His only surviving heir was his son Ulugh Beg who was at that time viceroy of Central Asia at Samarkand.

Gawhar Shad and Abdal-Latif Mirza were with Shah Rukh when he died on his way back to Khurasan from Iran.

Abdal-Latif Mirza became the commander of his grandfather's army and in conjunction with his father Ulugh Beg began operations against his cousins.

As soon as Ulugh Beg heard of his father's death, he mobilized his forces and reached Amu Darya in order to take Balkh from his nephews.

Next operations though, would be difficult since the other nephews of Ulugh Beg were hardened warriors and sons of his now deceased yet famously able brother Baysunghur Mirza.
