James Madison was responsible for proposing the Second Amendment
and was one of three authors of the Federalist Papers, a group of essays published in newspapers to explain and lobby for ratification of the Constitution.
In Federalist Paper 46, James Madison argued that a standing federal army could not be capable of conducting a coup to take over the nation. He estimated that based on the country's population at the time, a federal standing army could not field more than 25,000 - 30,000 men. He wrote:
To these would be opposed a militia amounting to near half a million of citizens with arms in their hands, officered by men chosen from among themselves, fighting for their common liberties, and united and conducted by governments possessing their affections and confidence."
"Besides the advantage of being armed, which the Americans possess over the people of almost every other nation, the existence of subordinate governments, to which the people are attached, and by which the militia officers are appointed, forms a barrier against the enterprises of ambition, more insurmountable than any which a simple government of any form can admit of. Notwithstanding the military establishments in the several kingdoms of Europe, which are carried as far as the public resources will bear, the governments are afraid to trust the people with arms."
