Answer:Chinggis Khan
From the 6th to the 13th century it grew into a city more populous than it is today, changing hands every couple of centuries – Western Turks, Arabs, Persian Samanids, Karakhanids, Seljuq Turks, Mongolian Karakitay and Khorezmshah have all ruled here – before being obliterated by Chinggis Khan in 1220.
Explanation:
The 16th century saw the origins of the scientific revolution in Europe especially centred in the Rennaisance in Italy. Economically this was a response to the burgeoning trade in the Mediterranean between Italian ports and Middle Eastern and North African countries and under the tutelage of rich powerful families like the Medicis and also the transition from feudalism of the Middle Ages to the nascent capitalism in Europe. The geocentric theory of the earth was challenged by Galileo (Italian )and Copernicus (Polish) as a result of the intellectual foment brought in with capitalism. In mining, Georgius Agricola, who was trained as a physician began first-hand investigation of underground mines in the Erzgebirge Mts of Bohemia and wrote the treatise on this called De Re Metallica which was the authority on such mining/milling techniques for 200 years after. This was made possible by the personal investigation of the mines and discussion with the miners and mine managers which was a big break from the classical scholars who often merely speculated on things.
The period referred to here is called the enlightenment age
It saw the rise of scholars with enlightenment thoughts such as Hobbes, Locke and Rousseau, and Voltaire, who criticized the establishment concept of government which was autocratic,and absolute. The monarchs claimed a divine essence. The enlightenment scholars placed liberties and freedoms in the core of their thoughts and led to the rise of the concept of government by consent which lay the foundation for modern day democracy.
~ Montesquieu, known as the Balanced Democrat would be the best choice.
Montesquieu did not describe a social contract as such. But he said that the state of war among individuals and nations led to human laws and government.
Montesquieu wrote that the main purpose of government is to maintain law and order, political liberty, and the property of the individual. Montesquieu opposed the absolute monarchy of his home country and favored the English system as the best model of government.
Montesquieu somewhat misinterpreted how political power was actually exercised in England. When he wrote The Spirit of the Laws, power was concentrated pretty much in Parliament, the national legislature. Montesquieu thought he saw a separation and balancing of the powers of government in England.
Montesquieu viewed the English king as exercising executive power balanced by the law-making Parliament, which was itself divided into the House of Lords and the House of Commons, each checking the other. Then, the executive and legislative branches were still further balanced by an independent court system.
Montesquieu concluded that the best form of government was one in which the legislative, executive, and judicial powers were separate and kept each other in check to prevent any branch from becoming too powerful. He believed that uniting these powers, as in the monarchy of Louis XIV, would lead to despotism. While Montesquieu’s separation of powers theory did not accurately describe the government of England, Americans later adopted it as the foundation of the U.S. Constitution.
I would say 30,000 cause all the next developments were from the 1860's forward and that is when huge growth happened, after 1860.
