Aouzou Strip
The Aouzou Strip قطاع أوزو (alternatively, Aozou Strip) is a strip of land in northern Chad which lies along the border with Libya, extending south to a depth of about 100 kilometers into Chad's Bourkou-Ennedi-Tibesti Region.
Claimed to be rich with uranium deposits, a dispute over the control of this area with Libya led to a war between the two countries. In 1973, Libya engaged in military operations in the Aouzou Strip to gain access to minerals and to use it as a base of influence in Chadian politics. Libya argued that the territory was inhabited by indigenous people who owed allegiance to the Senoussi Order and subsequently to the Ottoman Empire, and that this title had been inherited by Libya. It also supported its claim with an unratified 1935 treaty between France and Italy, the colonial powers of Chad and Libya, respectively. After consolidating its hold on the strip, Libya annexed it in 1976.
The frontier claimed by the Chadian government was based on a 1955 treaty between France and Libya, which, in turn, referred back to an 1899 agreement between Great Britain and France about "spheres of influence". Despite other differences, this was one position on which all Chadian political parties and factions were able to agree.
Chadian forces were able to force the Libyans to retreat from the Aouzou Strip in 1987. A cease-fire between Chad and Libya held from 1987 to 1988, followed by unsuccessful negotiations over the next several years, leading finally to the 1994 International Court of Justice decision granting Chad sovereignty over the Aouzou strip, which ended Libyan occupation.
