Oyo Empire
The Oyo Empire (c. 1400 - 1835) was a West African empire of what is today western Nigeria. The empire was established by the Yoruba in the 15th century and grew to become one of the largest West African states encountered by colonial explorers. It rose to preeminence through wealth gained from trade and its possession of a powerful cavalry. The Oyo Empire was the most politically important state in the region from the mid-17th to the late 18th century, holding sway not only over other Yoruba states, but also over the Fon kingdom of Dahomey (located in the state now known as the Republic of Benin).
Origins
Due to the prevalence of oral history in Old Oyo, the factual origins of the state are nebulous at best. The literal truth to either story is irrelevant in comparison to the notion of ethnic identity and cultural unity they instill and lend to the foundations of the empire.[1] Modern historians do agree that Oyo was founded by Yoruba immigrants from Ife in the late 14th century. By the end of the 15th century, metropolitan Oyo was established.[2]
A Conquest Deferred
The founding of Oyo is related via Yoruba and Edo traditional accounts as a sort of military mishap. According to these accounts, the second prince of Ife, Oranyan (also Oranmiyan), made an agreement with his brother to launch a punitive raid on their northern neighbors for insulting Oduduwa. On the way to the battle, the brothers quarreled and the army split up.[1] Oranyan's force wasn't large enough to make a successful attack, so he wandered the southern shore until reaching Bussa. It was there that the local chief entertained him and provided a large snake with a magic charm attached to its throat. The chief instructed Oranyan to follow the snake until it stopped somewhere for seven days and disappeared into the ground. Oranyan followed the advice and founded Oyo where the serpent stopped. The site is remembered as as Ajaka. Oranyan made Oyo his new kingdom, leaving all his treasures in Ife and allowing another king named Adimu to rule there.[3]
Early Period
Oranyan, first Alaafin (king) of Oyo, was succeeded by Ajaka. This Alaafin was deposed, because he lacked Yoruba military virtue and allowed his sub-chiefs too much independence. Leadership was then conferred upon Ajaka's brother, Sango, who was later deified as the god of thunder and war. Ajaka was restored after Sango's suicide; the latter being a hated tyrant. Ajaka returned to the throne thoroughly more warlike and oppressive. His successor, Kori, managed to conquer the rest of what later historians would refer to as metropolitan Oyo.[3]
Oyo-Ile
The heart of metropolitan Oyo was its capital at Oyo-Ile, (also known as Katunga or Old Oyo or Oyo-oro).[4] The two most important structures in Oyo-Ile were the alaafin's palace and his market. The palace was at the center of the city close to the king's market called Oja-oba. Around the capital was a tall earthen wall for defense with 17 gates. The importance of the two large structures (the palace and the Oja Oba) signified the importance of the king in Oyo.
Nupe Occupation
Oyo had grown into a formidable inland power by the end of the 14th century. For over a century, the Yoruba state had expanded at the expense of its neighbors. Then, during the reign of Onigbogi, Oyo suffered military defeats at the hands of the Nupe led by Tsoede.[2] Sometime around 1535, the Nupe occupied Oyo and forced its ruling dynasty to take refuge in the kingdom of Borgu.[5] The Nupe went on to sack the capital, destroying Oyo as a regional power until the early 17th century.[6]
Imperial Period
Oyo went through an interrugnum of 80 years as an exiled dynasty after its defeat by the Nupe. Oyo then reemerged, more centralized and expansive than ever. It would not be satisfied with simply retaking Oyo but with the establishment of its power over a vast empire.[5] During the 17th century Oyo began a long stretch of growth, becoming a major empire.[6] Oyo never encompassed all Yoruba-speaking people but it was by far the most populous kingdom in Yoruba history.[7]
Reconquest and Expansion
The key to Yoruba reconquest of Oyo would be a stronger military and a more centralized government. Taking a cue from their Nupe enemies, the Yoruba rearmed not only with armor but cavalry.[5] Alaafin Ofinran succeeded in regaining Oyo's original territory from the Nupe.[2] A new capital, Oyo-Igboho, was constructed, and the original became known as Old Oyo.[2] The next Alaafin, Egonoju, conquered nearly all of Yorubaland.[2] After this, Alaafin Orompoto led attacks to obliterate the Nupe to ensure Oyo was never threatened by them again.[2] During the reign of Alaafin Ajiboyede was the first Bere festival, an event that would retain much significance among the Yoruba long after the fall of Oyo.[2] And it was under his successor, Abipa, that the Yoruba were finally compelled to repopulate Oyo-Ile and rebuild the original capital.[2] Despite a failed attempt to conquer the Benin Empire sometime between 1578 and 1608,[2] Oyo continued to expand. The Yoruba allowed autonomy to the southeast of metropolitan Oyo where the non-Yoruba areas could act as a buffer between Oyo and Imperial Benin.[8] By the end of the 16th century, the Ewe and Aja states of modern Benin were paying tribute to Oyo.[9]
The Dahomey Wars
The reinvigorated Oyo Empire began raiding southward at least as early as 1682.[10] By the end of its military expansion, Oyo's borders would reach to the coast some 200 miles southwest of its capital.[11] It met very little serious opposition after its failure against Benin until the early 18th century. In 1728, the Oyo Empire invaded the Kingdom of Dahomey in a major and bitter campaign.[10] The force that invaded Dahomey was entirely composed of cavalry.[12] Dahomey, on the other hand, possessed no cavalry but many firearms. These firearms proved effective in scaring the horses of Oyo's cavalry and preventing them charging.[13] Dahomey's army also built fortifications such as trenches, which forced the Oyo army to fight as infantry.[14] The battle lasted four days, but the Yoruba were eventually victorious after their reinforcements arrived.[14] Dahomey was forced to pay tribute to Oyo after the latter's hard-fought victory. This would not end the fighting, however, and the Yoruba would invade Dahomey a total of seven times before the little kingdom was fully subjugated in 1748.[15]
Later Conquest
Oyo's cavalry enabled them to launch campaigns of conquest and suppression over great distances. The Oyo army also proved capable of surmounting fortifications but had to withdraw when supplies ran out to feed the army.[16] It is also notable that Oyo didn't use guns in its major conquest. Furthermore, guns were little use against Oyo's army, which is possibly why they waited until the 19th century to adopt them.[16] In 1764, a joint Oyo-Dahomey force crushed an Asante army.[10] The Oyo victory would define borders between the two states.[10] Oyo led a successful campaign into Mahi territory north of Dahomey in the late 1700s.[10] The Yoruba also used the forces of their tributaries. A striking example of this is the 1784 naval blockade by an Oyo-Dahomey-Lagos force of Badagri.[17]
Organization
The original incarnation of Oyo consisted of metropolitan Oyo and little more. But with the advent of its imperial expansion, Oyo was reorganized to better manage its vast holdings within and outside of Yorubaland. It was divided into four layers defined by relation to the core of the empire.[18] These layers were Metropolitan Oyo, southern Yorubaland, the Egbado Corridor and Ajaland.
Metropolitan Oyo
Metropolitan Oyo corresponded, more or less, to the Oyo state prior to the Nupe invasion.[18] This was the hub of the empire where the Yoruba spoke the Oyo dialect.[8] Metropolitan Oyo was divided into six provinces with three on the west side of the Ogun River and three to the river's east.[8] Each province was supervised by a governor appointed directly by the alaafin.[19]
Yorubaland
The second layer of the empire was composed of the towns closest to Oyo-Ile, whom were recognized as brothers.[18] This area was south of metropolitan Oyo, and its Yoruba inhabitants spoke different dialects from that of Oyo.[8] These tributary states were led by their own rulers titled Obas.[19] These vassal courts were headed by their native leaders (according to local custom) but had to be confirmed by the Alaafin of Oyo.[19]
Egbado Corridor
The empire's third layer was the Egbado Corridor southwest of Yorubaland. This area was inhabited by the Egba and Egbado and was very valuable in respect to Oyo's trade with the coast. The Egba and Egbado tributaries were allowed, like their Yoruba counterparts, to rule themselves. They were, however, supervised by Ajele.[18] These were agents appointed by the Alaafin to oversee his interest and monitor commerce. The lead representative of Oyo in the corridor was the Olu, ruler of the town of Ilaro.[11]
Ajaland
Ajaland was the last layer added to the empire and also the most restive since tribute could only be exacted by threat of far-flung expeditions.[18] This territory extended from the non-Yoruba areas west of the Egbado Corridor far into Ewe controlled territory in modern Togo.[8] This area, like all tributary states, was allowed a fair degree of autonomy as along as taxes were paid, the orders from Oyo were strictly followed and access to local markets was made available to Oyo merchants.[9] Tribute was often taken in slaves, and if that meant the tributary had to make war on someone to get them (as with Dahomey), so be it.[20] To disobey commands sent from Oyo meant wholesale slaughter of the community, as occurred in Allada in 1698.[9]
Political Structure
The Oyo Empire developed a highly sophisticated political structure to govern its territorial domains. It is unknown precisely how much of this structure existed prior to the Nupe invasion. Some of Oyo's institutions are clearly derivative of early accomplishments in Ife. After reemerging from exile in the early 17th century, Oyo took on a noticeably more militant character. The influence of an aggressive Yoruba culture is exemplified in the standards placed on the Alaafin and the roles of his council.
The Alaafin
The Alaafin was the head of the empire and supreme overlord of the people.[21] He was responsible for keeping tributaries safe from attack, settling internal quarrels between sub-rulers, and mediating between those sub-rulers and their people.[21] The Alaafin was also expected to lavish his subordinates with honors and gifts.[21] In return, all sub-rulers had to pay homage to the Alaafin and renew their allegiance at annual ceremonies.[19] The most important of these was the Bere festival marking the acclimation of successful rule by the Alaffin.[19] After the bere festival there was supposed to be peace in Yorubaland for three years.[19]
Selection of the Alaafin
The Oyo Empire was not a hereditary monarchy, nor an absolute one.[21] The Alaafin was carefully selected by the Oyo Mesi and was not always directly related to his predecessor, though he did have to be descended from Oranyan and to hail from the Ona Isokun ward (which is one of the three royal wards).[21] At the beginning of the Oyo empire it was usually the Alaafin's oldest son that succeeded his father to the throne. However, this sometimes led to the oldest son, the Aremo, hastening the death of his father. In order to prevent this (and in order to strengthen the power of the Oyo Mesi over the Alaafin), in later times the practice was instituted whereby the Aremo had to commit suicide when his father died. Independently of the possible succession to his father, the Aremo was quite powerful in his own right. For instance, by custom the Alaafin could not leave the palace, except during the important festivals, which curtailed his power in practice. By contrast, the Aremo was allowed to leave the palace. This led noted historian Johnson to observe: "The father is the king of the palace, and the son the King for the general public".[22] The two councils which checked the Alaafin had a tendency to select a weak Alaafin after the reign of a strong one to keep the office from becoming too powerful.[23]
The Ilari
Certain religious and government officials, usually eunuchs, were appointed by the Alaafin.[24] These officials were known as the ilari or half-heads because of the custom of shaving half of their heads and applying what was believed to be a magical substance into it.[25] There were hundreds of Ilari divided evenly among the sexes.[25] Junior members of the Ilari did menial tasks while seniors acted as guards or sometimes messengers to the other world via sacrifice.[25] They had titles referencing the king such as oba l'olu ("the king is supreme") or madarikan ("do not oppose him").[25] They also carried fans of green or red as credentials.[25]
All sub-courts of Oyo had Ilari who acted as both spies and taxmen[19] Oyo appointed these to visit and sometimes reside in Dahomey and the Egbado Corridor to collect taxes and spy on Dahomey's military successes so that the Alaafin could get his cut.[26] Similar, though far older, officials existed in Ife as attested by terracotta art depicting them.[26]
The Councils
While the Alaafin was supreme overlord of the people, he was not without checks on his power. The Oyo Mesi and the Yoruba Earth cult known as Ogboni kept his power in check.[24] The Oyo Mesi spoke for the politicians while the The Ogboni spoke for the people backed by the power of religion.[23] The power of the Alaafin in relation to the Oyo Mesi and Ogboni depended on his personal character and political shrewdness.
The Oyo Mesi
The Oyo Mesi was the council that selected the Alaafin.[21] Their political power was tied to their control of the military.[27] They had seven members, the heads of the seven non-royal wards of Oyo, who consulted the Ifa oracle for approval from the gods; thus, new Alaafins were seen as appointed by the gods.[21] They were then regarded as Ekeji Orisa meaning "companion of the gods" upon ascension to the throne.[21]
The bashorun was head of the Oyo Mesi and a sort of prime minister.[24] Every year he held a religious divination to determine if the gods still held favor with the alaafin and during the later years of the Oyo empire he had the de facto power to dethrone an alaafin.[24]
The Ogboni
The Ogboni was a very powerful secret society composed of freemen noted for their age, wisdom and importance in religious and political affairs.[24] Its members enjoyed immense power over the common people due to their religious station. A testament to how widespread the institution was is the fact that there were Ogboni councils at nearly all sub-courts within Yorubaland.[24] Aside from their duties in respect to the worship of the earth, they were responsible for judging any case dealing with the spilling of blood.[24] The leader of the Ogboni had the unqualified right of direct access to the Alaafin on any matter.[24]
Removing an Alaafin
Alaafins could not legally be deposed, but in later periods could be compelled to commit suicide if the Oyo Mesi (and maybe also the Ogboni) disapproved of their actions.[24] The Alaafin could also be removed if the people suffered serious reverses.[24] In either instance, the Bashorun would be commissioned to present the Alaafin with an empty calabash or a dish of parrot's eggs.[24] The Bashorun would then proclaim "the gods reject you, the people reject you, the earth rejects you".[24]
Military
There was a heigh degree of professionalism in the army of the Oyo Empire.[28] Its military success was due in large part to its cavalry as well as the leadership and courage of Oyo officers and warriors.[28] Because its main geographic focus was north of the forest, Oyo enjoyed easier farming and thus a steady growth in population.[28] This contributed to Oyo's ability to consistently field a large force. There was also an entrenched military culture in Oyo where victory was obligatory and defeat carried the duty of committing suicide.[23] This do-or-die policy no doubt contributed to the military aggressiveness of Oyo's generals.[23]
Cavalry
The Oyo Empire was the only Yoruba state to adopt cavalry; it did so because most of its territory was in the northern savannah.[12] The origin of the cavalry is disputed; however, the Nupe, Borgu and Hausa in neighboring territories also used cavalry and may have had the same historical source.[29] Oyo was able to purchase horses from the north and maintain them in metropolitan Oyo because of partial freedom from the tsetse fly.[30] Cavalry was the long arm of the Oyo Empire. Late 16th and 17th century expeditions were composed entirely of cavalry.[12] There were drawbacks to this. Oyo could not maintain its cavalry army in the south but could raid at will.[10]
Cavalry in highly developed societies such as Oyo was divided into light and heavy.[12] Heavy cavalry on larger imported horses was armed with heavy thrusting lances or spears and also with swords.[12] Light cavalry on smaller indigenous ponies was armed with throwing spears or bows.[31] Oyo's cavalry forces included not only nobles, the norm in West African warfare, but foreign slaves from the Hausa, Nupe and Bornu states.[32]
Infantry
Infantry in the region around the Oyo Empire was uniform in both armor and armament. All infantry in the region carried shields, swords and lances of one type or another.[10] Shields were four feet tall and two feet wide and made of elephant or oxide.[33] A three foot long heavy sword was the main armament for close combat.[33] The Yoruba and their neighbors used triple barbed javelins which could be thrown accurately from about 30 paces.[10]
Structure
The Oyo Empire, like many empires before it, used both local and tributary forces to expand its domains. The structure of the Oyo military prior to its imperial period was simple and closer aligned to the central government in metropolitan Oyo. This may have been fine in the 15th century when Oyo controlled only its heartland. But to make and maintain farther conquest, the structure underwent several changes.
The Eso
Oyo maintained a semi-standing army of specialist cavalry soldiers called the Eso or Esho.[34] These were 70 junior war chiefs who were nominated by the Oyo Mesi and confirmed by the Alaafin.[34] The Eso were appointed for their military skill without regard to heritage and were led by the Are-Ona-Kakanfo.[23]
The post of Are-Ona-Kakanfo was established after Oyo's return from exile as the supreme military commander.[35] He was required to live in a frontier province of great importance to keep an eye on the enemy and to keep him from usurping the government.[23] During Oyo's imperial period, the Are-Ona-Kakanfo personally commanded the army in the field on all campaigns.[23]
The Metropolitan Army
Since the Are-Ona-Kakanfo could not reside near the capital, arrangements had to be made for the latter's protection in case of emergency. Forces inside metropolitan Oyo were commanded by the Bashorun, leading member of the Oyo Mesi.[35] As stated earlier, Metropolitan Oyo was divided into six provinces divided evenly by a river. Provincial forces were thus grouped into two armies, under the Onikoyi and the Okere for the east and west side of the river respectively.[35] Lesser war chiefs were known as Balogun, a title carried on by the soldiers of Oyo's successor state, Ibadan.[36]
The Tributary Army
Tributary leaders and provincial governors were responsible for collecting tribute and contributing troops under local generalship to the imperial army in times of emergency.[8] Occasionally, tributary leaders would be ordered to attack neighbors even without the backing of the main imperial army.[8] These forces were often utilized in Oyo's more distant campaigns on the coast or against western states like Asanteman or the Mahi.
Commerce
Oyo became the southern emporium of the Trans-Saharan trade. Exchanges were made in salt, leather, horses, kola nuts, ivory, cloth and slaves.[30] The Yoruba of metropolitan Oyo were also highly skilled in craft making and iron work.[30] Aside from taxes on trade products coming in and out of the empire, Oyo also became wealthy off the taxes imposed on its tributaries. Taxes on the kingdom of Dahomey alone brought in an amount estimated at 638 thousand dollars a year.[28]
Slave Trade
Oyo's imperial success made Yoruba a lingua franca almost to the shores of the Volta.[30] Toward the end of the 18th century, the Oyo army was neglected as there was less need to conquer.[18] Instead, Oyo directed more effort towards trading and acted as middlemen for both the Trans-Saharan and Trans-Atlantic slave trade.[18] Europeans bringing salt arrived in Oyo during the reign of King Obalokun.[2] Thanks to its domination of the coast, Oyo merchants were able to trade with Europeans at Porto Novo and Whydah.[9] Here the Oyo Empire's captives and criminals were sold to Dutch and Portuguese buyers.[37]
Zenith
By 1680, the Oyo Empire spanned over 150,000 square kilometers.[38] It reached its height of its power in the 18th century.[9] And despite its violent creation, it was held together by mutual self-interest.[21] The government was able to provide unity for a vast area through a combination of local autonomy and imperial authority.[28]
Unlike the great savannah empires, of which Oyo may be called a successor, there was little if any Muslim influence in the empire.[18] It is known that at least some Muslim officials were kept in Metropolitan Oyo,[39] and men capable of writing and calculating in Arabic were reported by French traders in 1787.[39]
Decline
The end of the 18th century marked the beginning of the Oyo Empire's downfall. In around 1789, Alaafin Abiodun is believed to have been killed by his son and successor, Awole.[30] A series of constitutional upheavals, dynastic intrigues and local particularism weakened the empire.[30] In 1796, Alaafin Awole was ousted by the government in an Illorin-centered revolt initiated by Afonja, the Are Ona Kakanfo. The revolt led to the secession of Ilorin, a Yoruba state that would would play a crucial role in the destruction of Oyo. At his rejection by the council, he is said to have cursed the empire as he prepared to commit suicide.[40] After firing arrows in all directions he proclaimed:
"My curse be on you and your disloyalty and your disobedience, so let your children disobey you. If you send them on an errand, let them never return to bring you word again. To all points I shot my arrows, you will be carried as slaves. My curse will cary to the sea and beyond the seas. Slaves will rule over you, and you their masters will become slaves. Broken calabash can be mended but not a broken dish; so let my words be irrevocable."
Loss of the Egbado Corridor
As Oyo tore itself apart via political intrigue, its vassals began taking advantage of the situation to press for independence. The Egba, under the leadership of Lishabi, massacred the Ilari stationed in their area and drove off an Oyo punitive force.[8]
The Dahomey Revolt
When Dahomey's King Gezo ascended the throne in 1818, he offered only a tiny piece of cloth and 2 bags of cowries to the Oyo tax collector saying that anything else would be disproportionate to Dahomey's wealth.[41] When four more envoys were sent from Oyo, Gezo had them beheaded.[41] An Oyo army was deployed and decisively defeated, ending Oyo's hegemony over Dahomey.[41] After gaining its independence, Dahomey began raiding the corridor.[11]
The Fulani Jihad
After Awole's rejection, Afonja, now master of Illorin, invited an itinerant Fulani scholar of Islam called Alim al-Salih into his ranks. By doing this, he hoped to secure the support of Yoruba Muslims (mainly slaves taking care of the Empire's horses) and volunteers from the Hausa-Fulani north in keeping Ilorin independent. Torn by internal struggle, Oyo could not defend itsefl against the Fulani.[40] Oyo-Ile was razed by the Fulani Empire and the empire collapsed in 1836,[42] once Afonja had been killed by the Fulani. Up to this day, the Illorin traditional ruler is an emir, whereas in the rest of Yoruba towns the kings are called oba or baale (Baale or Baba Onile meaning "father of the land" or "lord of the land").
Ago d'Oyo and Final Demise
After the destruction of Oyo-Ile, the capital was moved further south, to Ago d'Oyo. Alaafin Atiba sought to preserve what remained of Oyo by placing on Ibadan the duty of protecting the capital from the Ilorin in the north and northeast.[43] He also attempted to get the Ijaye to protect Oyo from the west against the Dahomeans.[43] The center of Yoruba power moved further south to Ibadan, a Yoruba war camp settled by Oyo commanders in 1830.[12] Oyo never regained its prominence in the region and became a protectorate of Great Britain in 1888. It further fragmented into warring factions and ceased to exist by 1896.[40] An increasing number of Yoruba war captives were subsequently transported to the coast for export as slaves to the new world (Brazil, Cuba, and Puerto Rico).
Aftermath
After fleeing the Fulani jihad, many concentrated around hills for military purposes. During the colonial period, the Yorubas were one of the most urbanized (living in city-like areas) group in Africa. About 22 % of the population lived in large areas with population exceeding 100,000 and over 50 % lived in cities of made up of 25,000 or more people. The index of urbanization in 1950 was close to that of the united state, excluding Ilorin. Old Oyo linked cities such as Ibadan, Osogbo, and Ogbomoso, which were some of the major cities that flourished after the collapse.[44]
