Khalil Sultan, the son of Miran Shah, was already in Samarkand and declared himself king. Miran Shah wanted to support his son Khalil Sultan and for that purpose, he along with the Abu Bakr bin Miran Shah marched with their forces towards Samarkand. The only opposing force was Shahrukh Mirza in Herat who had marched till Amu Darya but turned back on hearing the news of Khalil Sultan's backup from Azerbaijan.
