Timur began his Persian campaign with Herat, capital of the Kartid dynasty. When Herat did not surrender he reduced the city to rubble and massacred most of its citizens; it remained in ruins until Shah Rukh ordered its reconstruction. Timur then sent a General to capture rebellious Kandahar. With the capture of Herat the Kartid kingdom surrendered and became vassals of Timur; it would later be annexed outright less than a decade later in 1389 by Timur's son Miran Shah.
