Doing some research, there is a concept of Liberty expressed by Federalists Founding Father James Madison in one of the Federalist's Papers. James Madison wrote: "Liberty... is essential to [factions] existence”
What Madison tried to say with that quote was that every faction was the product of a way of thinking, of a political belief system expressed with liberty. And that political factions were the result of the ideas of men who freely decided what could be the best for the country and that is why they formed factions or political parties, to support these ideas and present them to the American people.
