Yorùbá arms and fortification from iron-age edged weapons and Ọ̀yọ́'s cavalry economy through the nineteenth-century transition to imported firearms, and the archaeological evidence for defensive earthworks going back centuries before European contact.
The Yorùbá wey dem quote, the proverbs, oríkì, ẹsẹ Ifá, word list headwords, Odù names and citations dey exactly as the corpus record dem, for every language.
Yorùbá military technology pass through two different systems before colonial period. For di open savanna wey dey north of di forest, Old Ọ̀yọ́ build empire on top cavalry wey dem import, trade wey depend on horses wey no fit reproduce for di south wey tsetse fly full. For di nineteenth century, after Ọ̀yọ́'s collapse, war come shift enter di forest area and enter infantry armies wey dey use firearms wey dem import, and e reach climax with breech-loading rifles for Kiriji war. Underneath di two systems, long tradition of big earthwork fortification dey ground, wey archaeology don show say e start centuries before cavalry or firearms even matter. Dis file cover weapons, cavalry logistics, how dem take adopt firearms, fortification engineering and di archaeological evidence. Di tori of which war use which technology and di time wey dem use am dey inside [[history-nineteenth-century-wars]] and we no repeat am here; organizational structure and command dey inside [[the-yoruba-military-system]].
Before firearms enter, Yorùbá armies dey fight with iron weapons wey local blacksmiths forge, and with wooden shock and missile weapons. Di way war take depend on iron work connect directly with di worship of Ògún, di òrìṣà of iron and combat; dat ritual side dey well covered for anoda place for dis section.
Missile warfare depend on self-bow (ọfà) pass crossbow, wey only appear for few documented instances across di wider Guinea forest region. Dem dey put small barbed iron point for arrow head, and for hunting and war alike, dem dey often rub botanical poison for body; di light draw weight of regional bows make poison di main tin wey dey kill instead of kinetic force, so dat even small wound fit incapacitate person.
For close combat, Yorùbá fighters dey carry spears (ọ̀kọ̀) wey get heavy type for thrusting and lighter type for throwing, plus two different types of sword: di idà, long straight double-edged blade wey dem dey associate with officers, cavalry and noble people, and heavier single-edged cutting blades wey come from farm cutlasses and billhooks, wey serve as standard slashing weapon for infantry. Clubs and short stabbing daggers complete di personal arsenal.
Di way Ọ̀yọ́'s take dominate from around 1600 reach 1836 depend on cavalry, and cavalry for West Africa na trade good problem before e be tactical problem. Horses no fit sustain breeding population for tsetse fly area, because di fly dey carry trypanosomiasis, sickness wey dey kill horse; and di tsetse belt cover most of di forest zone south of di savanna margin. Ọ̀yọ́ dey open woodland and savanna north of dat belt, so dem fit use cavalry, but dem no fit breed enough new horses by demselves and dem depend on continuous import of horses from Borgu, Nupe and Hausa traders across and beyond di Niger.
Dis dependency shape di whole political economy of Ọ̀yọ́'s. To maintain di horse trade require tribute networks, slave-raiding to get wealth to pay for imports, and long-distance trade routes wey link Sahel to Atlantic coast, structure wey Robin Law study of di Ọ̀yọ́ cavalry state describe as di main strategic constraint of di empire. Dem dey do most of dia war campaigns for dry season, when hard ground favor horse movement and tsetse activity reduce, and Ọ̀yọ́'s cavalry give dem decisive superiority pass dia forest neighbours wey no fit field any horse army, including early campaigns against Dahomey.
Dat advantage disappear as Ọ̀yọ́ self collapse. Di nineteenth-century wars, wey dem fight mostly inside di forest belt after di empire fall, na on foot dem fight am; cavalry play very small role for di wars between di successor states because Ìbàdàn, Ìjàyè and di eastern kingdoms all dey operate inside or near tsetse area.
Firearms reach di Yorùbá coast in small numbers during di eighteenth century, but powers for interior no adopt dem in large scale until di wars of di 1820s, wey happen around di same time as di Ọ̀wu war and di fall of Old Ọ̀yọ́. Di first generation of weapons wey dey widely used na long-barrel flintlock muzzle-loaders, wey people generally dey call Dane guns (ìbọn) across West Africa. Dem slow to reload, usually several minutes per shot, and dem no dey accurate from far distance, and dis shape nineteenth-century Yorùbá infantry tactics around massed volley fire wey close-range cutlass fight dey follow immediately, and around rotating firing ranks so dat continuous fire fit dey maintained while soldiers dey reload individual muskets.
Local blacksmiths quickly adapt to di new technology instead of to depend completely on imports. When manufactured shot no dey, smiths dey cast lead pellets or cut iron rods into improvised slugs, repair damaged locks, put new wooden stocks for broken barrels, and for some cases dem produce coarse local gunpowder from saltpetre, sulphur and charcoal, even though imported powder still remain wetin dem prefer because e dey catch fire better.
Di main technological shift happen during di Sixteen Years War (Kiriji war, 1877 go reach 1893), wey dem narrate full for [[history-nineteenth-century-wars]]. Di Ẹ̀kìtìparapọ̀ coalition, wey get supply through diaspora network for Lagos wey Ìjẹ̀ṣà and Èkìtì returnees form, import modern breech-loading rifles, including Snider-Enfield and Martini-Henry weapons, join with metallic cartridges. Dis weapons get far range, dem dey shoot accurately, and dem dey fire fast pass Ìbàdàn Dane guns, and Ìbàdàn no fit get dat kind weapons even though dem beg Lagos suppliers many times. Dis difference for firepower na di direct technological reason why static, entrenched warfare happen for Kiriji and Ìmẹ̀sí-Ilé camps: none of di sides fit pursue di other side comot with open attack once di eastern confederacy get rifles wey fit scatter mass advance from far distance, and di two armies come stay face each other from fortified positions for many years, arrangement wey close to trench warfare pass di open campaigns of earlier decades.
Yorùbá towns for savanna and forest areas use earthwork fortifications defend deir territory: dem dig outer ditch, pack di sand go inside to build high wall (rampart), reinforce am with laterite or clay layers for drier areas, and cut straight embankments enter laterite ground for wetter forest areas of Ìjẹ̀bú and Èkìtì, and sometimes dem channel groundwater enter am to form wet moat. Bigger capitals get more than one circle of walls, with di outer wall enclosing farmland so dat people wey dem surround fit sustain deirself during long siege. Fortified gates wey soldiers dey guard well-well dey control entry, and plenty times dem dey serve as toll points.
Two siege methods dominate di documented record: direct attack on top gates and weak areas using ladders and fire, and di slower method of encirclement and blockade, where di attacking army cut off di town water and farm with deir own counter-earthworks until di defenders surrender. Di Ìjàyè war of 1860 go reach 1862 na di best documented example of dis blockade method; di command decisions for dat campaign belong to [[people-ibadan-and-its-war-chiefs]], no be inside dis file.
Archaeology confirm say big-scale defensive earthwork construction for dis region happen centuries before transatlantic firearms trade start, and for some cases, centuries before Islam reach di interior.
Di biggest individual site na Sungbo's Ẹrẹdò, one massive ditch-and-bank system wey surround di historic center of Ìjẹ̀bú kingdom, wey long pass one hundred kilometers round, with ditch depths wey reach several meters below di earthen bank for some places. Di exact time wey dem build am na matter of real debate, no be settled matter. Patrick Darling original radiocarbon work, based on samples wey im take during im 1990s survey, bring dates wey cluster around tenth and eleventh centuries CE (with some individual determinations as early as ninth century). More recent excavation and dating work don produce later range, wey cluster around late fourteenth and early fifteenth centuries. Di two positions rest on real radiocarbon evidence from different excavation campaigns, and dis file no dey judge between dem; reader suppose treat any confident date for Ẹrẹdò's origin as just one position inside open scholarly disagreement, no be settled fact.
For Ọ̀yọ́-Ilé, di former imperial capital, archaeological mapping wey start with Robert Soper fieldwork for 1970s and continue with later interdisciplinary surveys don document multiple concentric wall circuits wey surround di city center, with di main archaeological site covering area wey close to three thousand hectares; bigger numbers wey people sometimes quote for di site outer boundaries during im eighteenth-century peak no get strong support for di sources wey dem consult for dis file, and dem no repeat am here. Di site preserve substantial evidence of di city material culture beyond im fortifications, including carved wooden posts wey Soper recover and document.
Di record wey dem consult for dis file no see reliable archaeological documentation of specific equestrian artefacts, bridle fittings or stirrups, wey dem recover from excavation for Old Bara or similar Ọ̀yọ́-region burial sites; where dem discuss such items for broader literature on Ọ̀yọ́'s cavalry, dem generally treat dem as historically and ethnographically documented imports, no be as excavated archaeological finds, and dis file no claim otherwise.

How Yorùbá armies were organised and commanded, from the mounted nobility of Old Ọ̀yọ́ to the achieved war-chief ladders of the nineteenth-century successor states, and how campaigns were recruited, supplied and fought.
How nineteenth-century Yoruba warfare remade society, through refugee city-founding, the economics of captive and pawn labour, the Ajele resident-administrator system, and new patterns of stratification and gender.
Why the nineteenth-century Yoruba wars read differently depending on whether the source is oral tradition, academic history, or a colonial missionary account, illustrated with the Battle of Òsogbo's tactics and the record's treatment of Òwú's origins.
How Yorùbá warfare was bound up with the worship of Ògún, pre-campaign Ifá divination, herbal and spiritual war medicine, and iron oaths sealing military alliances, and how tradition, academic history and colonial missionary sources read that ritual dimension three different ways.
