood with the Darcsen in the Light Wars of mythology and even to the modern day, owing to their unwarranted and unfair reputation as liars and thieves, find comfort and shelter among their estranged brothers. The Sindhu worship a God known in the Empire in as Demetria, in Mahabharata she is known as Parvati and is worshiped almost exclusively among the Gypsies in the manner seen in the Empire. Ethnically, the Sindhu are as Indian as their language and God.

[Stormaen]

There was none. When it was discovered in the early 16th century, Stormaen was unpopulated.

[Nation of the Genuine Peoples]

Around 24,000 indigenous people reside in the Protected Zone; their endangered poopulation has meant that Embál government has made drastic measures to segregate them from the capital.

[Indonesia Merah]

The natives in the People's Republic of Indonesia Merah are the Austronesians who make up about 90% of total population.

[Soled]

The native Siberian Peoples here still thrive in the northern parts of the nation.òœó

[Omarios]

Bedouins have been living in Omarios for thousands of years.

[Amury]

Essentially, we are the native populations and we far outnumber any foreigners living here and continue to dominate Amury (as it should be).

[Thervingia]

The Goths and East Slavs are our native population. They compose about 85% of the population, the rest of which are Greeks, Baltics (mostly Latvians), and Turks.

[Nekronia]

Nekronia had its original population come from the Scandinavians during the Viking age. They were quite isolated for centuries, and are the native and original population. They remain the entirety of the population due to a no-immigration policy.

[Punkvania]

The native population before us was only teddy bears. We have found evidence over the centuries that ancient humans at one time inhabited the country, but it is theorized that they fed the bears drinks after midnight.

[Anollasia]

The Hellenistic Lyrians are believed to have lived in Anollasia 800-1400. However, due to their new discovery and limited evidence, we don't how or why they left before we came.

[Orveleca]

The vast majority of Orvelecans are Malagasy, the natives of Madagascar. They are descended from the offspring of Africans and Indians (the kind from India), meaning they are actually mixed race. The largest minority are French, making up 2% of the population.

[Dagnia]

Dagnians are the native population of Dagnia. The system was uninhabited and thought to be uninhabitable when first colonized.

[Yulis]

everyone?

[Greater Mackonia]

The Old Macks are the indigenous human population, they are distinguished by their completely white-silver hair, pale skin and golden-yellow eyes.

[The remulians]

remulians...that means us.

[Wardie land]

There are numerous natives of the Empire of Wardie land, they have been conquered in wars

Islanders:
The original inhabitants of the Home Islands archipelago, English settlers arrived in the 16th century and took over, as with all conquered peoples the Islanders have the status of second-class citizens in Wardie land, the settlers discovered that the Islanders had a particularly brutal method of execution, the victim would have each leg attached to a bent-over tree held down by rope, the ropes holding the trees down would then be cut and the trees would recoil, tearing the unfortunate victim to pieces, the pieces would then be left hanging from the trees, this particularly horrific execution was immediately banned as "inhumane", the settlers who were unlucky enough to witness such a horrible way to die were scarred by the brutality and horror of it, some almost for life, this was part of the reason why it was immediately banned, along with the mere concept of it.

A war broke out in 1749 between the descendants of the settlers and the Islanders, in which the Islanders were defeated, which culminated in the Sauva Massacre, in which 400 Islanders were executed by the Wardie land Imperial Army for high treason, the Firing Squad and the "Blowing from a gun" executions being the execution methods of choice at the Sauva Massacre, the Islanders accepted Wardie land rule over them, these days they are friendly with the White peoples of Wardie land, both the war and the massacre being largely forgotten, some Islanders serve in the military, as part of the Native Forces, they're led by a white officer. If any Islander steps out of line with a white person, the white person is usually quick to threaten them with a "Recreation of the Sauva Massacre" if they don't watch their mouth.

Some Islanders are part-white, these "Anglo-Islanders" have light brown skin, lighter than normal Islander skin, for the most part they're part English, since people of English descent make up the majority of Wardie land, the Anglo-Islanders are treated better than pure Islanders, the Anglo-Islanders are treated as first-class citizens, because of their white blood, despite being classed "Half-caste". The Half-caste Islanders get on better with the white rulers of Wardie land even better than the pure Islanders, because they're closely related to the white people of Wardie land.

The Islanders originally worshipped an avian humanoid called "Idrix", as well as a reptilian humanoid god called "Uzgekht", who the Islanders considered their "master", Uzgekht was the god of strength, war and sex, since he physical form was thought of as attractive by females.

Saqans:
Natives of Saqa Colony, a desert colony in the Western Colonies, the Saqans were conquered after the Wardie land-Saqan War of 1829, some Saqans fought in the Saqan Rebellion of 1933 and were defeated, the leaders of the rebels managed to escape, and in 1941 paid the Black Square mercenary to fight Wardie land, beginning the Mercenary War, Black Square were defeated and the leadership of Black Square and the Saqan rebels were killed after Imperial Desert Air Force bombers bombed Black Square's HQ, the Saqans these days bear little ill will towards their Wardie land rulers.

Other peoples are Earthlings of course, Venusians, Martians, the Soulless and Extraterrestrial peoples like the people of Pluto who brought their own religion to our culture. Native Mercurials, the Soulless, Venusians, Earthlings and Martians are also known as Intraterrestrial peoples.

[Everfrea]

The first humans to settle the forests of Everfrea were an extinct tribe of most likely African appearance, which could be the reason why the Witch Queen usually chooses to appear as an African woman. But they all died before the next wave of settlements reached the country.
