The colony around Lagos was added in 1906, and the territory was officially renamed the Colony and Protectorate of Southern Nigeria.
In 1914, Southern Nigeria was joined with Northern Nigeria to form the single colony of Nigeria.
Postage stamps
Initially using the postage stamps of the Coast Protectorate, in March 1901 a set of nine values, depicting Queen Victoria in a 3/4 portrait, went on sale. The Queen was soon succeeded by her son Edward VII, necessitating a new issue of stamps, which came out in 1903. The design, a profile of the King, continued in use throughout his reign, with changes of watermark and paper. The 1p value was redrawn in 1910, and is distinguishable by the "1" in "1d" being thinner, while the "d" is taller and broader.
In 1912, the vignette was replaced with a portrait of George V, for a set of 12, with values ranging from 1/2p to 1 pound.
The lower values of these stamps are inexpensive, while the shilling values range up to US$100, with genuinely used stamps being worth more than unused. The rarest stamp is the 1-pound value of 1903, priced at around US$300 used.
Nigeria is in the tropics, a little north of the equator, and in the Sahel.
Nigeria is north of the Gulf of Guinea and south of the Sahara Desert.
Thirty-one percent of the land in Nigeria is used as arable land, three percent of it is used for permanent crops, 23 percent of the land is used as meadows and pastures, fifteen percent of the land is used as forest and woodland, and twenty-eight percent of the land is used for other things.
Nigeria borders Republic of Benin to the west, Chad and Cameroon in the east, Niger in the north and the Gulf of Guinea in the south.
Nigeria is divided roughly in three by the rivers Niger and Benue, which flow through the country from north-east and north-west to meet roughly in the centre of the country near the new capital city of Abuja.
Northern Nigeria was the location of half of all documented polio cases in 2003, but Muslim clerics have repeatedly inveighed against the vaccine as an effort by Westerners to sterilize young Nigerian Muslim girls.
