Edo State is an inland state in central southern Nigeria. Its capital is Benin City. It is bounded in the north and east by Kogi State, in the south by Delta State and in the west by Ondo State.

Edo State was formed on 27 August 1991 when Bendel State was split into Edo and Delta States.

The 1992 gubernatorial election, pitting John Odigie Oyegun (the SDP candidate) against Lucky Igbinedion (the NRC candidate) was annulled on 4 February of that year by the electoral tribunal. Among Igbinedion's claims were that the Oba of Benin and one of his chiefs, Nosakhare Isekhure, unfairly supported Oyegun. Oyegun's victory was upheld on 18 March 1992.

On 20 March 2008, an election tribunal nullified the election of Oserheimen Osunbor People's Democratic Party,(PDP) and declared erstwhile labour leader Comrade Adams Oshiomhole of the Action Congress as the winner. The decision was based on several voting irregularities.

Edo State consists of the following Local Government Areas:

The major first languages spoken in the state are Edo, Esan, Owan, Etsako, Akoko-Edo, Orhionmwon and Okpamheri. Edo State is home to several ethnicities, among them the Bini, Esan, Afemai, Ora, Akoko-Edo, Igbanke, Emai and Ijaw.

Edo (江戸, Edo^?, literally "bay-entrance" or "estuary"), also romanized as Yedo or Yeddo, is the former name of the Japanese capital Tokyo. It was seat of power for the Tokugawa shogunate, which ruled Japan from 1603 to 1868. During this period it grew to become one of the largest cities in the world and home to an urban culture centered on the notion of a "floating world".

From the establishment of the Tokugawa bakufu's headquarters at Edo, although Kyoto remained the formal capital of the country the de facto capital was now Edo; it was the center of political power. Edo grew from what had been a small, little-known fishing village in 1457 to a metropolis with an estimated population of 1,000,000 by 1721 (the largest city in the world at the time).

Edo was repeatedly devastated by fires, with the Great Fire of Meireki in 1657 (in which an estimated 100,000 people died) the most disastrous. During the Edo period there were about 100 fires (most begun by accident, often quickly escalating and spreading through neighbourhoods of wooden machiya which were heated with charcoal fires. Between 1600 and 1945, Edo/Tokyo was leveled every 25–50 years or so by fire, earthquakes, tsunami, volcanic eruptions or war.
