Answer:
Frequent battles for succession weakened the Songhai army.
Step-by-step explanation:
The Songhai Empire was weakened by leadership problems. During the Askia Dawud reign that lasted from 1549 to 1582, the Songhai Empire was in peace and stable, but when he died there was a round of disputes and a civil war for power. This led the empire to a period of decline and instability which contributed to the downfall of the empire.
