I want to know the answer to the following question:
Between what years did Portugal establish a colonial and commercial empire?
All the background I'm provided with is that "The Portuguese language is derived from the Latin spoken by the romanized Pre-Roman peoples of the Iberian Peninsula around 2000 years ago—particularly the Celts, Tartessians, Lusitanians and Iberians.". Is that enough to answer the question?
Answer: no
