In the late 19th century, the British and French agreed to partition the middle regions of the Niger River into British Nigeria and French Niger. In subsequent decades French administration spread until in 1922 Niger officially became a colony. Following independence from France in 1960, the country experienced single-party and military rule until 1991, when Gen. Ali SAIBOU was forced by public pressure to allow multiparty elections, which resulted in a democratic government in 1993. Political infighting brought the government to a standstill and in 1996 led to a coup by Col. Ibrahim BARE. In 1999, BARE was killed in a counter coup by military officers who restored democratic rule and held elections that brought Mamadou TANDJA to power in December of that year. TANDJA was reelected in 2004 and in 2009 spearheaded a constitutional amendment allowing him to extend his term as president. In February 2010, military officers led a coup that deposed TANDJA and suspended the constitution. ISSOUFOU Mahamadou was elected in April 2011 following the coup and reelected to a second term in early 2016. Niger is one of the poorest countries in the world with minimal government services and insufficient funds to develop its resource base, and is ranked last in the world on the United Nations Development Programme’s Human Development Index. The largely agrarian and subsistence-based economy is frequently disrupted by extended droughts common to the Sahel region of Africa. The Nigerien Government continues its attempts to diversify the economy through increased oil production and mining projects. A Tuareg rebellion emerged in 2007 and ended in 2009. Niger is facing increased security concerns on its borders from various external threats including insecurity in Libya, spillover from the conflict in Mali, and violent extremism in northeastern Nigeria.
