What did James Madison do to be the father of the constitution?

Answer 1

James Madison became father of the constitution for a few reasons, first he wrote down almost every event that happened in the writing of the constitution, second he was the one who came up with the idea for three branches of government, even though it was Edmund Randolph who suggested the idea at the convention, Madison was the one who told Randolph to suggest the plan at a pub the night before, this three branch form of government was the basis for most of the constitution, and it was for these reasons that Madison was named father of the constitution.
