Demographically, theYoruba people are the largest ethnic group in the state—particularly theAwori,Egba,Ijebu, andYewa subgroups, as well as smaller groups like theKetu,Ohori,Ilaje,Ikale and Anago.[6] Additionally, there are ethnic minorities of non-indigenous groups in urban areas and indigenousEgun people along the border with Benin. In terms of religion, the majority of the state's population are Christian with a significant Muslim minority.
Historically, parts of modern Ogun State were included in several kingdoms, including theBenin,Ijebu, andOyo states. In the late nineteenth century, British expeditions took control of the area and Abeokuta became a major center of missionary activity and education. During the early colonial period, the area was part of theSouthern Nigeria Protectorate, which later merged intocolonial Nigeria. After independence in 1960, the region was part of theWestern Region until the creation of Ogun State in 1976 from the oldWestern State.
Economically, Ogun State is a major industrial hub with a growing base of factories and companies, especially along theLagos–Ibadan Expressway corridor. Agriculture remains vital in rural areas, with key crops includingcassava,cocoa, and maize along with the indigenousOfada rice. The state is also known for its cultural heritage, crafts, and textile traditions along with the arts. Ogun ranks in themid-range inHuman Development Index and has theeighth highest GDP in the country.
In pre-colonial times, today's Ogun western portion which is now inhabited by the Egba and Yewa people belonged to thekingdom of Oyo, which sank into civil war mid 1800s. South of Ogun, on the tiny island ofLagos, the British had a naval base near which the town of the same name grew rapidly.
Until theBerlin Congo Conference in 1885, Great Britain had focused on a few strategically placed bases for its merchant fleet and navy, such as Lagos andCalabar, and was not interested in the communities developing there.
After the European colonial powers had staked out their spheres of interest 1885 inBerlin (these were only valid if another power had not previously brought the area in question under its control) theUnited Kingdom quickly expanded thusly its territory in the assigned Niger region. Today's Ogun became part of the "Protectorate of Lagos" (as opposed to theColony of Lagos; the border between these two is identical to the modern border betweenLagos State and Ogun State—inhabitants of a colony were treated as fully entitled subjects of the British crown, those in protectorates were not) in 1893 and later of the "Protectorate of Yorubaland", in 1906 of the "Protectorate of Southern Nigeria" and in 1914 of the whole of Nigeria. In 1899 it received a railway connection to Lagos, the "Boat Express" ran through Ogun toApapa and thus connected the region with the wider world. In 1899, it was several years earlier in this than other regions in West and Central Africa that were not connected to the coast.
In the 1930s, Ogun was a centre of theNigerian women's movement under the leadership ofFunmilayo Ransome-Kuti (Fela Kuti's mother). Democracy in colonial Nigeria after 1922 only existed in Lagos and Calabar; Nigerians could not participate politically elsewhere (seehere).
During the 1940s, food was strictly rationed in Nigeria. The transport of food from the more agrarian Ogun to the hungry metropolis of Lagos was severely penalized (Pullen Scheme, seehere).
In the first elections in Ogun, 1954, the semi-socialist "Action Group" (AG) underỌbáfẹ́mi Awólọ́wọ̀ became the strongest party in the Western Region, to which Ogun also belonged.
After independence in 1960, theYoruba region, and Ogun in particular, was engulfed in conflict between theỌbáfẹ́mi Awólọ́wọ̀ andSamuel Ládòkè Akíntọ́lá fractions of the AG party ("Operation Wetie", seehere). In July 1966, the then ruler of Nigeria,Johnson Agulyi-Ironsi, was assassinated inIbadan in the second coup of the year, which was the prelude to theBiafra War.
The state was formed on 3 February 1976 from part of the former "Western" state.
Ogun State borders the Republic ofBenin to the West for about 185 km,Oyo State andOsun State (for 84 km) to the North,Ondo State to the east,Lagos State to the South for about 283 km, and has 31.6 km of coastline on the Bight of Benin to the south, Araromi beach belongs to Irokun land in Ogun Waterside (Ijebu province) local government but insistently claimed by Ondo state due to the influx of Ilaje migrants from neighbouring communities and due to no attention given to this area by the Ogun state government.
Ogun has a Tropical wet and dry or savanna climate. The city's yearly average temperature is 29.34 °C (84.81 °F) and it is -0.12% lower than Nigeria's averages. Ogun receives about 141.58 millimeters (5.57 inches) of precipitation and has 224.18 rainy days (61.42% of the time) annually.[7]
The state has a very high concentration of industries (the second most industrialized afterLagos State) and has one of the lowest incidences ofextreme poverty (around 5% of the population against a national average of 31%) according toWorld Bank data from 2018.[8]
Ogún is also the name of the god (Orisha) for metalworking in the local Yoruba nature religion, similar to the GreekHephaestus or the Roman godVulcan (since the ancient world had trade relations with present-day Nigeria, this may not be entirely coincidental). The state lives up to this name by being the Nigerian centre for metalworking. Here are two examples:
Proforce manufactures armoured vehicles in Ode-Remo (25 km from Lagos), which are also sold to Europe.[16] Since 2008, the company has expanded its product range and also produces drones for the security sector.[17]
The wagon assembly plant inKajola is the only plant in West Africa that manufactures, maintains and repairs railway vehicles.[18][19]
Ogun also produces timber, ceramic products, bicycle tyres, carpets, adhesives and other products.
The State government is led by a democratically elected governor who works closely with members of the state's house of assembly. The capital city of the state is Abeokuta.[20]
The governor of the state is selected using a modified two-round system. To be elected in the first round, a candidate must receive the plurality of the vote and over 25% of the vote in at least two -third of the State local government Areas. If no candidate passes threshold, a second round will be held between the top candidate and the next candidate to have received a plurality of votes in the highest number of local government Areas.[20]
Ogun State is divided into three senatorial districts:
Ogun Central
Ogun Central consists mostly of the Egba that occupies six local governments: Abeokuta North (Akomoje), Abeokuta South (Ake), Ewekoro (Itori), Ifo (Ifo), Obafemi Owode (Owode ẹgba) and Odeda (Odeda).

The main ethnic groups in Ogun State are theẸgba,Ijebu, Remo,Yewa,Awori and a minority Egun people. There are also sub groups like the Ikale, the Ketu, the Ohori and the Anago.[23]
Ogun state has three federal secondary schools; Federal Government Girls' College, Sagamu[28] andFederal Government College, Odogbolu[29] and Federal Science and Technical College, Ijebu-Imushin.[30]
Ogun state has two Federal Universities; theFederal University of Agriculture, Abeokuta (FUNAAB)[31] andTai Solarin University of Education, Ijebu Ode and one Federal college of education, FCE Osiele (both at Odeda Local government area), one state government college of education, named after the late Nigerian educationist of international repute Augustus Taiwo Solarin in 1994 as Tai Solarin College of Education (TASCE[32]), (formerly known as Ogun State College of Education, Ijagun, Ijebu-Ode, one Federal Polytechnic, Ilaro). One is named after late Nigerian business mogul and winner of 12 June 1993 election, Basorun Moshood Kasimawo Olawale Abiola asMoshood Abiola Polytechnic (MAPOLY[33]), formerly known as Ogun State Polytechnic, Ojere, Abeokuta, Another Gateway Polytechnic Saapade,[34] Remo (GAPOSA), Abraham Adesanya Polytechnic[34] Ijebu-Igbo (Aapoly) (formerly known as 'The Polytechnic Ijebu-Igbo) it was name afterChief Abraham Aderibigbe Adesanya who was a Nigerian politician, lawyer and activist.
Ogun benefits from its proximity to the metropolis ofLagos and the newdeep-sea harbour and the newDangote refinery in Lekki (as of 2024). The planned airport Lagos-Epe will be located next to the border to the state of Ogun.
The terminus of the "Red Line" of the Lagos suburban railway is located in Agbado, which is part of the Lagos agglomeration but belongs to the state of Ogun in administrative terms. This is why the trains and carriages of Lagos State will be parked, cleaned and maintained in Ogun.[43]
The Ogun State Governor,Dapo Abiodun on 7 October 2025 inaugurated the first commercial flight of the Gateway International Airport inIlishan-Remo. The airport plans to fly passengers internationally.[44] An aircraft owned by the airlineValueJet, with registration number 5N-BXS and 90 passengers on board, departed the airport at 10:10 a.m. for Abuja as the first commercial flight to officially fly from the airport.[44]
