Republic of Mali (modern)
Who & why: after the Mali Federation dissolves in August 1960, the former French Sudan declares itself the Republic of Mali on 22 September 1960 under President Modibo Keïta, taking its name from the medieval empire as a deliberate statement of pre-colonial heritage. Mali later passes through a long period of military and one-party rule (1968–91) before multiparty democracy is restored, and endures a serious Tuareg-led rebellion and jihadist insurgency in the north from 2012 onward — noted here factually as part of its recent history.
What it represents: the same green-gold-red vertical tricolor adopted for the 1959 Mali Federation, with the black kanaga figure (a stylized human form, an important Dogon cultural symbol) removed from the gold band in 1961 at Senegal's request, since the two countries' flags had become confusingly similar after the federation split.
