A fight or war that goes on for so long that the people don't know, or don't need to know, what they're even fighting about
Alternate Titles: Forgotten Feud (but could be construed to have to be personal, like a family feud) - Endless War (but some people are pedantic about whether it's appropriate to call it endless or Seemingly Endless War if it ever gets resolved) Some wars begin and end fairly quickly in a few years or less. Even longer conflicts, some of the first fighters will retire from combat and then in their older years learn that the conflict finally came to an end, or they'll live through it until they become Grizzled Veterans still fighting the good fight in a Bad Future. But then there are some battles that go on so long that your children, and your children's children, and their children's children keep fighting until generations later they don't care about the history, or maybe at this point have no way of knowing what began the conflict. But either for their family's honor, or the pride of the nation, because the war affected them personally, or maybe because it was the life they were born into and fighting is all they have ever known, they get involved and are determined to fight to the death. In Real Life these are sometimes referred to as Entrenched Conflicts, where the reasons that began the conflict may have been forgotten, or shifted over time and there is no easy end in sight.
