Sonni (Sunni) ʿAlī becomes ruler at Gao (c. 1464), initiating the major imperial expansion phase of Songhai in the Middle Niger region.
Songhai forces under Sunni Ali seize Timbuktu from Tuareg control (commonly dated 1468/1469), bringing a key Saharan-trade and scholarly center under Songhai authority.
After a multi-year siege, Sunni Ali captures Djenné (often dated 1473), tightening Songhai control over the Inland Niger Delta’s commercial routes.
Sunni Ali dies in 1492 and is succeeded by Sunni Baru, setting up a contested transition that soon ends the Sonni dynasty’s rule.
In 1493, Muhammad (later Askia Muhammad I) defeats Sunni Baru—commonly associated with the Battle of Anfao—and begins the Askia dynasty, aligning the regime more publicly with Islamic legitimacy.
Askia Muhammad I undertakes the pilgrimage (hajj) to Mecca (often dated 1496, returning about 1497/1498). The journey bolsters his prestige and supports his wider program of Islamic patronage and governance.
Askia Muhammad I reorganizes Songhai into provinces under appointed governors and builds a more structured state apparatus, including a standing army and war-canoe fleet—strengthening imperial control over confederated provinces and trade corridors.
In 1528, Askia Muhammad I is overthrown by his son Askia Musa, triggering a period of dynastic conflict that weakens central authority in the decades that follow.
Askia Muhammad I dies in 1538 at Gao, after years of political turmoil among his successors; his rule remains central to Songhai’s administrative model and later historical memory.
Askia Daoud rules from 1549 to 1582, a period often described as renewed stability and prosperity after earlier succession struggles, with Songhai retaining wide influence across the Niger bend and Saharan trade networks.
Following Askia Daoud’s death (1582) and the later death of Askia Muhammad al-Hajj (1586), intensified succession conflict further destabilizes the empire on the eve of external invasion.
On 1591-03-13, Saadian Moroccan forces under Judar Pasha defeat Songhai under Askia Ishaq II at Tondibi, a decisive gunpowder-era battle that breaks Songhai’s imperial military power.
After Tondibi in 1591, Saadian forces move through the Niger bend and take major centers including Gao, Timbuktu, and Djenné, undermining Songhai’s capacity to coordinate its confederated provinces and trade taxation.
By 1591, effective imperial rule collapses; power splinters among successor polities and regional authorities (including continued Songhai leadership traditions further downriver), marking the end of Songhai as a unified empire.
