I want to know the answer to the following question:
When was Tajikistan under Ymayyads contorl?
All the background I'm provided with is that "Their arrival in Transoxania signaled a definitive shift from Iranian to Turkic predominance in Central Asia, but gradually the Kara-khanids became assimilated into the Perso-Arab Muslim culture of the region.". Is that enough to answer the question?
Answer: no
