Treaties are agreements between two or more sovereign states or powers on any subject of mutual concern. A bilateral treaty or agreement is between two states. A multilateral treaty or agreement is among three or more states. A treaty can end a war, set fishing limits, arrange for international taxation, establish boundaries, limit chemical or biological testing, set up international exchanges of scholars or books, or any one of thousands of other topics. Treaties play major roles in any study of international law or foreign relations.

The Reference Section of the Main Library has a collection of texts of treaties from 1648, which is often regarded as the beginning date for the present system of nation-states, to the present. The following is a list of some of the major treaty sets and indexes available in the Section:

For further information on Native-American Treaties, search the Broward County Library's online  Library Catalog ( by performing a keyword search using the following terms: Indians of North America - Treaties or Indians of North America - Laws, Legal Status and by searching the names of specific Indian Tribes, (e.g., Seminole Indians - Treaties).

A good tool for finding references to additional Native-American treaties is the LLMC Sourcebook: Native American Collection. If the Reference Section does not have the needed resources, an Interlibrary Loan request may be made. Ask the librarians for assistance in doing this.
