Dosso is a town in the south-west corner of Niger. It lies 130–140 km south-east of the capital Niamey at the junction of the main routes to Zinder and Benin. The seventh most populous town in Niger and the largest in Dosso Region, it had an official population during the 2001 census of 43,561. It is the capital of its region—which covers five departments in the southwestern corner of the nation, as well as of its own department: Dosso Department. The city itself lies at the center of its own Urban Commune.

Attractions in the town include the Djermakoy's palace and museum, nominated as a UNESCO World Heritage Site in 2006.

Dosso would be the interim terminus of a proposed railway from Parakou in Benin. An extension to the cpital would be a later stage.

Dosso is the seat of the Dosso kingdom, a Djerma chieftaincy which rose to dominate the entire Djerma region in the immediate pre-colonial period. The traditional ruler is styled Djermakoy or Zarmakoy of Dosso, an autochthonous title meaning literally "Djermas' owner"^{[citation needed]}: Djerma / Zarma being the name of the predominant ethnic group throughout southwest Niger.

Niger (French pronunciation: [niʒɛʁ], but occasionally pronounced as /niːˈʒɛər/ or ⁱ/ˈnaɪdʒər/), officially the Republic of Niger, is a landlocked country in Western Africa, named after the Niger River. It borders Nigeria and Benin to the south, Burkina Faso and Mali to the west, Algeria and Libya to the north and Chad to the east. Niger covers a land area of almost 1,270,000 km², making it the largest nation in West Africa, with over 80 percent of its land area covered by the Sahara desert. The country's predominantly Islamic population of just above 15,000,000 is mostly clustered in the far south and west of the nation. The capital city is Niamey, located in the far southwest corner of Niger.

Niger is a developing country, and consistently ranks as one of the lowest ranks of the United Nations' Human Development Index (HDI), 186th of 187 countries in 2011. Much of the non-desert portions of the country are threatened by periodic drought and desertification. The economy is concentrated around subsistence and some export agriculture clustered in the more fertile south, and the export of raw materials, especially uranium ore. Niger remains handicapped by its landlocked position, desert terrain, poor education and poverty of its people, lack of infrastructure, poor health care, and environmental degradation.

Hama Amadou (born 1950) is a Nigerien politician who was Prime Minister of Niger from 1995 to 1996 and again from 2000 to 2007. He was also Secretary-General of the National Movement for the Development of Society (MNSD-Nassara) from 1991 to 2001 and President of the MNSD-Nassara from 2001 to 2009. Amadou is from the Kurtey, a Fula sub-group, and was raised in the Tillaberi Region, in the Niger River valley, north of Niamey.

As a result of corruption allegations against his government, he was removed from office as Prime Minister through a 2007 no-confidence vote in the National Assembly. In 2008 he became the target of a corruption investigation which saw him arrested to face criminal charges at the Nigerien High Court of Justice and removed from his post as MNSD President.

Since April 2011, Amadou has been President of the National Assembly of Niger.

During the regime of Seyni Kountché, Amadou was Director-General of the Office of Radio Broadcasting and Television of Niger (ORTN) from 1983 to 1985 and became Director of the Cabinet in 1985. Following Kountché's death, Amadou was named Minister of Information under his successor, Ali Saibou, on July 15, 1988, serving until December 20, 1989.
