Ulugh Beg
Ulugh Beg retreated to Balkh where he found that its governor, his oldest son Abdal-Latif Mirza, had rebelled against him. Another civil war ensued. Abdal-Latif recruited troops to meet his father's army on the banks of the Amu Darya river. However, Ulugh Beg was forced to retreat to Samarkand before any fighting took place, having heard news of turmoil in the city. Abdal-Latif soon reached Samarkand and Ulugh Beg involuntarily surrendered to his son. Abd-al-Latif released his father from custody, allowing him to make pilgrimage to Mecca. However, he ensured Ulugh Beg never reached his destination, having him, as well as his brother Abdal-Aziz assassinated in 1449.
