The Roman Empire survived more because it had economic stability. Its provinces produced food and other goods, carried out trade that brought wealth and also paid taxes. The empire was also well protected.
It was the main activity of the Southern economy and thwarted industrialization.
Explanation:
Before the Civil War, the North tended to have an economy that was increasingly industrial, it was not the case in the South. The economy in the South was much more based on agriculture, and it was thus much more rural(it had only three major cities, New Orleans, Vicksburgh and Atlanta) as well as the capital of the Confederacy Richmond Virginia.
On the eve of the Civil War, the South had 4 million slaves(the population was roughly 9 million people. Most white people did not own slaves(those who were slave owners had less than 10 slaves generally) and were poor farmers working on the lands left over by the planters. 80 % of the industries were in the North which explains why the South eventually lost the war.
The Civil War ravaged the South, nevertheless it made possible its industrialization by destroying the institution of slavery and the aristocracy which thrived on it. The exportation of cotton had brought great wealth to the south, but the wealth had been unevenly distributed.
The early 1800s is the pre-industrial era in Europe. The answer would be A. The Roman Empire because by the 1800s, the Roman Empire had a complicated network of coastal shipping and roads with large cities by the Mediterranean and they traded with India and China for goods.
