Oyo State in the context of "Western State (Nigeria)"

Kwara (Yoruba: Ìpínlẹ̀ Kwárà) is a state in Western Nigeria, bordered to the east by Kogi State, to the north by Niger State, and to the south by Ekiti, Osun, and Oyo states, while its western border makes up part of the international border with Benin. Its capital is the city of Ilorin and the state has 16 local government areas.

Of the 36 states of Nigeria, Kwara is the ninth largest in area but the sixth least populous with an estimated population of about 3.2 million as of 2016. Geographically, Kwara is split between the West Sudanian savanna in the east and the Guinean forest–savanna mosaic ecoregion in the rest of the state. Important geographic features include rivers with the Niger flowing along the northern border into Lake Jeba before continuing as the border while the Awun, Asa, Aluko, and Oyun rivers flow through the interior. In the far northwest of the state is the Borgu section of the Kainji National Park, a large national park that contains populations of grey heron, kob, hippopotamus, African bush elephant, olive baboon, and roan antelope, along with some of the last remaining West African lions on earth. In the far southwest, a small part of the Old Oyo National Park contains crowned eagle, martial eagle, African buffalo, oribi, and patas monkey populations.

The South West (often hyphenated to the South-West) is one of the six geopolitical zones of Nigeria representing both a geographic and political region of the country's southwest. It comprises six states — Ekiti, Lagos, Ogun, Ondo, Osun, and Oyo.

The zone stretches along the Atlantic seaboard from the international border with Benin Republic in the west to the South South in the east with the North Central to the north. The South West is split with the Central African mangroves in the coastal far south while the major inland ecoregions are the Nigerian lowland forests ecoregion in the south and east along with the Guinean forest–savanna mosaic ecoregion in the drier northwest. The weather conditions vary between Nigeria's two, distinctive seasons; the rainy season (March - November) and the dry season named the Harmattan (from November - February). The Harmattan is a dry and dusty northeasterly trade wind (of the same name), which blows from the Sahara over West Africa into the Gulf of Guinea. During this season, the wind transports the eponymous Harmattan dust, particles of fine Saharan sand.

The Yorùbá religion (Yoruba: Ìṣẹ̀ṣe [ìʃɛ̀ʃē]), West African Orisa (Òrìṣà [òɾìʃà]), or Isese (Ìṣẹ̀ṣe), comprises the traditional religious and spiritual concepts and practice of the Yoruba people. Its homeland is in present-day Southwestern Nigeria and Southern Benin, which comprises the majority of the states of; Oyo, Ogun, Osun, Ondo, Ekiti, Kwara, Lagos and parts of Kogi in Nigeria, the Departments of; Collines, Oueme, Plateau in Benin, and the adjoining parts of central Togo, commonly known as Yorubaland (Yoruba: Ilẹ̀ Káàárọ̀-Oòjíire). It has become the largest indigenous African tradition / belief system in the world with several million adherents worldwide.

It shares some parallels with the Vodun practised by the neighbouring Fon and Ewe peoples to its west and with the religion of the Edo people to its east. Yorùbá religion is the basis for several religions in the New World, notably Santería, Umbanda, Trinidad Orisha, and Candomblé. Yorùbá religious beliefs are part of Ìtàn (history), the total complex of songs, histories, stories, and other cultural concepts which make up the Yorùbá society.

IbadanListen (UK: /ɪˈbædən/, US: /ɪˈbɑːdən/; Yoruba: Ìbàdàn [ì.bà.dã̀]) is the capital and most populous city of Oyo State, in Nigeria. It is the third largest city by population in Nigeria with a total population of roughly 3,649,000 as of 2021, and nearly 2 million within its metropolitan area. At 3,080 square kilometres it is the country's largest city by land area. At the time of Nigeria's independence in 1960, Ibadan was the largest and most populous city in the country, and the second-most populous in Africa behind Cairo. Ibadan is ranked one of the fastest-growing cities in sub-Saharan Africa, according to the UN Human Settlements Program (2022). It is also ranked third in West Africa in the tech startups index. Ibadan joined the UNESCO Global Network of Learning Cities in 2016. During the 19th century, Ibadan was the capital of the Ibadan Republic, one of the most powerful states of contemporary Yorubaland.

Ibadan is located in southwestern Nigeria, 120 kilometres (75 mi) inland northeast of Lagos and 440 kilometres (270 mi) southwest of Abuja, the federal capital. It is a prominent transit point between the coastal region and areas in the hinterland of the country as well as one of Nigeria's most important commercial and research centres. Ibadan was the administrative centre of the old Western Region since the early days of British colonial rule, and parts of the city's ancient protective walls still stand to this day. The principal inhabitants of the city are the Yoruba people, as well as various communities (notably Igbo, Hausa, Edo, Ebira, Igede, Igala, Ibibio etc.) from other parts of the country.

The Law of Nigeria consists of courts, offences, and various types of laws. Nigeria has its own constitution which was established on 29 May 1999. The Constitution of Nigeria is the supreme law of the country. There are four distinct legal systems in Nigeria, which include English law, Common law, Customary law, and Sharia Law. English law in Nigeria is derived from the colonial Nigeria, while common law is a development from its post-colonial independence.

Customary law is derived from indigenous traditional norms and cultural practices, including the dispute resolution meetings of pre-colonial Yoruba land secret societies and the Èkpè and Okónkò of Igboland and Ibibioland. Sharia Law (also known as Islamic Law) used to be used only in Northern Nigeria, where Islam is the predominant religion. It is also being used in Lagos State, Oyo State, Kwara State, Ogun State, and Osun State by Muslims. The country has a judicial branch, the highest court of which is the Supreme Court of Nigeria.

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.

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.

The Old Oyo National Park is one of the national parks of Nigeria, located across northern Oyo State and southern Kwara State, Nigeria.The park is 2,512 km of land in northern Oyo state, south west Nigeria, at latitude 8° 15’ and 9° 00’N and longitude 3° 35’ and 4° 42’ E. The location has inevitably placed the park at a vantage position of abundance land area as well as diverse wildlife and cultural/historical settings. Eleven local government areas out of which ten fall within Oyo State and one in Kwara State surrounds it. The Administrative Head Office is located in Oyo, Isokun area along Oyo-Iseyin road, where necessary information and booking could be made. The landscaping and organized space within the large yard has made the facility very endearing to the public.It is rich in plant and animal resources including buffaloes, bushbuck and a variety of birds. The park is easily accessible from southwestern and northwestern Nigeria. The nearest cities and towns adjoining Old Oyo National Park include Saki, Iseyin, Igboho, Sepeteri, Tede, Kishi, and Igbeti, which have their own commercial and cultural attractions for tourism.
