Why did great Grimsby grow?

Great Grimsby grew primarily due to its strategic location as a port town on the Humber estuary, which facilitated trade and fishing. The establishment of the fishing industry in the 19th century, particularly herring and cod fishing, contributed significantly to its economic development. Additionally, the expansion of the railways in the late 1800s improved transport links, further enhancing Grimsby's role as a commercial hub. These factors combined led to population growth and the town's overall expansion.
