The two most dynamic and fastest-growing industries in Britain during the first phase of industrialisation up to the 1840s were cotton and metals.
Cotton was the leading sector in this phase. Its production boomed rapidly — raw cotton imports rose from 2.5 million pounds in 1760 to 22 million pounds by 1787. After the 1840s, the iron and steel industry took the lead, especially with the rapid expansion of railways, which greatly increased demand for these metals.
