Federalist No. 48 is an essay by James Madison, the forty-eighth of the Federalist Papers. It was published on February 1, 1788, under the pseudonym Publius, the name under which all the Federalist Papers were published. This paper builds on Federalist No. 47. In that essay Madison argued for separation of powers; here he argues that the legislative, executive, and judicial branches of government must not be totally divided. It is titled "These Departments Should Not Be So Far Separated as to Have No Constitutional Control Over Each Other".
