Nigeria has borders with Niger to the north, Chad (across Lake Chad) to the northeast, Cameroon to the east and Benin to the west. To the south, the Gulf of Guinea is indented by the Bight of Benin and the Bight of Biafra. The country’s topography and vegetation vary considerably. The coastal region is a low-lying area of lagoons, sandy beaches and mangrove swamps, which merges into an area of rainforest where palm trees grow to over 30m (100ft). From here, the landscape changes to savannah and open woodland, rising to the Central Jos Plateau at 1800m (6000ft). The northern part of the country is desert and semi-desert, marking the southern extent of the Sahara.

Republic since 1963. Gained independence from the UK in 1960. Military regime from 1983-1999. Head of State and Government: President Matthew Olusegun Obasanjo since 1999. Recent history: Olusegun Obasanjo and the People’s Democratic Party (PDP) came up for election again in April 2003. The election was a tense one since, if concluded successfully, this would be the first time since Independence that Nigeria had held two consecutive elections without military intervention. Despite allegations of widespread fraud and ballot-rigging, both the PDP and president Obasanjo were returned with comfortable majorities. (Obasanjo’s main opponent was yet another ex-military dictator, Mohammed Buhari.)
Under the provisions of the constitution announced by the Government in late 1998, executive power is vested in the President of the Republic. Legislative responsibilities are entrusted to the bicameral National Assembly, comprising the 360-member House of Representatives and the 109-member Senate. Members of both houses serve a four-year term.

Shaking hands with everyone is customary on meeting and departing. In Yorubaland, it is a sign of respect for women to curtsey when introduced and to enquire after relations, even if this is a first meeting. Unless the visitor knows someone well, it is unusual to be invited to a Nigerian’s home. Most entertaining, particularly in Lagos, takes place in clubs or restaurants. A small gift of appreciation is always welcome and business souvenirs bearing the company logo are also acceptable. Casual wear is suitable and a lightweight suit and tie are only necessary for businesspeople on formal meetings; on most other occasions men will not need to wear a jacket, although a tie might be expected. Women should dress modestly, and respect local customs regarding dress, particularly in the Muslim north. It is inadvisable for women to wear trousers. There are over 250 tribes in Nigeria, the principal groups being the Hausa in the north, the Ibo (or Igbo) in the southeast and the Yoruba in the southwest. The larger of the minor groups are the Fulani, Idoma, Igala, Igbirra, Kanuri, Tiv and Nupe in the north; the Efik, Ekoi, Ibibio and Ijaw in the east; and the Edo, Itsekiri, Ijaw and Urhobo in the west. A result of this ethnic variety is the diversity of art, dance forms, language, music, customs and crafts. Nigerians have a very strong sense of ethnic allegiance.
