Nigeria Map

• The highest point in Nigeria is Chappal Waddi at 2,419 m (7,936 ft). The main rivers are the Niger and the Benue River which converge and empty into the Niger Delta, one of the world's largest river deltas and the location of a large area of Central African Mangroves.

• Nigeria is also an important center for biodiversity. It is widely believed that the areas surrounding Calabar, Cross River State, contain the world's largest diversity of butterflies. The drill monkey is only found in the wild in Southeast Nigeria and neighbouring Cameroon.

• Nigeria has a varied landscape. The far south is defined by its tropical rainforest climate, where annual rainfall is 60 to 80 inches (1,524 to 2,032 mm) a year. In the southeast stand the Obudu Plateau. Coastal plains are found in both the southwest and the southeast. This forest zone's most southerly portion is defined as salt water swamp, also known as a mangrove swamp because of the large amount of mangroves in the area. North of this is fresh water swamp, containing different vegetation from the salt water swamp, and north of that is rain forest.

• Nigeria's most expansive topographical region is that of the valleys of the Niger and Benue River valleys (which merge into each other and form a "y" shape). To the southwest of the Niger there is "rugged" highland, and to the southeast of the Benue are hills and mountains which forms the Mambilla Plateau,the highest Plateau in Nigeria.This plateau extends to the border with Cameroon, this montane land is part of the Bamenda Highlands in Cameroon. The area near the border with Cameroon close to the coast is rich rainforest and part of the Cross-Sanaga-Bioko coastal forests ecoregion, an important centre for biodiversity including the drill monkey which is only found in the wild in this area and across the border in Cameroon. It is widely believed that the areas surrounding Calabar, Cross River State, also in this forest, contain the world's largest diversity of butterflies. The area of southern Nigeria between the Niger and the Cross Rivers has seen its forest more or less disappear to be replaced by grassland (see Cross-Niger transition forests).

• Everything in between the far south and the far north, is savannah (insignificant tree cover, with grasses and flowers located between trees), and rainfall is between 20 and 60 inches (508 and 1,524 mm) per year. The savannah zone's three categories are Guinean forest-savanna mosaic, plains of tall grass which are interrupted by trees and the most common across the country: Sudan savannah, similar but with "shorter grasses and shorter trees; and Sahel savannah, comprised patches of grass and sand, found in the northeast. To the north is the Sahel with its almost desert-like climate, where rain is less than 20 inches (508 mm) per year and the Sahara Desert is encroaching. In the dry north-east corner of the country lies Lake Chad, which Nigeria shares with Niger, Chad and Cameroon.

• Upon gaining independence in 1960, Nigeria made the liberation and restoration of the dignity of Africa the centrepiece of its foreign policy and played a leading role in the fight against the apartheid regime in South Africa. One notable exception to the African focus of Nigeria's foreign policy was the close relationship the country enjoyed with Israel throughout the 1960s, with the latter country sponsoring and overseeing the construction of Nigeria's parliament buildings.

• Nigeria's foreign policy was soon tested in the 1970s after the country emerged united from its own civil war and quickly committed itself to the liberation struggles going on in the Southern Africa sub-region. Though Nigeria never sent an expeditionary force in that struggle, it offered more than rhetoric to the African National Congress (ANC) by taking a committed tough line with regard to the racist regime and their incursions in southern Africa, in addition to expediting large sums to aid anti-colonial struggles. Nigeria was also a founding member of the Organisation for African Unity (now the African Union), and has tremendous influence in West Africa and Africa on the whole. Nigeria has additionally founded regional cooperative efforts in West Africa, functioning as standard-bearer for ECOWAS and ECOMOG, economic and military organizations respectively.

• With this African-centred stance, Nigeria readily sent troops to the Congo at the behest of the United Nations shortly after independence (and has maintained membership since that time); Nigeria also supported several Pan African and pro-self government causes in the 1970s, including garnering support for Angola's MPLA, SWAPO in Namibia, and aiding anti-colonial struggles in Mozambique, and Zimbabwe (then Rhodesia) military and economically.

• Nigeria retains membership in the Non-Aligned Movement, and in late November 2006 organized an Africa-South America Summit in Abuja to promote what some attendees termed "South-South" linkages on a variety of fronts. Nigeria is also a member of the International Criminal Court, and the Commonwealth of Nations, from which it was temporarily expelled in 1995 under the Abacha regime.

• Nigeria has remained a key player in the international oil industry since the 1970s, and maintains membership in Organization of the Petroleum Exporting Countries OPEC which it joined in July, 1971. Its status as a major petroleum producer figures prominently in its sometimes vicissitudinous international relations with both developed countries, notably the United States and more recently China and developing countries, notably Ghana, Jamaica and Kenya.

• Millions of Nigerians have emigrated at times of economic hardship to Europe, North America and Australia among others. It is estimated that over a million Nigerians have emigrated to the United States and constitute the Nigerian American populace. Of such Diasporic communities include the "Egbe Omo Yoruba" society.

• Spaniard and Portuguese explorers were the first Europeans to begin trade in Nigeria in the port they named Lagos and in Calabar. The Europeans traded with the ethnicities of the coast and also negotiated a trade in slaves, to the detriment and profit of many Nigerian ethnicities. Consequently many of the citizens of the former slave nations of the British Empire are descended from a Nigerian ethnic group. Britain abolished its slave trade in 1807 and, following the Napoleonic Wars, established the West Africa Squadron in an attempt to halt the international traffic in slaves.

• In 1885, British claims to a West African sphere of influence received international recognition, and in the following year the Royal Niger Company was chartered under the leadership of Sir George Taubman Goldie. In 1900 the company's territory came under the control of the British government, which moved to consolidate its hold over the area of modern Nigeria. On January 1, 1901, Nigeria became a British protectorate, part of the British Empire, the foremost world power at the time. Many wars against subjugation had been fought by the states of what later became Nigeria against the British Empire in the late nineteenth and early twentieth century. Notably of those were the British Conquest of Benin in 1897 and the Anglo-Aro War from 1901—1902. The restraint or complete destruction of these states opened up the Niger area to British rule.

• In 1914, the Niger area was formally united as the Colony and Protectorate of Nigeria. Administratively, Nigeria remained divided into the northern and southern provinces and Lagos Colony. Western education and the development of a modern economy proceeded more rapidly in the south than in the north, with consequences felt in Nigeria's political life ever since. Slavery was not finally outlawed in northern Nigeria until 1936.

• Following World War II, in response to the growth of Nigerian nationalism and demands for independence, successive constitutions legislated by the British government moved Nigeria toward self-government on a representative and increasingly federal basis. By the middle of the 20th century, the great wave for independence was sweeping across Africa.

• Nigeria is divided into thirty-six states and one Federal Capital Territory, which are further sub-divided into 774 Local Government Areas (LGAs). The plethora of states, of which there were only three at independence, reflect the country's tumultuous history and the difficulties of managing such a heterogeneous national entity at all levels of government.

• Nigeria has six cities with a population of over 1 million people (from largest to smallest: Lagos, Kano, Ibadan, Kaduna, Port Harcourt, and Benin City). Lagos is the largest city in sub-Saharan Africa, with a population of over 8 million in its urban area alone. Population of Nigeria's cities over a million are listed below

• Nigeria is home to a substantial network of organized crime, active especially in drug trafficking. Nigerian criminal groups are heavily involved in drug trafficking, shipping heroin from Asian countries to Europe and America; and cocaine from South America to Europe and South Africa. . The various Nigerian Confraternities or "campus cults" are active in both organized crime and in political violence as well as providing a network of corruption within Nigeria. As confraternities have extensive connections with political and military figures, they offer excellent alumni networking opportunities. The Supreme Vikings Confraternity, for example, boasts that twelve members of the Rivers State House of Assembly are cult members. On lower levels of society, there are the "area boys", organized gangs mostly active in Lagos who specialize in mugging and small-scale drug dealing. According to official statistics, gang violence in Lagos resulted in 273 civilians and 84 policemen killed in the period of August 2000 to May 2001.

• Internationally, Nigeria is infamous for a crime dubbed 419, a type of advance fee fraud (named after Section 419 of the Nigerian Penal Code) along with the "Nigerian scam", a form of confidence trick practiced by individuals and criminal syndicates. In 2003, the Nigerian Economic and Financial Crimes Commission (or EFCC) was created to combat this and other forms of organized financial crime.

• There is also some Piracy in Nigeria, with attacks mainly directed at smaller ships shuttling employees and materials belonging to the oil companies with any involvement in oil exploration in the Niger Delta. From January 1, 2007 to October 29, 2007, twenty-six pirate attacks were recorded.
