- Cabal.
From Fed 10: In the first place, it is to be remarked that, however small the republic may be, the representatives must be raised to a certain number, in order to guard against the cabals of a few; and that, however large it may be, they must be limited to a certain number, in order to guard against the confusion of a multitude.
From Merriam Webster:
the contrived schemes of a group of persons secretly united in a plot (as to overturn a government)
From Wikipedia:
A cabal is a group of people who are united in some close design, usually to promote their private views or interests in an ideology, a state, or another community, often by intrigue and usually unbeknownst to those who are outside their group. The use of this term usually carries negative connotations of political purpose, conspiracy and secrecy. It can also refer to a secret plot or a clique, or it may be used as a verb (to form a cabal or secretly conspire).
