I want to know the answer to the following question:
In what century had mills such as gristmills and sawmills dominate the Islamic world?
All the background I'm provided with is that "The industrial uses of watermills in the Islamic world date back to the 7th century, while horizontal-wheeled and vertical-wheeled water mills were both in widespread use since at least the 9th century.". Is that enough to answer the question?
