I need to know how the industrial revolution would be an example of Nationalism during the 19th century, and how Nationalism had an impact/effect on the Industrial Revolution.

Nationalism influenced it mostly in Great Britain, since it was the leading industrial power at first, and influenced other nations to step it up. The people were determined, as well as the government, to improve the standard of living and to keep their country as a major power, which then influenced factories to work harder and develop all the commodities to improve trade.

sorry its so spread out and vague, but i hope it helps!
