I want to know the answer to the following question:
When did cotton begin to be commercially grown in Egypt?
All the background I'm provided with is that "Though known since antiquity the commercial growing of cotton in Egypt only started in 1820's, following a Frenchman, by the name of M. Jumel, propositioning the then ruler, Mohamed Ali Pasha, that he could earn a substantial income by growing an extra-long staple Maho (Barbadence) cotton, in Lower Egypt, for the French market.". Is that enough to answer the question?
