Answer:
In the 1840s, 50s and 60s newly established widespread railroad systems finally linked the Northeast and Midwest into an integrated commercial and industrial unit.
As a result, Midwestern industries of coal, iron, food processing, lumber, furniture and glass increased sharply while Northeaster industries like clocks, textiles, and shoes grew to a global scale.
Due to all of this Northern and Midwestern industrialization, the South became a supplier of the raw materials necessary for industrialization, instead of developing its own industries.
Explanation:
In the early 1800s, the Northeast started to develop strong regional economies.
By the 1820s, rural New England and the Middle Atlantic became heavily industrialized with clocks, textiles, shoes and cast-iron stoves becoming the predominant industries there.
As factories produced more goods, transporting those goods became important. In the 1820s and 30s, factories began trying to find new ways to reach consumers in the West since transportation to this region at the time was virtually nonexistent.
To help reach these Western consumers, the Erie Canal, which cut across the state of New York and created a water route from the Atlantic Ocean to the Great Lakes, was completed in 1825. Shipping goods through the canal cut shipping costs to a fraction of what it used to be via ground transportation.
After the western steamboat was developed, around 1814, by Henry Shreve and Daniel French, it finally allowed for large cargo loads to be transported upstream even in shallow water, which helped spur industrialization in the West. Within a decade the region’s great grain, lumber, and meat animal enterprises were centralizing in Cincinnati, as a tight-knit riverine economy took shape within the Ohio, Missouri, and Mississippi valleys. Cincinnati invented the meatpacking ‘disassembly’ line later made famous by Chicago, and Cincinnati brothers-in-law Proctor and Gamble were innovators in America’s first chemical industry.
In 1837, the Federal government completed a 620-mile national road from Maryland to Illinois in an effort to help manufacturers transport goods westward.
The South, in the meantime, slipped into the position of an internal colony, exploiting its slaves and being exploited in turn by the Northeast and Midwest. Boston and New York controlled much of the shipping, insurance, and brokerage earnings from the cotton trade, while the earnings left over went for Midwestern food, tools, and engines, shipped down the Mississippi and its branches.
In 1850, the second industrial revolution, which saw the rise in electricity, petroleum and steel, began in the United States and then spread to Europe and the rest of the world.
