Federalist No. 7, titled "The Same Subject Continued: Concerning Dangers from Dissensions Between the States", is a political essay by Alexander Hamilton and the seventh of The Federalist Papers. It was first published in the Independent Journal on November 17, 1787, under the pseudonym Publius, the name under which all The Federalist Papers were published. It is one of two essays by Hamilton advocating political union to prevent the states from going to war with one another. Federalist No. 7 continues the argument that was developed in Federalist No. 6. Federalist No. 7 provides several examples of disputes that Hamilton argues will cause war between the states if they do not unify under a federalist government. It presents arguments for why territorial disputes, commercial policy, public debt, and violation of private contracts would cause war between the states. Though such a war is no longer recognized as a significant possibility in the 21st century, Federalist No. 7 describes many economic issues that have continued relevance to interstate commerce.
