Overview of Stoinian Terran Ethnicities and  General Culture
The Stoinian Star Kingdom was founded on the principle to preserve Terran cultures and ethnicities. The state therefor has made programs throughout the nation's expansion to dedicate planets to preserve these cultures. The Stoinians have taken great pride in their Terran traditions, but cultures do evolve and some Stoinians have even tried to reinstate old Terran cultures of old. These cultures had to adapt to the larger Stoinian culture (called Stoinism), survival and frontier spirit. On large metropolitan planets such as sector capitals, some cultures have collided together and formed new ones. The original Terran cultures have also been subject to a few rebranding and have since evolved to become different from their old Terran counterparts. There is a distinction between the cultures evolved directly from Terra (called as Terran) and those who were the result of a mixture of multiple Terran cultures (called Neo-Terran).
Terran ethnicities are often rebranded by the larger Star Kingdom after their primary planet which was designated to preserve that culture and Stoinians at large will refer to their rebranded names. Though exceptions exist as some ethnicities are named after their nicknames or even skin colour. Despite this, there is no racial stigma between the ethnicities, though on planets where a Terran culture has a strong presence there may be some frictions as those families expect their members to continue their lineage. This has devolved over the years and knew its height during Traian's rule.
Despite this, all Stoinians are required to learn English as it serves as the common tongue in the Star Kingdom and all government operations are done in English. This may differ on planetary governments though.

Neo-Terran Ethnicities and Subcultures:
Louisianan:
Lousiana was one of the main planets colonized by the Stoinians and from the start it was a melting pot of all Terran cultures. Louisianans commonly have brown hair and eyes. They also tend to be taller then most Stoinians and have a sturdier build. Their skin also tends to be slightly weathered from Louisiana's rain hurricanes. They also tend to be excellent mechanics as street racing is a prominent aspect on Louisiana and they modify their cars themselves. Louisianan culture is predominantly influenced by Neerian culture and form a large proportion of members within the ranks of the military and are known to be noise makers with blunt opinions.

Reachian:
Although the planet Reach fell during the Velutarian War, its culture still lives on. The original settlers were of Neerian and Sinaian origin and have mixed their culture. Though Neerians are mostly Protestants, Reachians are predominantly Stoinian Orthodox like the Sinaians. Compared to both cultures, Reachians tend to be less blunt and more reserved. They also tend to be more open than most Stoinians and quicker to take the blame in day to day problems.

Kuatisian:
Kuatisian is a result from the mixture of Nemtian and Neerian colonists on Kuatis. Kuatisians have become synonymous with their Drive Yards and their culture reflects it. Like the Louisianans, there are no clear ethnic distinctions as there is a wide variety within the Kuatisians. They have grown a hardworking culture however, often using new and unorthodox methods to apply to their problems. They also have likely grown up in some capacity on the Drive Yards Ring and are often seen on other space habitats as primary inhabitants as they have grown accustomed to the setting.

Nova Romans:
Nova Romans are a result of colonists reviving ancient Roman culture. Although Nova Romans are perceived to be white with dark hair, members with diverging looks are also considered Nova Romans as long as they uphold the Nova Roman culture. Though their origins will likely be seen in their cognomen such can be seen in the name Spurius Nigidius Niger. Niger signifies that this man has a black skin colour, though this was often seen as negative in previous times, Stoinians have learned to dismiss such rhetoric and often take pride in it. It should also be stated that Nova Roman culture is also more blunt than other Terran cultures. People will give descriptive cognomens which can last well into ten generations despite that description being lost by then. In Niger's case this is due the case of a majority white populace on Italia and have reaffirmed the man's uniqueness compared to the rest, albeit it through his skin colour. This doesn't mean that he is viewed as lesser, on the contrary the Nova Romans are highly utilitarian and highly value inner strength.
What makes Nova Romans special is their eccentric rituals and customs (festivals, sexual openness, drunkenness festivals, ...) and their renewed religion of the Unconquered Sun: Deus Sol Invictus. Most other Stoinians would see them as decadent, though they make up for it with their lust for combat, especially melee combat. They have also grown fond of their fashion and traditions and will not hesitate to explain it to anyone, albeit with a tone of superiority. Another detail is that they speak a dialect of Latin, thus resurrecting the language from the dead.

Neo-Byzantine:
Like the Nova Romans, the Neo-Byzantines have revived early Byzantine culture of old. They are somewhat similar to the Nova Romans, but have grown to be devout followers of Stoinian Orthodoxy. They refrain from the Nova Roman eccentricities as a reflection of their strong belief in Stoinian Orthodoxy. They also have a tendency to preach their religiosity and entangling people in theological debates. They often are educated in both Latin and Greek. 

Elysian:
While Elysian is a direct continuation of what remained of French culture, it has taken some Sinaian elements as Sianaians took over their culture to help protect the culture. This has resulted in some customs being adopted into the French dominated culture. Elysians tend to be more progressive and reflect it most commonly in their modern architecture which boast technological advancement. They also do have a reputation as heavy eaters and it isn't uncommon to see Elysian eat a small fourth meal later into the night. 

Rhodesian:
Rhodesia attracted many Anglican farmers, but they eventually changed over the centuries. Their accent changed over time and even their skin got a darker tone. They also adopted Stoinian Orthodoxy as their main religion and have spread since on many farmer worlds. Like the Boers, they are renowned farmers and their culture has many festivals to reflect it. They also tend to live on more rural worlds with an advanced ecosystems which they most likely will try to tame. While the Boers were the primary frontier pioneers in early days of the Kingdom, it's the Rhodesians who have taken their place as master farmers in the Star Kingdom as they spread more widely than the Boers.

Skandian:
Because colonists of Scandinavian origin were sparse, they grouped together to form a large Scandinavian culture mixing all of them into one culture. For this reasons, the other Stoinian ethnicities called them by their abbreviated name: Skandians. Skandians tend to be paler, but not as pale as Anglicans. They often inhabit planets with higher gravity and their stature reflects it as they are the tallest ethnicity and have a bulkier form. Both sexes tend to bear longer hear and braiding it is seen as acceptable by both sexes. All in all, they tend to differ between biological differences in their communities.

Stoinism:
Stoinism is what the Stoinians call the larger Stoinian culture which encapsulates all Terran ethnicities into one larger star nation. The primary belief of Stoinism is the preservation of Terran culture and to protect whilest also cherishing it. Stoinism stands for the survival of a state where all Terran cultures can live together in one state. No repressive actions against Terran cultures can be taken and this also reflects in their approach to other Terran star nations. Often they will accept other Terran culture and show interest in a mutual protection act or at the very least a statement of non-aggression. A strong aspect is that Stoinians must die trying to protect their culture and way of living. To ensure this on a large and efficient scale, Stoinians see no problem in assigning authoritative measures during times of crises like Regent MacArthur's rule, the monarchy and the subservient aristocracy. This is to show that Stoinians have authoritarian tendencies even if they are a staunch believer in democracy. Order is highly respected in Stoinian society as a tool for authority and seen as necessary to ensure the survival of the Terran species.
This is however beginning to be challenged as more and more xeno species join the star nation. Time will tell if this remains exclusive to Terran culture.

Terra Firma:
Terra Firma is the Latin motto which is used to describe the staunch believe to protect and cherish their Terran cultures. It summarizes their view on their culture and traditions which they view as standing firmly in a sea of stars filled with darkness by barbarian xeno races. This belief has been firmly held throughout the expansion period of the Star Kingdom when they were forced to fight against non-cooperative xeno species.

New Stoinian Order:
The New Stoinian Order is the firm believe that Stoinia should be an active player in astropolitics and show the light in the sea of darkness. This is often coupled with Terran superiority and military prowess. It's the belief of the Stoinian state to bring order to the galaxy through whatever means necessary. Stoinian factions still dispute on how this must be achieved and a highly debated topic in political circles. Members, like the King, prefer an indirect method and wish to achieve it through economic warfare and make other star nations economically dependant of the Star Kingdom, while members, such as the Traditional Party of Colonial Empowerment, wish for a more direct military approach with the subjugation of other star nations.

Stoinian Spirit and Honour:
While the Stoinians seek to bring order to the galaxy, they have a code of honour on how to achieve it. This code of honour is to instil the Stoinian Spirit in every Stoinian. The Stoinian Spirit is the fiery spirit every Stoinian is supposed to have and the embodiment of Stoinian essence. This often takes form in a readiness to fight for Stoinia and protect one's way of life. During peacetime, it's custom to follow this way of life to its fullest and traditions have become engrained in the bones of the Stoinians. 
Honour is also present in Stoinian society and duelling is often used to settle matters where honour is concerned. It should be noted that melee combat is seen as the more honourable way of duelling as it 

Peace through Arms:
Stoinian society has grown cynical over its history when it comes to contact with xeno nations. The state therefor allows considerable gun property for self defence and other weaponry as well. This is highly regulated and no Stoinian civilian may have plasma weaponry, unless for extreme cases such as dangerous planetary wildlife. Stoinians believe that by arming themselves, they will ensure peace in their day to day lives. Over time, it has become more and more discreet. Though open carriage laws exist, Stoinian society has come to a consensus that there's no need to carry such weapons in an orderly society. Mainly they keep they weapons at home as a last resort for an invasion and protection of their own property.
Stoinian Police as a result has also become more militarized to ensure this order. Many Stoinians agree with this stance and view it as a way for the state to protect them without them having the need to do so. Though the Stoinian Star Kingdom has no intention to circumvent the rights of its citizens to do so.

Backbone of Mankind:
To ensure the survival of the Mankind, it became abundantly clear to the early Stoinian colonists that they had to reproduce at a higher rate than was normal on old Terra. It the early days it was common to have 10 children, this put a great deal of stress on the woman's body. However, over time the Stoinians have perfected preparations and Stoinian women are required to be fit and engage in special exercises to enhance the muscles needed when giving birth. Stoinian women are highly regarded and respected, often called the backbone of Mankind. Without them, there wouldn't be a Stoinia. Nowadays Stoinian families mostly consist of just 6 children and has steadily decreased in number of the Star Kingdom's existence. 
This view on women has lead that crimes against women are seen as much graver and rapists are seen as the absolute scum and likely will be killed before their execution by law. However, if a woman is to lie about such a case, she will be shunned from society and will struggle to regain her life.

Frontier Culture:
On the outer colonies of the Stoinian Star Kingdom, but also on newly colonized worlds, there is the Frontier Culture. This culture aims to form a planet's own culture and traditions. Most often than not it will be inhabited by many ethnicities which come together and sometimes even blend to form a new. Though this terminology is fairly vague, often farmers and frontier jobs are highly associated with it. A flinch of the unknown is ever present and these Stoinians aren't scared to change and adapt their ways to new obstacles. Another aspect that is omnipresent in Frontier culture, is self-sustainability. This is reflected in the pioneer spirit of the Stoinians on the outer colonies as many go into the wild and tame it to sustain themselves. Gun carriage is common and abundant on these worlds due to the wild nature of their planets.

Great Hunt:
The Great Hunt is a yearly televised hunt where the most elite hunter of the Star Kingdom go into the Mardakii Reservation on Stoinia. This Great Hunt is a yearly reminder of the cruelty of the War at Home and an atonement for the Mardakii as a species for their crimes during. It's seen as Terran superiority and triumph throughout the Stoinian society, though some elements have started to question the necessity of it. Nonetheless it remains a very popular event in Stoinian society and will take pride in it more often than not.
Commodities from the Great Hunt are highly treasured. These range to claws and hides to meat which require reservations for a month in advance and often end up in a bidding war. The Great Hunters are also highly regarded and become media personalities all over Stoinia. It is also customary that a gift is given to the Royal family as a thanking for its leadership during the War at Home.
