These boundaries will determine who is and isn’t a member of the nation and who can become a representative or vote in national elections. ## Design principles for ancestral boundaries Ancestral boundaries need to be pragmatic, administratively workable and not excessively strict. If the boundaries are too rigid, they can create statelessness and unnecessary exclusion. If they are too loose, they may fail to preserve the continuity and self-determination of the long-established ancestral group. A workable system therefore needs to balance group preservation with legal stability, fairness and practical implementation. * **Avoid statelessness** — No person should be left without a country of legal belonging. During any transition, people should retain legal status until another citizenship or secure status is available. * **Avoid unrealistic ancestral purity standards** — Boundaries should not require total ancestral purity. They should allow for mixed ancestry, uncertain records and historical population mixture. * **Protect ancestral continuity** — Boundaries should be strong enough to preserve the long-established ancestral group, its identity and its continuity across generations. * **Protect political self-determination** — Distinct ancestral groups should have meaningful ways to govern themselves where there is clear collective support for doing so. * **Separate citizenship from political membership** — Citizenship, voting rights and representation rights may use different thresholds. Citizenship can be broader to avoid statelessness, while political membership can be stricter if needed. * **Use proportional restrictions** — Restrictions should be no stricter than necessary for the goal being protected. Different rules may be appropriate for citizenship, voting, representation and migration policy. * **Balance national and local autonomy** — National government should not control decisions better handled locally or regionally. Local autonomy is especially important where some citizens have limited national political influence. * **Use clear and workable rules** — The system should clearly define ancestral ties, thresholds, evidence standards, mixed ancestry cases and dispute procedures. * **Use reliable evidence** — Decisions should be based on evidence that is accurate enough, reviewable and open to challenge. Records and genetic testing should be treated as evidence with limitations, not as perfect proof. * **Provide appeals and due process** — People should be able to challenge exclusion, submit additional evidence, request retesting and receive independent review. * **Protect privacy and genetic data** — If genetic testing is used, there should be clear and transparent rules on data collection, storage, access, retention, deletion and secondary use. * **Maintain stability across generations** — Boundary rules should not change constantly. People should be able to understand and rely on their citizenship and political status over time. * **Handle transitions cautiously** — Existing citizens and long-term residents should not be abruptly stripped of status. Any transition should include clear rules, timelines, appeals and safeguards against statelessness. ## Future civic societies and stricter ancestral boundaries In the future, new societies may be created on an explicitly civic nationalist or cultural nationalist basis from the beginning. These societies may be more open to fluid identity, mixed ancestry and voluntary political membership. If such societies became widely available, they could change the global landscape of citizenship by giving people more options for national belonging regardless of ancestral background. In that context, stricter ancestral requirements in older, well-established ancestral nation-states might become more workable, because individuals excluded from one ancestral system would have alternative civic societies available to join. However, in the short term, ancestral nationalist systems would likely need to be more pragmatic and inclusive. Without widely available alternatives, overly strict ancestral boundaries could violate the principles of avoiding statelessness, maintaining legal stability and handling transitions fairly. ## **Problems with ancestral purity** Ancestral purity means requiring a person to have complete or near-complete ancestry from the long-established ancestral population in order to qualify for citizenship, voting rights or representation rights. At a national level, this is usually not a pragmatic boundary standard. The first problem is that most historical populations have some degree of mixture. Migration, intermarriage, border changes, adoption, disputed parentage and incomplete records make it difficult to establish perfect ancestral continuity for every individual. Even where a person has strong ancestral ties to the national group, a strict purity requirement could exclude them because of one ancestor from outside the group. For example, if a person has eight great-grandparents and seven of them come from the long-established ancestral population, that person may have roughly 87.5% ancestry from that group. A purity requirement would still exclude them, despite the fact that the large majority of their ancestry comes from the national population. This exclusion would also continue across future generations, because their descendants could never return to a condition of total ancestral purity. A purity standard could produce several practical problems: * Excluding people with strong ancestral ties * Creating statelessness if no other country recognises the person as belonging there * Makes citizenship dependent on very small ancestral differences * Creates a system that can appear arbitrary or excessively punitive This does not mean that ancestral boundaries must be extremely loose. It means that total purity is usually too strict to function as a national rule. A more workable system would use thresholds that recognise sufficient ancestral connection without requiring complete shared ancestry from one particular ancestral group. Smaller voluntary communities may choose stricter membership standards for themselves, but national citizenship and political membership boundaries need to be more pragmatic. ## **Risks of very low ancestral thresholds** Very low ancestral thresholds can create the opposite problem to ancestral purity. While strict purity standards may exclude too many people, very low thresholds may include people whose connection to the long-established ancestral population is minimal. If the threshold is too low, the boundary may no longer serve the purpose it was created for. This matters because ancestral nationalism is intended to protect the continuity, identity and self-determination of a distinct ancestral group. If people with only very weak ancestral ties are treated exactly the same as people with deep ancestral continuity, the system may become less effective at preserving the political self-determination of the long-established group. The issue is especially relevant for political membership. Citizenship gives a person legal belonging, access to state protection and a recognised national home. Voting rights and representation rights, however, determine who can influence the future direction of the state. These powers affect migration policy, citizenship rules, education, constitutional identity, resource allocation and long-term demographic policy. A very low threshold can therefore create several risks: * It may weaken the connection between ancestry-based membership and group continuity * It may allow people with only minimal ancestral ties to influence decisions about the future of the ancestral group * It may reduce the ability of the long-established population to preserve political self-determination This does not mean that people with mixed or weaker ancestral ties should automatically be treated as disloyal or hostile to the ancestral group. Individuals can have strong cultural, familial and personal commitments regardless of ancestry percentage. The issue is not individual character, but the institutional question of whether a very low threshold can reliably preserve the political self-determination of the long-established ancestral population over time. One way to manage this problem is to use different thresholds for different kinds of membership. Citizenship could use a broader threshold to avoid statelessness, while voting rights, representation rights or specific decisions about migration and naturalisation could use stricter requirements. Another approach is to increase local and regional autonomy so that different communities can make more decisions for themselves without reliance on a more rigid national governance system. The central design problem is therefore balance. A threshold that is too strict can create exclusion and statelessness. A threshold that is too loose can fail to protect ancestral continuity. A workable boundary needs to avoid both extremes. ## **Absolute versus proportional ancestral ties** Ancestral thresholds can be defined in two main ways: absolute thresholds and proportional thresholds. An absolute threshold requires a person to meet a fixed percentage of ancestry from the national group. For example, a 50% threshold would require at least half of a person’s ancestry to be tied to the long-established ancestral population. This approach is clearer and simpler because it only asks whether the individual has reached a defined level of connection to the national group itself. A proportional threshold works differently. Instead of requiring a fixed percentage, it asks whether the national group is the person’s largest single ancestral tie. For example, a person with 40% ancestry from Group A, 30% from Group B and 30% from Group C would be proportionally most tied to Group A, even though most of their total ancestry is tied to other groups combined. The strength of an absolute threshold is that it is easier to understand, easier to administer and more directly connected to the goal of ensuring a substantial ancestral link to the national population. It can rely mainly on the quality of the nation’s own reference panels, historical records and verification systems. This makes it more practical for a state to implement, especially during a transition period where the administrative system is still being developed. The weakness of an absolute threshold is that it can exclude mixed-ancestry people who have no stronger ancestral connection elsewhere. For example, someone may have 40% ancestry from one national group and smaller percentages from several other groups. If the citizenship threshold were set at 50%, that person would fail the absolute threshold even though the national group may still be their strongest ancestral connection. This creates a potential statelessness problem if no other country recognises them as a member. The strength of a proportional threshold is that it is more flexible for mixed-ancestry cases. It can help identify the ancestral group to which a person is most strongly connected relative to their other ancestry. This may be useful for citizenship decisions where the aim is to ensure that every person has at least one recognised national home. The weakness of a proportional threshold is that it is more difficult to administer. To apply it reliably, a state would need accurate genetic reference panels, records and ancestry-comparison systems not only for its own population, but also for many other populations across the world. Without strong external reference data, it may be difficult to determine whether a person is genuinely proportionally more connected to the national group than to any other group. A proportional system also creates cases where someone qualifies because their largest single ancestry is tied to the national group, even though most of their ancestry is from other groups in combination. For these reasons, an absolute approach may be the more pragmatic starting point. It is simpler, more transparent and less dependent on the quality of other countries’ records or genetic reference panels. A state could use an absolute threshold for both citizenship and political membership, while keeping safeguards in place that prevent people from becoming stateless. ## **Different boundary requirements for citizenship, voting rights and representation rights** Citizenship, voting rights and representation rights do not necessarily need to use the same ancestral boundary. These three categories represent different levels of membership in a nation-state, so an ancestral nationalist system could apply different standards to each of them. Citizenship is primarily a form of legal membership. It gives a person a recognised national status, access to public services, legal protection, residence rights and a secure place of belonging. Because citizenship is closely connected to avoiding statelessness, it may be reasonable for the citizenship boundary to be broader and more inclusive than the boundary for political membership. Voting rights and representation rights are different because they determine who has direct influence over the political direction of the state. Voting affects government formation, lawmaking, migration policy, citizenship rules, resource allocation and constitutional identity. Representation rights go even further because they determine who can hold political office and act on behalf of the nation. For this reason, an ancestral nationalist system may treat voting and representation as a higher level of political membership rather than simply as automatic consequences of legal citizenship. The argument for separating these categories is that a person may have enough ancestral connection to receive citizenship and avoid statelessness, while not having enough ancestral connection to participate fully in decisions that affect the long-term continuity of the ancestral group. This distinction could allow the state to remain inclusive enough to provide legal belonging, while still preserving stronger political self-determination for the long-established ancestral population. However, separating citizenship from political membership creates serious design challenges. If some citizens have legal membership but limited national political influence, then the national government should not have excessive control over every part of their lives. Local and regional autonomy becomes more important in this kind of system, because it gives people more influence over the decisions that directly affect their communities. Strong legal protections, due process, appeals and clearly defined rights would also be necessary to prevent the system from becoming arbitrary or unstable. A possible structure would therefore be to use a broader boundary for citizenship, a stricter boundary for national voting and representation rights and stronger local and regional autonomy as a safeguard. Another option would be to allow broader voting rights in these local and regional areas, but apply stricter ancestral requirements only to specific decisions that directly affect migration, naturalisation, citizenship rules or the long-term demographic character of the broader nation-state. The central design question is how much political influence should be attached to legal citizenship. A single boundary is simpler and more equal between citizens, but it may provide weaker protection for ancestral self-determination. Different boundaries are more targeted, but they increase complexity and create a stronger need for safeguards, local autonomy and clear legal limits on national power. ## **Suggested ancestral boundary for citizenship** The simplest citizenship boundary in an ancestral nationalist system would be to include anyone who has a proven ancestral tie to the long-established ancestral population. This would mean that any amount of verified ancestral connection above zero could be enough to qualify for legal citizenship, especially during a transition from a civic nationalist system to an ancestral nationalist one. The main advantage of this approach is that it helps avoid statelessness. If an ancestral nationalist model were adopted globally, each person would need to have at least one recognised national home. A broad citizenship threshold makes this easier because it reduces the chance that mixed-ancestry individuals are rejected by every country. It also creates a more cautious and stable transition by avoiding abrupt removal of legal status from people who have some genuine ancestral connection to the country. A broad citizenship boundary does not mean that all citizens must automatically receive the same level of political membership. Citizenship can be treated as the legal layer of belonging, while voting rights and representation rights can be handled separately if the system wants stronger protections for political self-determination. This allows citizenship to remain inclusive enough to prevent statelessness, while leaving open the possibility of stricter rules for national political power. A secondary requirement could be that the person has a parent with citizenship or a sufficient level of historical rootedness in the country. This requirement could help prevent situations where people claim citizenship in countries where they have only a very distant or weak ancestral connection, especially where similar ancestral groups exist across multiple countries. For example, a person with ancestry connected to Britain but whose family has been rooted for generations in Australia may raise questions about which country should be treated as their primary ancestral home. Each country would need clear rules for handling these kinds of overlapping ancestral claims. Mixed-ancestry cases would need to be handled carefully. Someone may have weak ancestral ties to one country but stronger ties elsewhere. In these cases, the system could allow the person to retain citizenship in their current country unless another country clearly recognises them as having a stronger ancestral claim. This would prevent people from being left without a legal national home while still allowing long-term citizenship rules to become more precise over time. There may also be people who are citizens under an older civic nationalist system but who do not have provable ancestral ties to the long-established ancestral group. Some may also lack clear evidence linking them to another country. This could happen because of missing records, incomplete genetic reference panels, adoption, historical displacement or lack of available data. In these situations, citizenship should not be revoked unless there is a clear alternative citizenship or secure legal status available. A temporary or transitional citizenship category could be used while evidence is reviewed, but the person should not be made stateless. If a person with very weak ancestral ties commits a serious crime, some may argue that denaturalisation should be possible. Denaturalisation should not be used arbitrarily, should require due process and should only be considered where another country clearly recognises the person as a citizen or rightful national member. Otherwise, it would conflict with the principle of avoiding statelessness. The recommended citizenship boundary is therefore broad and pragmatic. Anyone with a verified ancestral tie could qualify for citizenship, especially during the transitional period. Additional rules around parental citizenship, historical rootedness and stronger ancestral ties elsewhere could be used to clarify edge cases. The main priority should be to ensure that every person has a secure legal status while the system develops more accurate evidence and better administrative processes. ## **Suggested ancestral boundary for political membership** Political membership refers to the right to participate in national self-government through voting, holding office or making decisions that shape the long-term direction of the state. In an ancestral nationalist system, political membership may be treated differently from citizenship because it has a more direct effect on the self-determination of the long-established ancestral population. There are two main options. The first is a simple model where everyone with citizenship also receives full voting rights and representation rights. This approach is easier to understand, easier to administer and avoids creating different classes of citizens. It would be the more inclusive option and would reduce disputes over political exclusion. However, it may provide weaker protection for the long-established ancestral group if citizenship is granted to anyone with even a very small ancestral tie. The second option is a stricter model where political membership requires a higher level of shared ancestry. A possible threshold would be 50% or more shared ancestry with the long-established ancestral population. The reasoning behind this threshold is that someone who is at least half ancestrally tied to the national group has a substantial connection to that group and cannot be majority tied to another single ancestral population at the same time. A 50% threshold is also more pragmatic than a threshold that is above 50%, because a person with exactly half of their ancestry from the national group would otherwise be excluded despite having a very substantial connection. The strongest argument for a 50% political membership threshold is that political power determines the future of the nation-state. Voting rights and representation rights influence migration policy, citizenship law, constitutional identity, education, resource distribution and foreign policy. If the purpose of ancestral nationalism is to preserve the continuity and self-determination of the long-established ancestral group, then the boundary for political membership may need to be stricter than the boundary for legal citizenship. However, this approach has a drawback. It means that some citizens may have legal membership but limited national political influence. This could create resentment, legitimacy problems and a sense of unequal citizenship. The stricter the political boundary becomes, the more important it is to limit the power of the national government and increase local or regional autonomy. People who do not qualify for full national political membership can still have meaningful influence over local decisions, public services, community rules and the institutions that directly affect their daily lives. Another option would be to apply stricter ancestral requirements only to specific categories of political decision-making. For example, all citizens might vote in ordinary elections, but only citizens who meet a higher ancestral threshold could vote on migration policy, naturalisation rules, constitutional identity or other decisions directly affecting the long-term demographic character of the state. This would reduce the scope of exclusion while still protecting the areas most relevant to ancestral continuity. Another possible safeguard would be to hold a referendum among the long-established ancestral population to determine whether they want stricter political membership rules. If a clear majority of those with strong ancestral ties support self-government under stricter boundaries, this would provide a stronger basis for adopting such a system. However, the referendum process itself would need to be carefully designed, because deciding who gets to vote on the boundary is already part of the boundary problem. If stricter political membership is adopted, it should be accompanied by clear rules, appeal rights, evidence standards and protections against arbitrary exclusion. The system should also define whether the threshold applies to all national elections, only certain policy areas, or only eligibility for public office. Without this clarity, the distinction between citizenship and political membership could become unstable and contested. The recommended approach is therefore to consider political membership separately from citizenship. A broad citizenship boundary can help avoid statelessness, while a stricter political membership boundary may better protect ancestral self-determination. The most pragmatic strict threshold would likely be 50% shared ancestry, but this should be balanced with local autonomy, due process and careful limits on how much national power is exercised over citizens who have reduced national political rights. ## Problems with updating ancestral group boundaries Ancestral group boundaries are unlikely to be perfectly fixed forever. Populations change through intermarriage, migration, assimilation, demographic growth and changing evidence. Over time, some external ancestral groups may become deeply rooted in the country or highly assimilated into the national culture. This can create pressure to update the ancestral boundary. However, updating the boundary can create serious problems. If additional ancestral groups are formally included as full national members, the meaning of the nation changes. The state is no longer only protecting the original long-established ancestral population, but a broader population that may have different interests, identities or political preferences. Boundary expansion could weaken the self-determination of the original ancestral group by giving new groups voting power, representation rights and influence over migration, citizenship and constitutional identity. It could also create conflict within the ancestral population, since some people may support inclusion while others may see it as giving up the purpose of ancestral nationalism. Adding groups is also difficult to reverse. Once a group is recognised as part of the nation, later removing it would likely create major conflict and instability. This means that boundary expansion can create a ratchet effect, where membership becomes broader over time but very difficult to narrow again. For this reason, ancestral boundaries should usually be treated as stable and difficult to revise. Corrections may be necessary where the original evidence or reference panel was inaccurate, but this is different from politically expanding the definition of the nation. Administrative correction applies the existing boundary more accurately but boundary expansion would change the boundary itself. A more cautious approach would be to manage demographic and social change through local and regional autonomy, protected communities, federal arrangements, differentiated residency statuses or, in larger cases, new autonomous regions or nation-states. These options can allow different groups to live according to their own preferences without constantly redefining the national ancestral boundary. The main principle is that ancestral boundaries should not be changed casually. Updating them affects national identity, self-determination and political power, so any change would need strong justification and broad consent.
