Purpose and description
Enable an agent to identify and interpret activities constituting the Atlantic slave trade, assess the evidence for particular claims, and support responsible historical analysis.
The Atlantic slave trade was the system of commerce that forcibly transported enslaved Africans across the Atlantic, principally to the Americas, from the fifteenth through the nineteenth centuries, involving European and American traders and states alongside African rulers and intermediaries.
It can be Determine whether an episode belongs to the Atlantic slave trade and explain uncertain boundary decisions.; Reconstruct trafficking routes and transfers while preserving gaps and alternative identifications.; Compare counts and mortality estimates only where counting units, coverage, and denominators permit.; Trace documented roles in financing, trafficking, resistance, and suppression.; Evaluate claims about prohibition and cessation against evidence of enforcement and continued trafficking.; Prepare source-qualified historical accounts that preserve enslaved people's identities and agency where evidence permits..
Distinguishing features
An included episode must involve trafficking in enslaved people or a demonstrable enabling, resisting, or suppressing relationship to that trafficking; participation in Atlantic commerce alone is insufficient.
The defining network includes forced Atlantic maritime transportation; an inland transaction belongs only where its connection to that network is established or explicitly qualified.
The model distinguishes the trade in people from the continuing institution of slavery: ending a trading route or prohibiting imports does not establish emancipation.
It records actual itineraries and transfers rather than requiring every episode to follow a triangular route.
It distinguishes people from the transactions and voyage records documenting them, so repeated sale or transportation does not automatically imply additional unique individuals.
Scope
+ Capture, enslavement, and inland transfers where evidence connects them to Atlantic transportation
+ Coastal confinement, embarkation, the Middle Passage, disembarkation, and directly connected resale
+ Trading networks, financing, shipping, markets, and institutions enabling the trade
+ Experiences, mortality, survival, agency, and resistance of enslaved people
+ Regional and chronological variation, prohibition, enforcement, and clandestine continuation
+ Documentary reconstruction, competing interpretations, and uncertainty in identification and estimates
- Slavery as a worldwide institution across all periods
- Indian Ocean, trans-Saharan, and other slave trades except at documented intersections
- Plantation production and everyday slaveholding beyond their direct relationships to trafficking
- Atlantic commerce involving goods or voluntary passengers without a demonstrated connection to slave trading
- Abolition movements in their entirety, beyond actions affecting the trade
- Later racial inequality, collective memory, and reparations policy, except as linked subjects requiring separate models
Characteristics
- Episode and route classification
- capture or inland transfer; coastal confinement; transatlantic passage; connected maritime redistribution; sale; resistance; suppression Locates an episode within the trading system without treating every form of slavery or forced movement as the same phenomenon.
- Historical time coverage
- calendar dates or date intervals, with precision and uncertainty Supports comparison across changing routes, jurisdictions, prohibitions, and archival coverage.
- Geographic connection
- documented or inferred links among inland origins, embarkation places, intermediate stops, landing places, and destinations Separates recorded ports from inferred origins and reveals transfers concealed by a single origin-destination pair.
- People embarked, disembarked, and otherwise accounted for
- persons by episode and counting stage; observed count or estimate with uncertainty Prevents arrivals, departures, transfers, and estimates from being combined as interchangeable totals.
- Mortality during a specified interval
- deaths and percentage of a stated population over a stated interval Makes the denominator and period explicit and prevents unaccounted-for people from automatically being classified as deaths.
- Participant involvement
- person or institution linked to a documented role, action, period, and episode Supports precise attribution of participation and responsibility without assigning uniform roles to whole populations.
- Legal and enforcement position
- authorized, restricted, prohibited, contested, or undetermined under a named jurisdiction and date; enforcement recorded separately Distinguishes historical legal classifications from actual practice and from moral evaluation.
- Evidence status
- directly documented; reconstructed; estimated; disputed; unknown Allows an agent to decide whether a claim can be reported, needs qualification, or requires further research.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 19 findings · 33 questions.
Trade boundaries and routes Identifies which movements and connected activities constitute the Atlantic slave trade.
The trade cannot be recognized reliably through an ocean crossing, a port name, or a generic reference to slavery alone.
Connected trafficking episodes
Tests the connection between a particular episode and forced Atlantic transportation.
Episode membership
Record the grounds for including capture, confinement, transportation, or sale within this trading system.
- What evidence connects this episode to the transportation of enslaved African people through Atlantic trading networks? boundary
- Does the episode describe trafficking, an enabling activity, or slaveholding that belongs primarily to a neighbouring model? definition
Itineraries and periods
Represents actual routes, transfers, and temporal coverage without assuming a fixed circuit.
Route reconstruction
Distinguish intended destinations, observed movements, connected transfers, and uncertain geographic identifications.
- Which embarkation places, stops, landing places, and subsequent transfers are documented, and which are inferred? provenance
- What dates and geographic limits define this route or regional phase, and what evidence supports those limits? boundary
Coercion, experience, and resistance Examines how people were enslaved, confined, transported, and able to act under coercion.
Commercial records alone can obscure violence, lived experience, and the agency of the people trafficked.
Enslavement and confinement
Tracks the evidenced mechanisms connecting loss of freedom to inland and coastal custody.
Pathways into trafficking
Record how people entered the trafficking system without treating traders' justifications as established accounts.
- What is known about how these people were enslaved and transferred, and whose account supports that reconstruction? provenance
- Which claims about capture, purchase, legal status, or consent originate with participants seeking to justify the transaction? provenance
Passage, survival, and agency
Addresses conditions aboard ships, human losses, resistance, and outcomes for survivors.
Conditions and responses
Record confinement, provisioning, illness, violence, mutual support, escape, and revolt where supported by evidence.
- What evidence describes conditions and violence during this passage, and how does its authorship limit what can be concluded? provenance
- What actions by enslaved people are documented, and how should interpretations of their intentions be qualified? action
- What happened to identified survivors after landing, escape, revolt, or interception, and where does the record end? provenance
Commercial and institutional organization Connects trafficking episodes to their participants, financial arrangements, shipping capacity, and markets.
The model must explain how the trade operated while distinguishing documented roles from broad collective attribution.
Participants and authority
Identifies the actions and powers of merchants, intermediaries, ship operators, purchasers, and governing institutions.
Documented participation
Attribute specific involvement to identifiable actors within a stated time and place.
- Which actors organized, financed, supplied, authorized, transported, sold, or purchased people in this episode? provenance
- What evidence distinguishes direct action, delegated authority, financial benefit, and an association that does not establish participation? boundary
Finance, shipping, and markets
Examines the resources and transactions sustaining particular voyages and trading networks.
Transaction and resource chain
Connect documented credit, insurance, goods, vessels, payments, and sales without presuming a universal business pattern.
- Which contracts, accounts, or other records establish how this voyage or trading operation was resourced and paid for? provenance
- When comparing prices, revenues, or returns, what currencies, dates, costs, and missing transactions must be accounted for? measurement
Prohibition, suppression, and continuation Distinguishes changes in law from enforcement, evasion, and the outcomes of intervention.
A prohibition date cannot stand for the end of trafficking or the emancipation of the people affected.
Jurisdiction and legal change
Identifies what a legal measure covered and when and where it applied.
Legal reach
Record the acts, actors, territories, and vessels covered by authorizations, restrictions, or prohibitions.
- Which legal instrument applied to this activity, in which jurisdiction, and from what effective date? provenance
- Did the measure address trading, transportation, importation, ownership, or emancipation, and what remained outside its reach? boundary
Enforcement, evasion, and outcomes
Examines interceptions, adjudication, clandestine practices, and the subsequent treatment of people removed from ships.
Suppression in practice
Assess interventions through observed outcomes rather than legal declarations or official labels alone.
- What evidence establishes enforcement, evasion, or continued trafficking after prohibition? provenance
- What became of the people removed from intercepted vessels, including any subsequent compulsory labour or renewed enslavement? provenance
- What evidence would justify describing trafficking as ended within this geographic and temporal scope? boundary
Historical evidence and reconstruction Controls how archival traces become claims about people, voyages, scale, and historical meaning.
Surviving records are uneven, often produced by perpetrators or administrators, and do not directly supply a complete count or account.
Source perspective and identification
Evaluates authorship, terminology, record linkage, and the recovery of personal identities.
Traceable historical claims
Preserve source wording and context while distinguishing historical classifications from the model's descriptions.
- Who created each source, for what purpose, and what experiences or transactions was it unlikely to record? provenance
- What supports linking names, ships, or episodes across records, and which alternative identifications remain plausible? provenance
- How should an agent quote dehumanizing archival terms while clearly attributing them and preserving the personhood of those described? action
Counts, estimates, and comparison
Separates recorded observations from reconstructions and establishes valid units of comparison.
Population and voyage estimates
Specify counting stages, duplicate handling, missing records, and assumptions behind numerical claims.
- Does this number count unique people, embarkations, disembarkations, transactions, or voyages, and how are repeated transfers handled? measurement
- How were missing voyages or population counts estimated, and what uncertainty or revision history accompanies the result? measurement
- Are regional or chronological comparisons valid given differences in record survival, coverage, and reconstruction methods? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

- Triangular trade - Triangular trade describes a three-region commercial circuit; Atlantic slave trading also operated through routes that were not triangular.
- Intra-American slave trade - This involved trafficking between locations in the Americas rather than transportation from Africa across the Atlantic.
- Trans-Saharan slave trade - This used routes across the Sahara rather than Atlantic shipping routes.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of Atlantic slave trade this model covers, and on what evidence? provenance
What the second pass must settle
- Which chronological endpoints best fit the registry's intended scope, and should regional endpoints be recorded instead of one universal start and end?
- How should intra-American redistribution and non-American Atlantic destinations be bounded within this entry while preserving their connections to the wider trafficking system?
- Which sources and reconstruction methods provide defensible estimates of scale and mortality for each region and period, especially where records are sparse?
- Where can African origins, personal identities, and survivor experiences be recovered without treating embarkation ports or traders' classifications as reliable substitutes?
- Which scholarly disagreements over participation, profitability, and causal explanations should be represented as competing interpretations rather than settled findings?
