Niamey. Population: 890,000 (UN estimate 2003).

Niger has borders with Libya and Algeria to the north, Chad to the east, Nigeria and Benin to the south, and Mali and Burkina Faso to the west. The capital, Niamey, stands on the north bank of the Niger River and has long been a major trading centre on this important navigable waterway. The river meanders for 500km (300 miles) through the southwestern corner of the country.

To the east is a band of semi-arid bush country along the border with Nigeria, shrinking by 20km (12 miles) every year as over-grazing claims more land for the Ténéré Desert, which already occupies over half of Niger. This desert is divided by a range of low mountains, Aïr ou Azbine, in the eastern foothills of which lies the city of Agadez. Surrounded by green valleys and hot springs amid semi-desert, this regional capital is still a major terminus for Saharan caravans. The desert to the west of the mountains is a stony plain hosting seasonal pastures; to the north and west are mostly vast expanses of sand. There is arable land beside Lake Chad in the extreme southeastern corner of the country.

The Hausa people live along the border with Nigeria and most are farmers. The Songhai and Djerma people live in the Niger valley and exist by farming and fishing. The nomadic Fulani have spread all over the Sahel. The robed and veiled Tuaregs once dominated the southern cities; the few who remain are camel herders and caravanners on the Saharan routes. The Manga (or Kanun) live near Lake Chad and are well known for their colourful ceremonies in which pipes and drums accompany slow, stately dancing.

Republic since 1960.

President Mamadou Tandja since 1999.

Acting Prime Minister Albade Abouba since 2009.

Alleged attempts by Iraq to procure uranium from Niger were the subject of controversy in 2003. Mamadou Tandja won a second (and final) term in the December 2004 presidential elections. While he has been praised for bringing stability to Niger, the country remains one of the poorest and least developed in the world. Its susceptibility to drought and famine was again exposed in 2005 and 2006, leaving the country in a weakened state.

The official languages are French and Arabic. Also spoken are Hausa (by half of the population), Djerma, Fulani, Manga, Zarma and Tuareg dialects.
