This category is for treaties concluded or ratified by the United States. This category uses the term “treaty” in the generic sense as defined in the Vienna Convention on the Law of Treaties, that is, an international agreement “governed by international law, whether embodied in a single instrument or in two or more related instruments and whatever its particular designation.” The term “treaty” as a matter of U.S. constitutional law denotes international agreements made by the President with the advice and consent of the Senate in accordance with Article II, section 2 of the Constitution of the United States. In addition to such “treaties”, this category covers international agreements in force that have been concluded by the Executive (a) pursuant to or in accordance with existing legislation or a prior treaty; (b) subject to congressional approval or implementation, and/or (c) under and in
accordance with the President’s constitutional powers. See also: List of United States treaties and Timeline of United States diplomatic history.
