South-East against North-West Yoruba Descent Divergence

South-East against North-West Yoruba Descent Divergence · Ìpilẹ̀ṣẹ̀

The comparative study of Yorùbá social structures reveals a fundamental cleavage between the North-Western Yorùbá (NWY) polities, historically centered on the Ọ̀yọ́ Empire and the Ẹ̀gbá kingdoms, and the South-Eastern Yorùbá (SEY) polities, encompassing the Òndó, Ìjẹ̀bú, Ọ̀wọ̀, Ìkálẹ̀, and Ìlàjẹ regions . While popular modern discourse frequently treats Yorùbá kinship and civic governance as a uniform matrix, social anthropologists and historians document two sharply contrasting institutional models of descent, land tenure, monarchical authority, and title succession across these zones .

In North-Western Yorùbá societies, kinship is predominantly organized around patrilineal, agnatic descent groups (idílé), where lineage membership, ancestral veneration, land rights, and political titles descend strictly through the male line within large corporate compounds (agbo ilé) . Conversely, South-Eastern Yorùbá communities operate flexible, cognatic (or ambilineal/bilateral) descent systems (ẹbí or umogun), wherein individuals may claim civic identity, inherit land, and compete for titles through either paternal or maternal lines (ọmọ-ìyá and ọmọ-bàbá) based on residency, resource mobilization, and personal achievement . This structural bifurcation is closely mirrored by deep dialectological boundaries established in Yorùbá historical linguistics and by contrasting civic institutions, notably the associative title societies (Oshùgbó, Èghàrègbè) and autonomous female monarchical offices (Lóbùn) characteristic of the southeast .

Conceptual Terminology: Kinship, Morphology, and Etymology

To examine this sociological divergence, one must first analyze the specialized vocabulary of kinship, residential alignment, and corporate belonging in the Yorùbá language.

Idílé (Lineage / Patriline)

Morphology: idí (root, base, bottom) + ilé (house, dwelling).
Tone pattern: Low-High-High (ì-dí-lé).
Sociological gloss: The patrilineal descent group or the unbroken agnatic trunk.
Usage note: In NWY discourse, idílé signifies an exclusive genealogical unit tracing unbroken descent from an eponymous male ancestor. In standard NWY legal and social practice, one cannot belong to more than one idílé simultaneously .

Ẹbí (Kinship Network / Cognatic Family)

Morphology: Derived from the verbal root bí (to give birth, to bear offspring) with the nominalizing nominal prefix ẹ̀-.
Tone pattern: Mid-High (ẹ-bí); in eastern dialects frequently pronounced with low-high or open vocalic shifts.
Sociological gloss: The bilateral or cognatic network of relatives encompassing both maternal and paternal kin.
Usage note: In SEY polities such as Òndó and Ìjẹ̀bú, ẹbí constitutes the primary corporate land-holding and title-claiming descent entity. Unlike the exclusive NWY idílé, an individual in an SEY community actively belongs to multiple ẹbí simultaneously, electing to activate rights within the descent groups of their maternal grandmother, maternal grandfather, paternal grandmother, or paternal grandfather .

Ọmọ-Ìyá versus Ọmọ-Bàbá

Ọmọ-ìyá (Mid-Low-High): Child of the same mother; uterine sibling.
Ọmọ-bàbá (Mid-Low-High): Child of the same father; agnatic sibling.
Morphological gloss: ọmọ (child) + ti (genitive connective, contracted) + ìyá (mother) / bàbá (father).
Sociological operation: In the polygynous households of the northwest, ọmọ-ìyá designates the intimate uterine sub-unit (orí-ororí) that competes against paternal half-siblings (ọmọ-bàbá) for ancestral patrimony . In the southeast, ọmọ-ìyá forms the structural axis along which entire cognatic segments branch out and establish autonomous claims to town titles and agrarian holdings .

Linguistic and Territorial Demarcations

The divergence between North-Western and South-Eastern Yorùbá kinship correlates with the classic linguistic and dialectological maps of Yorubaland established by Abiodun Adetugbo and Femi Akinkugbe .

The NWY Linguistic Complex

North-Western Yorùbá encompasses the Ọ̀yọ́, Ẹ̀gbá, Ìbàdàn, Ọ̀ṣun, and Ìbàràpá dialects . Linguistically, NWY is marked by major historical innovations :

The Proto-Yorùbá voiced velar fricative /ɣ/ and labialized voiced velar /gʷ/ systematically merged into the labio-velar approximant /w/ (e.g., owó for money, ọwọ́ for hand) .
A simplified seven-vowel inventory (/i, e, ẹ, a, ọ, o, u/) resulting from the loss of high non-ATR vowels .
The syntactic development of distinct second-person plural (ẹ) and third-person plural (wọ́n) subject pronouns, alongside the negative marker kò .

This linguistic zone corresponds historically to the savannas and open forest belts where the highly centralized, cavalry-supported state of Old Ọ̀yọ́ established imperial control between the seventeenth and early nineteenth centuries .

The SEY Linguistic Complex

South-Eastern Yorùbá covers the Òndó, Ìjẹ̀bú, Ọ̀wọ̀, Ìkálẹ̀, Ìlàjẹ, Rẹ́mọ, and adjacent southern borderlands stretching toward the Niger Delta creeks . SEY exhibits pronounced phonological conservatism :

It retains the Proto-Yorùbá voiced velar fricative /ɣ/ (orthographically gh) and the labialized velar stop /gʷ/ (orthographically gw), pronouncing ọghọ́ for ọwọ́ (hand) and egho for owó (money) .
It systematically lowered the Proto-Yorùbá high nasal vowels /ĩ/ and /ũ/ to mid vowels /ɛ̃/ (ẹn) and /ɔ̃/ (ọn), rendering irin (iron) as urẹn and ọ̀run (heaven) as ọ̀rọn .
It collapses the second-person plural and third-person plural pronouns into a single indeterminate morpheme (àn án / wẹn), distinguishing person through contextual syntax rather than morphological contrast .

Historically situated in the dense tropical rain forest and coastal waterways, SEY polities maintained long-standing diplomatic, commercial, and artistic relationships with the Kingdom of Benin, developing social structures adapted to localized forest settlements and coastal mercantilism .

Descent Systems: Agnatic Rigidity versus Cognatic Flexibility

The central anthropological debate concerning Yorùbá kinship centers on the distinction between the patrilineal institutions of the northwest and the cognatic institutions of the southeast .

+----------------------------------------------------------------------------------+

The NWY Agnatic Pattern (Ọ̀yọ́ Model)

In the NWY model, thoroughly analyzed by N.A. Fadipe and William Bascom, an individual belongs strictly to the idílé of their biological father .

Compound Cohesion and Patrilocality: Lineage members reside collectively within a large walled residential compound (agbo ilé) governed by the oldest male agnate, the Baálé . A woman leaves her natal home at marriage (patrilocal residence), residing as an ìyàwó (in-marrying wife) in her husband's family compound .
Exclusivity of Rights: Ancestral property, farmland allocated from the lineage estate, residential rooms within the compound, and hereditary ancestral taboos (èèwọ̀) pass strictly through the agnatic chain . While an individual maintains affectionate and ritual connections with their mother's natal compound (ilé ìyá), they cannot claim land, ancestral chieftaincies, or political leadership within that maternal compound under normal customary law .
Lineage-Vested Chieftaincies: Civic offices, such as the noble titles of the Ọ̀yọ́ Mèsì (the supreme kingmaking council of Old Ọ̀yọ́, including the Baṣọ̀run, Agbaakin, and Ṣàmú), belong to specific patrilineages . When a titled chief dies, the vacancy is filled exclusively by an eligible male member selected from that specific agnatic lineage .

The SEY Cognatic Pattern (Òndó and Ìjẹ̀bú Model)

In the SEY model, documented by Peter C. Lloyd, descent is ambilineal and cognatic, creating open, overlapping kindred networks rather than closed patrilineal isolates .

Non-Unilineal Affiliation: An individual traces descent and claims corporate membership through both male and female forebears . An Òndó or Ìjẹ̀bú person belongs simultaneously to the descent groups (ẹbí) of their father's father, father's mother, mother's father, and mother's mother .
Strategic Resource Activation: Because an individual holds latent rights in multiple descent lines, actual operational belonging is optative . A person chooses which ẹbí to actively participate in by attending lineage meetings, contributing to ancestral funeral and installation expenditures, building a residence on the family land, or taking up farming within the family forest tract .
Property and Estate Dispersion: Cocoa farms, timberlands, and urban residential plots are distributed across both paternal and maternal lines . Maternal inheritance is not an anomaly; a person can inherit land from a prosperous maternal aunt or grandfather and establish their primary civic household on that maternal land .
Title Eligibility across Uterine Lines: In sharp contrast to NWY practices, high chieftaincies and hereditary royal rights can be claimed through a maternal link (ọmọ-obìnrin / ọmọ-ìyá) . If a maternal descent group holds eligibility for a town title, a man or woman whose mother was a member of that lineage may actively contest and secure the title, provided they possess the required financial resources, social prestige, and genealogical validation .

The Great Anthropological Debate: Lloyd versus Bender

The nature of Yorùbá descent generated one of the most prominent theoretical disputes in twentieth-century Africanist anthropology, pitting Peter C. Lloyd against Donald R. Bender .

+----------------------------------------------------------------------------------+

Peter C. Lloyd's Model of Regional Duality

Publishing his field findings in Man (1966) and Yoruba Land Law (1962), Peter Lloyd argued that Yorubaland is not socially homogenous . He asserted that :

The Ọ̀yọ́ and northern Yorùbá kingdoms operate strict agnatic segmentary systems comparable to classical unilineal models observed in other West African savanna societies .
The Òndó and Ìjẹ̀bú kingdoms operate genuine cognatic descent systems analogous to Polynesian ambilineal ramages, where descent groups are non-unilineal corporate entities .
This structural difference accounts for the vast variation in customary land tenure, divorce frequency (far higher in cognatic zones where women retain independent lineage property), and political title acquisition across Yorubaland .

Donald R. Bender's Critique and Agnation Thesis

Donald R. Bender contested Lloyd's interpretation in a 1970 study titled Agnatic or Cognatic? A Re-Evaluation of Ondo Descent . Bender argued that :

Lloyd had overstated the structural differences by conflating property inheritance rules with the underlying ideology of descent .
The Òndó and other southern Yorùbá groups remain ideologically patrilineal; patrilateral ties continue to carry superior normative weight, especially in the succession to paramount monarchies .
The apparent "cognatic" practices of the Òndó are secondary adaptations or situational strategies deployed to preserve property within elite families during economic expansions, rather than evidence of a fundamentally different descent architecture .

Post-Structural Reassessments: Eades and Oyěwùmí

Subsequent scholarship challenged the terms of the Lloyd-Bender debate itself .

J.S. Eades (1980) demonstrated that both anthropologists had relied on overly rigid, Western structural-functionalist categories . Eades showed that even in the supposedly strict agnatic northwest, maternal ties (ọmọ-ìyá) play a critical structural role in faction building and resource access, while paternal linkages in the southeast maintain distinct symbolic primacy in specific royal contexts .

Sociologist Oyèrónkẹ́ Oyěwùmí (1997) argued that the debate suffered from an uncritical application of Western patriarchal and biological kinship frameworks . Oyěwùmí maintained that the fundamental organizing principle of Yorùbá society is not biological sex or abstract lineage polarity, but seniority (ọjọ́ orí), defined chronologically within the non-gendered household (ẹbí) . According to Oyěwùmí, colonial and early anthropological accounts distorted Yorùbá social reality by forcing complex, flexible, and non-gendered kin networks into binary European classifications of "patrilineal" versus "matrilineal" descent .

Primary Oral Texts: Proverbs, Oríkì, and Lineage Axioms

The sociological divergence between agnatic exclusivity and cognatic flexibility is documented in traditional oral literature, lineage praise poetry (oríkì), and legal maxims collected across both dialect zones.

Text 1: The Cognatic Principle of Òndó Kinship

This traditional aphorism, recorded among Òndó elders by Jacob Olupona and Peter Lloyd, summarizes the dual-lineage inheritance rights of the South-Eastern Yorùbá .

Original:
Ọmọ obìnrin kì í ṣe àjèjì nínú ẹbí,
Ilé bàbá ni wọ́n ti ń jẹ oyè,
Ilé ìyá ni wọ́n ti ń kọ́lé ọrọ̀.

Literal Gloss:
Ọmọ (child) obìnrin (woman / female) kì í (does not) ṣe (act as / become) àjèjì (stranger) nínú (inside) ẹbí (family/kin-group),
Ilé (house of) bàbá (father) ni (it is where) wọ́n (they) ti (from) ń (continuous) jẹ (eat/inherit) oyè (chieftaincy title),
Ilé (house of) ìyá (mother) ni (it is where) wọ́n (they) ti (from) ń (continuous) kọ́ (build) ilé (house of) ọrọ̀ (wealth/riches).

Idiomatic Translation:
A daughter's child is never a stranger within the family line:
From the father's house they claim the chieftaincy title,
And from the mother's house they build the mansion of wealth.
(Translation: Jacob Olupona [S5]; confirmed by Peter C. Lloyd [S1])

What it means: The proverb asserts that maternal descent is as structurally valid as paternal descent. An individual possesses legitimate lineage rights in both ancestral houses and cannot be disenfranchised on the grounds of uterine connection .
Social function: Used during estate divisions, title competitions, and land disputes in SEY communities to defend the eligibility of individuals claiming land or political office through their mothers or maternal grandmothers .
Concrete scenario: An elite family meeting in Òndó or Ìjẹ̀bú where a rival faction attempts to disqualify a candidate for a family-held chieftaincy because the candidate's link to the ancestor is through a daughter rather than a son. An elder recites this maxim to dismiss the objection and validate the candidate's candidacy .
Linguistic and tonal dynamics: The parallelism between Ilé bàbá (father's house) and Ilé ìyá (mother's house) creates a balanced syntactic structure, emphasizing equilibrium between paternal and maternal inheritance.

Text 2: The Agnatic Invariance of Ọ̀yọ́ Lineage Identity

This classic North-Western Yorùbá saying, recorded by N.A. Fadipe and S.O. Babayemi, reflects the unyielding patrilineal logic of Ọ̀yọ́ kinship .

Original:
Bí a bá ti bíni lẹ́ẹ̀kan, a ti bíni nìyẹn,
A kì í yí orúkọ idílé pa dà sí ti ìyá,
Idílé bàbá ni àkàsọ̀ orí tí a fi ń gun àtẹ́lẹwọ́ oyè.

Literal Gloss:
Bí (if) a (one) bá (should) ti (already) bíni (birth someone) lẹ́ẹ̀kan (once), a (one) ti (already) bíni (birth someone) nìyẹn (that is that),
A (we) kì í (never) yí (twist/change) orúkọ (name of) idílé (patrilineage) pa dà (backwards) sí (toward) ti (that of) ìyá (mother),
Idílé (patrilineage) bàbá (father) ni (is) àkàsọ̀ (ladder) orí (head/destiny) tí (that) a (we) fi (use) ń (continuous) gun (climb) àtẹ́lẹwọ́ (palm of hand / elevated platform) oyè (chieftaincy).

Idiomatic Translation:
Once a person is born, their lineage is fixed forever;
One never switches the ancestral patrilineal name to that of the mother;
It is the father's lineage alone that provides the ladder of destiny by which one ascends to hereditary office.
(Translation: S.O. Babayemi [S13]; comparative gloss by N.A. Fadipe [S6])

What it means: Lineage identity in NWY is singular, immutable, and strictly patrilineal. Maternal ancestry provides affection and refuge, but cannot substitute for the agnatic legal identity required to claim hereditary civic office .
Social function: Serves as a jurisdictional principle in NWY customary courts and kingmaking deliberations, barring individuals from claiming titles or corporate lands outside their father's patrilineal estate .
Concrete scenario: During an interregnum in an Ọ̀yọ́ town, the wealthy son of an imperial princess seeks to claim a hereditary title belonging to the princess's natal patrilineage. The titleholders recite this axiom to confirm his disqualification, advising him to seek titles within his father's lineage .
Dialectal contrast: In NWY, idílé carries absolute corporate exclusivity, whereas in SEY, the flexible term ẹbí supersedes such rigid exclusions .

Sociopolitical and Civic Manifestations

The divergence in descent systems directly generated divergent political architectures, council formats, female authority structures, and associative societies across Yorubaland .

Chieftaincy Systems: Lineage Titles versus Associative Merit

NWY Lineage Representation: In Ọ̀yọ́ and its cultural satellites, the primary governing council is the Ọ̀yọ́ Mèsì, composed of the hereditary heads of the town's most powerful agnatic lineages . Each chief represents his own patrilineal compound and exercises authority delegated through the lineage estate . Military titles (Balógun, Ọ̀tún Balógun, Òsì Balógun) developed as an autonomous hierarchy, distinct from civil administrative titles .
SEY Graded Associative Societies: In Òndó, Ìjẹ̀bú, and Ọ̀wọ̀, political authority is concentrated in graded associative societies and title lodges rather than hereditary lineage seats .
- In Ìjẹ̀bú, the supreme legislative and judicial authority resided in the Oshùgbó (the regional expression of the Ògbóni society), where membership and advancement were achieved through wealth, initiation, and personal merit rather than lineage inheritance .
- In Òndó, governance is managed by the Èghàrègbè (senior civil chiefs), presided over by the Ìwàrẹ̀fà (the six high councilors, led by the Lisa) . Membership in these elite orders is non-hereditary, requiring substantial financial investments, public validation, and title-taking ceremonies open to eligible citizens from any lineage background .

Monarchical Institutions: Sacred Divine Separation versus Executive Balance

The NWY Executive Balance: The Ọ̀yọ́ monarch, the Aláàfin, governed through a delicate institutional balance with the Ọ̀yọ́ Mèsì, led by the Baṣọ̀run . The Ọ̀yọ́ Mèsì retained the constitutional power to reject an autocratic monarch by presenting him with an empty calabash or parrot's eggs, compelling him to commit ritual suicide (ìwàsù) .
The SEY Sacred Divine Monarchy: In SEY polities such as Òndó (Osẹ́mowé), Ìjẹ̀bú (Awùjalẹ̀), and Ọ̀wọ̀ (Ọlọ́wọ̀), the monarch was historically a deeply secluded, sacred sovereign . The king rarely appeared in public except during paramount annual festivals (Ọdún Ọba, Igogo, Agemo) . Day-to-day administrative, legal, and economic governance was conducted entirely by the senior titleholders (Ìwàrẹ̀fà and Oshùgbó), insulating the royal office from immediate political disputes .

Gendered Authority: The Lóbùn of Òndó versus NWY Female Titles

The status of women in political administration reflects the kinship divergence between the zones .

+----------------------------------------------------------------------------------+

The Lóbùn of Òndó: In the SEY kingdom of Òndó, traditions record that the founding sovereign was a woman, Princess Pupupu . While subsequent dynastic succession shifted to male monarchs (Osẹ́mowé), the political constitution preserved a parallel female monarchy headed by the Lóbùn, designated as the Ọba Obìnrin ("Woman King") .
- The Lóbùn occupies an autonomous sacred stool, succeeded strictly by her daughter or a close female relative within her uterine line .
- Without the Lóbùn, no male Osẹ́mowé can be legitimately installed: she alone performs the essential royal coronation rites and invests the monarch with the sacred beaded crown .
- She exercises supreme jurisdiction over all municipal markets and serves as the chief priestess of Ajé (the deity of wealth), possessing independent female chiefs (Òpóòjí) who govern trade and settle female civil disputes .
- Her immense authority is captured in the popular Òndó warning: Wé dẹ́ ṣe Lóbùn i? ("Are you the Lóbùn?"), uttered to caution against overweening pride .
NWY Female Political Roles: In NWY polities such as Ọ̀yọ́ and Ìbàdàn, female power was institutionalized differently . In Ọ̀yọ́, powerful royal women (Ìyá Kékeré, Ìyá Mọsà, Ìyá Láyé) exercised immense influence within the palace interior (ààfin), controlling access to royal shrines and treasury vaults . In civil society, women exercised leadership through the Ìyál'ọ́jà (head of market women) and the Ìyálòde (leader of women's civic affairs) . However, NWY female titleholders did not possess an autonomous hereditary stool capable of crowning the supreme male ruler or exercising separate territorial jurisdiction comparable to the Lóbùn .

Age-Grade Organizations (Ọgbà, Òtú, Ùgbàmà)

SEY Ubiquity: Across the southeast, age-grade sets (Òtú, Ùgbàmà, Ẹlẹ́gbẹ̀) form the foundation of municipal labor, defense, and ritual duties . Young men and women are organized into structured, named cohorts that advance through graded civic ranks every few years, executing road construction, market maintenance, and ancestral masquerade ceremonies .
NWY Atrophy: In NWY polities, age grades atrophied during the imperial era, replaced by centralized military retinues (ẹṣọ́), professional cavalry divisions, and lineage-based compound labor networks .

History and Evolution

The divergence between North-Western and South-Eastern Yorùbá descent and social systems emerged through distinct ecological, economic, and political historical trajectories .

Earliest Formations and Ecological Adaptation (c. 1000-1450 CE)

Archaeological and historical linguistic evidence compiled by Akinwumi Ogundiran and Abiodun Adetugbo suggests that Proto-Yorùbá communities differentiated as populations adapted to distinct ecological biomes . In the northern savannas, nucleated settlements engaged in intensive cereal and yam farming developed corporate patrilineages to maintain indivisible agricultural labor forces and defensive compounds . In the dense southeastern rain forests and coastal river systems, dispersed hamlets relied on mixed tree-cropping, fishing, and regional trade, fostering flexible bilateral kinship networks (ẹbí) and territorial age associations that facilitated cross-settlement mobility .

Imperial Expansion and Regional Specialization (c. 1450-1780 CE)

Between the fifteenth and eighteenth centuries, the political trajectories of the two zones diverged sharply .

Old Ọ̀yọ́ established an extensive savanna empire dependent on cavalry forces, tributary client states, and a centralized royal court governed through hereditary lineage councillors (Ọ̀yọ́ Mèsì) .
The SEY polities, including Òndó, Ìjẹ̀bú, and Ọ̀wọ̀, developed dense urban forest polities situated along crucial trade arteries connecting the Yorùbá hinterland to the coastal lagoons and the Kingdom of Benin . These polities refined associative title societies (Oshùgbó, Èghàrègbè) that integrated diverse migrant lineages into unified civic bodies without requiring uniform agnatic descent .

The Nineteenth-Century Wars (1790-1893 CE)

The collapse of Old Ọ̀yọ́ in the 1830s initiated severe demographic shifts across Yorubaland .

In the northwest and center, millions of refugees established new military polities such as Ìbàdàn and Abẹ́òkúta . While Ìbàdàn introduced military meritocracy, it maintained the agnatic compound structure as the basic unit of civic and military recruitment .
The SEY polities, particularly Ìjẹ̀bú, vigorously defended their territorial sovereignty and trade monopolies . Ìjẹ̀bú closed its roads to interior armies, using the Oshùgbó lodge to formulate unified foreign policy, while Òndó endured internal crises and civil conflicts from 1845 to 1872 before restoring monarchical stability through diplomatic alliances with the British and the Church Missionary Society .

Missionary Contact, Colonial Rule, and Administrative Distortion (1894-1960 CE)

Following the British conquest and the imposition of the Western Nigeria Protectorate, colonial administrators and Christian missionaries generated widespread distortions in Yorùbá legal and kinship institutions .

Colonial officials, influenced by the Rev. Samuel Johnson’s seminal NWY-centric treatise The History of the Yorubas (completed 1897, published 1921), presumed that Ọ̀yọ́ patrilineal customs represented the universal standard for all Yorùbá people .
British Native Courts routinely applied NWY patrilineal inheritance principles (idílé) to SEY jurisdictions in Òndó, Ìjẹ̀bú, and Ọ̀wọ̀, misinterpreting cognatic land claims and uterine title succession as deviations from "customary law" .
Colonial authorities systematically marginalized autonomous female institutions, such as the Lóbùn in Òndó and the Erùwà in Ọ̀wọ̀, refusing to recognize female sovereigns in the official Native Authority councils .

Independence and the Contemporary Era (1960, Present)

In postcolonial Nigeria, the distinction between NWY and SEY descent models remains legally and politically active .

Customary courts in Ondo and Ogun States regularly adjudicate land tenure and chieftaincy disputes according to recognized cognatic principles, upholding the inheritance rights of maternal descendants .
The Oshùgbó society continues to function as an influential arbitral and ritual body across Ìjẹ̀búland, while the Lóbùn institution remains central to the installation and legitimacy of the Osẹ́mowé of Òndó .
In the Yorùbá diaspora across the Atlantic (notably Afro-Cuban Lucumí and Brazilian Candomblé Nagô), elements of both systems merged: the ritual kinship of the initiatory house (ilé) combined the sacred graded lodges of the southeast with the ancestral veneration practices of the northwest .
