Anti-government protests in 1991 led to a coup, a transitional government, and a new constitution. Opposition to the corrupt and dictatorial regime of General Moussa Traoré grew during the 1980s. During this time strict programs, imposed to satisfy demands of the International Monetary Fund, brought increased hardship upon the country's population, while elites close to the government supposedly lived in growing wealth. Peaceful student protests in January 1991 were brutally suppressed, with mass arrests and torture of leaders and participants. Scattered acts of rioting and vandalism of public buildings followed, but most actions by the dissidents remained nonviolent.
