Which power center led the world in industrial production in the mid 19th century?

In the mid-19th century, Britain emerged as the leading power center in industrial production, primarily due to its early adoption of the Industrial Revolution. The country benefited from abundant coal and iron resources, a strong naval presence for trade, and a growing network of railways and factories. This industrial dominance allowed Britain to produce textiles, machinery, and other goods at an unprecedented scale, solidifying its position as the world's foremost industrial power during that period.
