Romulan Neutral Zone

Facts

• Mutually-declared neutral buffer zone between United Federation of Planets and Romulan Star Empire (TOS: "Balance of Terror" et al.)
• Formed 2160 following end of Earth-Romulan War by mutual treaty between the two powers
  • Modifications to treaty impacting the Neutral Zone made 2311 in the Treaty of Algeron following the Tomed Incident (TNG: "The Pegasus")
• All territorial claims by both sides were declared nullified
• All outposts and bases within the Neutral Zone decommissioned
• All state-sponsored or military vessels of either party, and all citizens of either nation, banned from transit into or through the Neutral Zone
  • Exceptions granted on a case-by-case basis upon mutual consent by both governments or their representatives (TNG: "All Good Things...")
  • Entry without prior authorization grants that nation the right to seize and impound the violating starship (TAS: "The Survivor")
  • Treaty of Algeron declared explicitly that purposeful unauthorized entry into the Neutral Zone by a military power is to be considered an act of war (TNG: "The Defector")
• Civilian unaligned vessels, or state-sponsored or military vessels of a third party, allowed so long as they are not merely serving as proxy actors
  • All such vessels closely monitored by both powers
• Federation border of Neutral Zone lined with permanent observation asteroid outposts (TOS: "Balance of Terror")
  • Gravitic sensor nets were installed along the Federation border to detect entry by cloaked vessels (TNG: "Face of the Enemy")
  • This technology was later supplemented with tachyon detection grids (TNG: "Face of the Enemy")
• Both nations conduct regular patrols of their border to watch for any undetected incursions (TNG: "Brothers"; Star Trek: First Contact; DS9: "In the Pale Moonlight")
