let's talk about Yoruba Civil War mostly known as Ogun Kiriji (Kiriji War). 1877-1893

The Kiriji War, an epic battle fought by the Yorubas for 16 years, is believed to be the World’s Longest Civil War by any ethnic group. The war, according to historians, was the fiercest tribal war among the Yoruba ethnic group of Southwest Nigeria and the Kiriji War

which ended almost 122 years ago led to the signing of a Peace Treaty on September 23, 1886.
How the War Started:
Ibadan, a relatively new establishment that had the honour of filling the oversized shoes of the former Oyo Empire as the protector of the

Yoruba nation against external attacks. But the military successes and wealth raked in by Ibadan in its military expeditions soon posed serious challenges. Like all global super-powers, Ibadan was said to embark on an expansionist programme that extended its reach to much of

Yorubaland. It started appointing District Officers known as ‘Ajeles’ to rule the conquered territories on its behalf. It did not take long for the ‘Ajeles’ to transform into despots. They became corrupt and power-drunk, demanding ridiculous homage and exorbitant tributes.

The Yoruba vassal states of Ijesha and Ekiti revolted and massacred the Ibadan-appointed ‘Ajeles’. They formed a confederacy called Ekiti Parapo (Ekiti Brotherhood) and declared their independence from Ibadan.
Ibadan knew the dire consequences of allowing such

action to go unpunished as it would encourage other conquered territories to declare independence.
Ibadan wanted a centralized political system, with a central economy, a command military structure, a central administration and a forcefully united Yoruba Nation,

while the other Yoruba subgroups wanted a decentralized structure, where all the federating units would be autonomous and would be able to plan their political future based on their own heritage. This led to the epic Yoruba war called the Kiriji War in 1877 when the Ibadan police

,navy, infantry and artillery soldiers, led by ‘General’ Obadoke Latoosa invaded the entire commonwealth of Yoruba nation, pummeled the sacred institutions, raided the markets and the deepest hinterlands and sought to proclaim a forcefully united Yoruba nation.

Kiriji war is the longest civil war by any ethnic group (1877 -1893) lasting 16years.
The Major Actors and Causalities:
Ibadan was led by its commander-in-chief, Aare Obadoke Latosa, while the Ekiti Parapo army was led by Fabunmi of Oke-Imesi.

The Ibadan army pitched their camp at Igbajo while the Ekiti Parapo camped at Imesi Ile.
Somewhere along the line, Saraibi Ogedengbe (famously known as Ogedengbe Agbogungboro), the Balogun of Ijeshaland, became the General/Commander-in-Chief of the Ekiti Parapo army,

and the appointment greatly influenced the turn of events, as Ogedengbe was a renowned military strategist.
The war got its name (Kiriji) from the thunderous sound “kiriiiiiiiiji”of the cannon guns which the Ekiti parapo purchased in large numbers.

The cannon gave them an advantage over the Ibadans. Ekiti Parapo enlisted several Yoruba tribes like: Igbomina, Akoko, Egbe, Kabba and the Oworro (a Yoruba sub-tribe in Lokoja, Kogi State). Lagos, Ijebu and Egba were said to have assisted Ekiti Parapo against Ibadan, seen by all

,as a common threat to the Yoruba commonwealth. Ilara Mokin in Ondo State was said to have been the headquarters of the Ekiti Parapo secret service. Several Yoruba towns, such as Osogun and Ijaiye, were wiped out in the course of the war. Igbajo barely escaped total destruction.

Eventually, Ibadan found itself fighting on five fronts. First, in the South against the Egba who confined their activities to raids and surprise attacks. Secondly, against the Ijebu, in the same south, who pitched a camp against them at Oru under Balogun. Thirdly, the main war

at Kiriji in the East, where their forces fought a long battle against the Ekiti and Ijesa (Ekiti-Parapo forces) under the command of Ogedengbe. Fourthly, at Offa in the north, where they faced the Ilorin Fulani who pitched their camp against the people of Offa (an ally of Ib)

and finally at IleIfe where the Ife people joined the alliance against them in 1882.
However, in spite of Ibadan's disadvantages in the war, these five forces could not effect its defeat. A state of stalemate was reached, from which only the intervention of an outside force

could redeem the whole Yoruba Nation. The war was put to an end by the British via the help of the Missionairies (In which Crowther's son et al played a part).Guns used during the war was purchased via the help of the Ijebus (Osuntinubuwa was a major supplier).

Peace treaty was signed in Imesi Ile. The burial site and where Balogun Latoosa was killed is still in Imesi Ile till date. Some of the guns, bullets, and charms used are still in Imesi Ile. You will be warned not to touch anything cos those charms are still active and potent,

even after 100 years plus.. There is an anthem for the end of the war in Yoruba. You can visit Imesi Ile to know more about the war.

Other notable generals include: Jogunomi, Aare Ago, Ajayi Ogboriefon, balogun Onafowokan etc.
