In the winter of that year, Ala al-Dawla became embroiled in a quarrel with Abdal-Latif, who had been stationed in Balkh as his father's governor. Ala al-Dawla launched a campaign against his cousin and plundered the region. Ulugh Beg used this as a pretext to attack and together with Abdal-Latif, he launched an invasion against his nephew in the spring of 1448.
