Askia Daoud responded by sending a large quantity of gold as a gift in an attempt to appease the sultan. Askia Ishaq II (1588–1591) ascended to power in a long dynastic struggle following the death of Askia Daoud. He would be the last ruler of the imperial Songhai empire. In 1590, al-Mansur took advantage of the recent civil strife in the empire and sent an army under the command of Judar Pasha to conquer the Songhai and to gain control of the Trans-Saharan trade routes. After the disastrous defeat at the Battle of Tondibi (1591), the Songhai Empire collapsed.
