A parley is a formal discussion or truce negotiation between enemies, while the Brethren Court is a fictional pirate council from Pirates of the Caribbean. In the films, the Brethren Court uses the “Right of Parley,” a code-based right, to grant a temporary, protected truce for discussions. In real history, pirates had various “codes” for their ships, and the term “parley” was a real term for a truce talk between opponents, such as in military or shipping contexts. 

Parley

• A formal discussion, truce, or negotiation between opposing sides.
• It was a right in real pirate codes that allowed a pirate to request a temporary audience with the enemy captain without being harmed during the negotiation. 

Brethren Court

• A fictional organization of pirate lords from the Pirates of the Caribbean movies.
• The court was created to resolve disputes and to govern pirates across the seas, and it would appoint a Pirate King to handle things like declaring war and parleying with adversaries. 

Historical context

• Real pirates did not have one universal “Brethren Court” or code.
• Instead, many different pirate captains would create their own ship-based codes with rules for things like treasure division and internal disputes.
• The term “parley” itself was a real historical term for a discussion or truce between enemies, not limited to pirates. 
• 
  There is no known business or landmark in Portland, Texas called “Parley Pirate Court”. The phrase is from the Pirates of the Caribbean movies, where invoking the right of “parley” allows a temporary truce for negotiation between enemies. The pirate code is treated more as a guideline than a hard rule by characters in the films, notably Captain Barbossa. 
  
  Interpretation of the query
  The search results suggest the user may be asking for information related to pirates, or searching for a themed business that does not exist in the specified location. 
  For fans of the movies: The “Pirate Code” and “Brethren Court” were fictional parts of the films, which established the rule of parley.
  For real-world pirate lore: In actual history, a parley was a discussion or conference, especially between enemies over terms of a truce. It is derived from the French word parler (“to speak”). While historically the concept of a parley did exist, the specific “right of parley” as depicted in the films was not a part of any preserved real-life pirate codes.
  Potential misinterpretation: It is possible the user is looking for a pirate-themed business near Portland, TX, which they have incorrectly named.

  Yes, a 
  parley can be called on land and has been a common practice in land-based warfare throughout history. It is not restricted to the sea, though the fictional “right of parley” in the Pirates of the Caribbean movies is a specific plot device related to pirate code. 
  
  Historical Context
  Universal Practice: Historically, the term “parley” (derived from the French parler, “to speak”) referred to any formal discussion or conference between opponents to negotiate a truce or terms of surrender.
  Military Use: In real-world military history, a parley was a recognized way to discuss a cessation of hostilities, arrange for the care of the wounded, or negotiate surrender.
  Protocols: A parley on land was typically initiated by sending a herald or a designated representative, often bearing a white flag to signal a desire for a meeting without hostility. This representative had a right to inviolability under the established, albeit often informal, laws of war and chivalry.
  Examples: Historical accounts detail numerous instances of parleys on land, such as a British drummer calling for a parley with American forces during the 1781 Siege of Yorktown to discuss the terms of surrender. 
  
  Fictional Pirate “Parley”
  The specific, inviolable “right of parley” that Elizabeth Swann invokes in the Pirates of the Caribbean films is a fictional rule from the “Pirata Codex”. While real pirates did have codes and sometimes negotiated, the cinematic rule that absolutely must be obeyed until the negotiation with the captain is complete is a dramatic invention.
