I want to know the answer to the following question:
How long did it take the Umayyad Caliphate to defeat the Visigoths?
All the background I'm provided with is that "Beginning in 711, the land that is now Portugal became part of the vast Umayyad Caliphate's empire of Damascus, which stretched from the Indus river in the Indian sub-continent (now Pakistan) up to the South of France, until its collapse in 750.". Is that enough to answer the question?
Answer: no
