did songhai conquer mali before sundiata took over ghana

No, Songhai did not conquer Mali before Sundiata took over Ghana. Mali was established as a powerful empire around the 13th century by Sundiata Keita, who is also known as Sundiata Keita. Sundiata expanded the Mali Empire through conquest and diplomacy, but Songhai did not conquer Mali until the early 15th century, after the decline of the Mali Empire.
