Who showed the greatest growth in
Europe during the Industrial Revolution

Britain

Explanation:

Britain led the way with industrialization in the Industrial Revolution as population exploded due to improvements in Agriculture.

They surpassed the other European countries in the production of coal, railway and steam engines from the Industrial Revolution to around the mid 1800s.

This lead was however greatly reduced as the United States and other European countries caught up such that by the turn of the century, the British no longer dominated industralization.
