 Libya's adventure ended in disaster in 1987; the French-supported president, Hissène Habré, evoked a united response from Chadians of a kind never seen before and forced the Libyan army off Chadian soil.Habré consolidated his dictatorship through a power system that relied on corruption and violence with thousands of people estimated to have been killed under his rule.The president favoured his own Toubou ethnic group and discriminated against his former allies, the Zaghawa.
