A promised handover produced elected government, but the democratic interval remained reversible.
Jaafar Nimeiri’s sixteen-year rule ended in April 1985 after political unrest, economic crisis and renewed war in the south.
A Transitional Military Council led by Abdel Rahman Siwar al-Dahab took power, reopened party politics and promised to return authority to civilians. General elections were held in April 1986 and produced a civilian coalition government.
The civilian system struggled with war, factionalism and unresolved constitutional disputes. On 30 June 1989 officers led by Omar al-Bashir overthrew the government, abolished representative institutions and began another long period of authoritarian rule.
A successful transfer is not the same as democratic consolidation. The decisive test is whether constitutional institutions become strong enough that political actors cannot simply reopen the question of rule by force.
