Mohammed II Tairab
One of the most capable of the monarchs during this period was Sultan Mohammed Terab, one of Ahmad Bukr's sons. He led a number of successful campaigns. In 1785/6 (AH 1200) he led an army against the Funj, but got no further than Omdurman. Here he was stopped by the Nile, and found no means of getting his army across the river. Unwilling to give up his project, Terab remained at Omdurman for months and the army began to grow disaffected. According to some stories Tayrab was poisoned by his wife at the instigation of disaffected chiefs, and the army returned to Darfur. While he tried to have his son succeed him, the throne instead went to his brother Abd al-Rahman.
