between two or more states/countries that includes a promise by the signatories not to engage in military action against each other. Such treaties may be described by other names, such as a treaty of friendship or non-belligerency, etc. Leeds, Ritter, Mitchell, & Long (2002) distinguish between a non-aggression pact and a neutrality pact. They posit that a ''non-aggression pact'' includes the promise not to attack the other pact signatories, whereas a ''neutrality pact'' includes a promise to avoid support of any entity that acts against the interests of any of the pact signatories. The most readily recognized example of the aforementioned entity is another country, nation-state, or sovereign organization that represents a negative consequence towards the advantages held by one or more of the signatory parties.

History

In the 19th century neutrality pacts have historically been used to give permission for one signatory of the pact to attack or attempt to negatively influence an entity not protected by the neutrality pact. The participants of the neutrality pact agree not to attempt to counteract an act of aggression waged by a pact signatory towards an entity not protected under the terms of the pact. Possible motivations for such acts by one or more of the pacts' signatories include a desire to take, or expand, control of economic resources, militarily important locations, etc. The 1939
