Treaty of Algeron

The Treaty of Algeron is a formal interstellar agreement between the United Federation of Planets and the Romulan Star Empire that establishes the Neutral Zone and forbids Federation warship transit into Romulan-held space. It functions as a legal and diplomatic constraint rather than a standing enforcement body: signatory governments and their diplomatic channels uphold its terms, and breaches convert a legal instrument into a flashpoint for political crisis and military escalation. In the current material the Enterprise's intentional transit is framed as a deliberate violation, making the treaty the immediate source of legal, moral, and strategic conflict and forcing command-level decisions about trust, caution, and the risk of all-out war.
