Answer:
Manchester
Step-by-step explanation:
Manchester was nicknamed "Cottonpolis" due to the importance of the textile industry. Cotton was imported from the the Southern states of the USA. New Orleans was the main agricultural port in the USA and cotton went from this city to Liverpool.
From Liverpool it went to manufactures mostly in Northern England, the most industrialized region of the UK. Great Britain was nicknamed the "workshop of the world" just like China today and was the biggest industrial power in the 1830s.
