In the period between the 9th and 12th century, was it Islam's cultural influence, was it Islamic rulers, or was it the times that informed the technological, philosophical, and other innovations that continue to benefit contemporary society?

Well first of all, during the French Revolution the Reighn of Terror broke out. This was way worse than just having a war because it was uncontrollable, and many died even the wealthy and Louis XVI. France is not too big either, it is 248,573 mi², and 3/4 the size of Texas. During the American Revolution, the U.S had 13 states as many already know. So the population decrease was most likley greater in France than America. (BTW Napolean's rule did not help France either, in one incedent, he had 60,000 men go and fight Britain and only 10,000 came back).
