Bayelsa is a state in the South South region of Nigeria, located in the core of the Niger Delta. Bayelsa State was created in 1996 and was carved out from Rivers State, making it one of the newest states in the federation. The capital, Yenagoa, is susceptible to high risk of annual flooding. It shares a boundary with Rivers State to the east and Delta State to the north across the Niger River for 17 km and the Forçados River for 198 km, with the waters of the Atlantic Ocean dominating its southern borders. It has a total area of . The state comprises eight local government areas: Ekeremor, Kolokuma/Opokuma, Yenagoa, Nembe, Ogbia, Sagbama, Brass and Southern Ijaw. The state is the smallest in Nigeria by population as of the 2006 census. Being in the Niger Delta, Bayelsa State has a riverine and estuarine setting, with bodies of water within the state preventing the development of significant road infrastructure. The languages of the Ijaw are widely spoken in Bayelsa State, along with Isoko and Urhobo. The state is the primary home for the Ijaw's their ancestral home. The state is also the ancestral home of the Urhobo people in the Sagbama local government area. As a state in the oil-rich Niger Delta, Bayelsa State's economy is dominated by the petroleum industry. The state is the site of Oloibiri Oilfield, where oil was first discovered in Nigeria, and as of 2015 was estimated to produce 30-40% of the country's oil. The state has the largest gas reservoir (18 trillion cubic feet) in Nigeria. Though being the site of one of the largest crude oil and natural gas deposits in the country contributes to local economic development, the state remains plagued by rampant poverty as well as pollution stemming from oil spills. Douye Diri is the governor of Bayelsa State, while Lawrence Ewhrudjakpo is the deputy governor. During the 20th century, demands a new, majority-Ijaw state to be drawn in the Niger Delta Region became common. Between 1941 and 1956, numerous Ijaw nationalist organizations supportive of an Ijaw-majority state in Southern Nigeria were founded.
