Final answer:
The Union's blockade of Georgia's coast, which disrupted trade with Europe, directly contributed to the growth of Georgia's industrial economy during the Civil War as the South had to develop its own industrial capabilities and improve rail infrastructure.
Step-by-step explanation:
The growth of Georgia’s industrial economy during the Civil War can be attributed to the Union strategy of blockading Georgia’s coast and cutting off trade with Europe. This blockade severely limited the export of cotton and the import of manufactured goods, forcing the Confederacy to develop its own industry to sustain the war effort. As a result, Georgia, along with the rest of the South, had to improve its industrial capabilities, which included the expansion of railroad infrastructure to compensate for the loss of trade and to support the movement of goods and supplies within the Confederacy. The haphazard rail systems that previously existed were inadequate and necessitated a more unified and efficient structure, promoting industrial growth in the region.
