Tier 1 Society: This society has no slavery in any form. The society's government armed forces and police services work actively to prosecute any unlawful slavery within the country, and to abolish it beyond its borders where possible. (Signatories of the Amistad Declaration are considered Tier 1 Free Societies by default).
Tier 2 Society: This society has no slavery in any form. The society's government has no interest in actively eliminating slavery beyond its borders, due to a lack of resources or a peace-seeking foreign policy.
Tier 3 Society: Slavery is prohibited in this society, but the government lacks resources to enforce the prohibition fully despite an effort to do so.
Tier 4 Society: Slavery is prohibited in this society, but the government does not attempt to enforce the prohibition, due to geopolitical reasons, or otherwise.
Tier 5 Society: Slavery is prohibited in this society, but social arrangements exist that approximate slave-like conditions – 'voluntary' debt servitude, large-scale prison labor, large-scale civilian labor draft, etc.
Tier 6 Society: Slavery is formally prohibited in this society, but social arrangements exist that are de-facto slave-like conditions – large-scale labor camps and prison labor, either with no proper legal defenses for potential inmates, or where the legal system is clearly drafted to generate a supply of prison labor, large scale civilian labor draft to the benefit of private and semi-private entities, peonage, etc.
Tier 7 Society: Chattel slavery or serfdom is legal in this society, but it is limited either in scope (i.e., enslaved persons slaves constitute a small percentage of the population, and slavery does not play a major role in the country's culture or economy) or in extent (for example, individuals may only be enslaved for a brief period of time, or the society prohibits importation of slaves from beyond its borders).
Tier 8 Society: Slavery constitutes a major element of the society's culture – large amounts of persons are enslaved, and the majority of the country's elite are slavers or derive a large percentage of their profit and social position from the "ownership" of other sapient beings.
Tier 9 Society: The society's culture and politics are thoroughly corrupted by long-term oppression. A large proportion of individuals are held in slavery by other sapients. Torture, forced breeding, mass human sacrifice, or other iniquities of this form are common.
Societies can be also reclassified as Tier 8 if they act to promote slavery abroad or deliberately disrupt abolitionist efforts abroad for ideological efforts, even if they would not otherwise qualify for membership in this tier, including societies pursuing an absolute definition of 'Westphalian' sovereignty.
The Free Kingdom of Allanea is a Tier 1 Society:.
Clarification: It is possible in some cases for several tiers of societies to exist in the borders of one country. For example, the nation's government might be a Tier 3 society, but a terrorist organization controlling a remote area of land within the nation may be a Tier 8 or worse.
