Iran remained divided until the arrival of
Timur (1370–1405), who was of
Turkified Mongol origin and the founder of
Timurid dynasty. Like its predecessors, the
Timurid Empire was also part of the Persianate world. After establishing a power base in Transoxiana, Timur invaded Iran in 1381 and eventually conquered most of it. Timur's campaigns were known for their brutality; many people were slaughtered and several cities were destroyed.
