South West (Nigeria) in the context of "Oyo State"

Yoruba (US: /ˈjɔːrəbə/, UK: /ˈjɒrʊbə/; Yor. Èdè Yorùbá [èdè jōɾùbá]) is a Niger-Congo language that is spoken in West Africa, primarily in South West Nigeria, Benin, and parts of Togo. It is spoken by the Yoruba people. Yoruba speakers number roughly 50 million, including around 2 million second-language or L2 speakers. As a pluricentric language, it is primarily spoken in a dialectal area spanning Nigeria, Benin, and Togo with smaller migrated communities in Ivory Coast, Sierra Leone and Gambia.

Yoruba vocabulary is also used in African diaspora religions such as the Afro-Brazilian religions of Candomblé and Umbanda, the Caribbean religion of Santería in the form of the liturgical Lucumí language, and various Afro-American religions of North America. Among modern practitioners of these religions in the Americas, Yoruba is a liturgical language, as most of them are not fluent in it, yet they still use Yoruba words and phrases for songs or chants, which are rooted in cultural traditions. For such practitioners, the Yoruba lexicon is especially common for ritual purposes, and these modern manifestations have taken new forms that do not depend on vernacular fluency.

The Oyo Empire was a Yoruba empire in West Africa. It was located in present-day western Nigeria (including the South West zone, Benin Republic, and the western half of the North Central zone). The empire grew to become the largest Yoruba-speaking state through the organizational and administrative efforts of the Yoruba people, trade, as well as the military use of cavalry. The Oyo Empire was one of the most politically important states in Western Africa from the late-16th to the early 18th century and held sway not only over most of the other kingdoms in Yorubaland, but also over nearby African states, notably the Fon Kingdom of Dahomey in the modern Republic of Benin on its west.

Lagos State (Yoruba: Ìpínlẹ̀ Èkó, Gun: Ayìmátẹ̀n Awọnlìn tọ̀n) is a state in southwestern Nigeria. Of the 36 states, Lagos is the most populous state but has the smallest landmass in Nigeria. Bounded to the south by the Bight of Benin and to the west by the international border with the Republic of Benin, Lagos State borders Ogun State to the north and east, making it the only Nigerian state to border only one other state. Named for the city of Lagos — the most populous city in Africa — the state was formed from the Western Region and the former Federal Capital Territory on 27 May 1967.

Geographically, Lagos State is dominated by bodies of water with nearly a quarter of the state's area being lagoons, creeks, and rivers. The largest of these bodies are the Lagos and Lekki lagoons in the state's interior with the Ogun and Osun rivers flowing into them. Many other rivers and creeks flow throughout the state and serve as vital means of transportation for people and goods. On land, non-urbanized areas are within the tropical Nigerian lowland forests ecoregion with natural areas containing threatened populations of mona monkey, tree pangolin, and hooded vulture along with a transitory population of African forest elephants. Offshore, the state is also biodiverse as there are large fish populations along with African manatees and crocodiles.

AbeokutaListen is the capital city of Ogun State, which is located in southwestern Nigeria. It is situated on the east bank of the Ogun River, near a group of rocky outcrops in a wooded savanna; 77 kilometres (48 mi) north of Lagos by railway, or 130 kilometres (81 mi) by water. As of 2006, Abeokuta and the surrounding area had a population of 449,088.

The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. It is located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state (Ondo) from South West geopolitical zone and two states (Abia and Imo) from South East geopolitical zone.

The Niger Delta is a very densely populated region sometimes called the Oil Rivers because it was once a major producer of palm oil. The area was the British Oil Rivers Protectorate from 1885 until 1893, when it was expanded and became the Niger Coast Protectorate.

Ogun StateListen (Yoruba: Ìpínlẹ̀ Ògùn [ìk͡pĩ́lɛ̀ ògũ̀]) is a state in southwestern Nigeria. It is bordered to the south by Lagos State and the Bight of Benin, to the east by Ondo State, and to the north by Oyo and Osun states while its western border forms part of the national border with the Republic of Benin. The capital and largest city is Abeokuta, and the state is divided into 20 local government areas.

Of the 36 states in the country, Ogun is the 24th largest in area but among the top fifteen most populous, with an estimated population of about 6.4 million as of 2020. Geographically, the state lies primarily in the tropical Nigerian lowland forests ecoregion, although parts of the state's north transition into the Guinean forest–savanna mosaic and some of the coastal south reach the Central African mangrove ecoregion. The Ogun and Yewa rivers are the state's major waterways while the Omo Forest Reserve in the southeastern part of the state is one of the most important conservation areas in the country—home to a variety of bird species along with some of Nigeria's last remaining Nigeria-Cameroon chimpanzee and African forest elephant populations.

Ekiti listen(Yoruba: Ìpínlẹ̀ Èkìtì) is a state in southwestern Nigeria, bordered to the North by Kwara State for 61 km, to the Northeast by Kogi State for 92 km, to the South and Southeast by Ondo State, and to the West by Osun State for 84 km. Named for the Ekiti people—the Yoruba subgroup that makes up the majority of the state's population—Ekiti State was carved out from a part of Ondo State in 1996 and has its capital as the city of Ado-Ekiti.

One of the smallest and most educated states with the highest number of professors in Nigeria, Ekiti is the 31st largest in the area and 30th most populous with an estimated population of nearly 3.5 million as of 2022. Geographically, the state is divided between the Nigerian lowland forests in most of the state and the drier Guinean forest–savanna mosaic in the north. Among the state's nature are false acraeas, mona monkey, forest buffalo, and grey parrot populations along with one of the last remaining Nigeria-Cameroon chimpanzee populations with a troop of about 20 chimpanzees in the heavily threatened Ise Forest Reserve. In March 2022, Ekiti State became the first state in Nigeria to adopt a state tree as one of its official symbols. On World Forest Day 2022, Governor Kayode Fayemi announced that Obeche (Triplochiton scleroxylon) had been chosen as State Tree owing to its local prominence and environmental, economic and cultural significance.

OsunListen (/ˈoʊʃuːn/ OH-shoon; Yoruba: Ìpínlẹ̀ Ọ̀ṣun [ìk͡pĩ́lɛ̀ ɔ̀ʃũ̄]), is a state in southwestern Nigeria; bounded to the east by Ekiti and Ondo states for 84 km and for 78 km respectively, to the north by Kwara State for 73 km, to the south by Ogun State for 84 km and to the west by Oyo State, mostly across the River Osun. Named for the River Osun—a vital river which flows through the state—the state was formed from the southeast of Oyo State on 27 August 1991 and has its capital as the city of Osogbo.

Of the 36 states of Nigeria, Osun is the ninth smallest in area and 25th most populous state with an estimated population of about 4.7 million as of 2016. Geographically, the state is divided between the Nigerian lowland forests in most of the state and the drier Guinean forest–savanna mosaic in the north. The major geographical features are rivers including the state's namesake, the River Osun which bisects the state's interior before forming much of the state's southwestern border with Oyo State and flowing south. Other important rivers are the Erinle and Oba rivers, both Osun tributaries which flow from the north before meeting the Osun along the southwestern border. Among the state's fauna are mona monkey, common kestrel, purple heron, and royal antelope, along with some of Nigeria's last remaining Nigeria-Cameroon chimpanzee and African forest elephant which inhabit the heavily threatened forests along the southern borders with Ondo and Ogun states.
