Politics
Politics (from , meaning "affairs of the cities") is the process of making decisions that apply to members of a group.
Political faction
Occasionally, the term "faction" is still used more or less as a synonym for political party, but "with opprobrious sense, conveying the imputation of selfish or mischievous ends or turbulent or unscrupulous methods", according to the Oxford English Dictionary. In his Dictionary, Samuel Johnson (a Tory) dismissively defined Whig as "the name of a faction". Similarly, in the tenth instalment of The Federalist Papers, James Madison defines a faction as "a number of citizens, whether amounting to a minority or majority of the whole, who are united and actuated by some common impulse of passion, or of interest, adverse to the rights of other citizens, or to the permanent and aggregate interests of the community." In plain English this is a group that pursues self-interest at the expense of the greater good.
