In Nigeria a civil war was going on. I was a correspondent covering the war. On a cloudy day I left Lagos. On the outskirts police were stopping all cars. They were searching the trunks, looking for weapons. They ripped open sacks of corn: could there be ammunition in that corn? Authority ended at the city line. The road leads through a green countryside of low hills covered with a close, thick bush. This is a laterite road, rust-coloured, with a treacherous uneven surface. These hills, this road and the villages along it are the country of the Yorubas, who inhabit south-western Nigeria. They constitute a quarter of Nigeria’s population. The heaven of the Yorubas is full of gods and their earth full of kings. The greatest god is called Oduduwa and he lives at a height higher than the stars, higher even than the sun. The kings, on the other hand, live close to the people. In every city and every village there is a king. In 1962 the Yorubas split into two camps. The overwhelming majority belongs to the UPGA (United Progressive Grand Alliance); an insignificant minority belongs to the NNDP (Nigerian National Democratic Party).
