In the fictional Star Trek universe, the Rules of Acquisition are a collection of sacred business proverbs of the ultra-capitalist race known as the Ferengi.
The first mention of rules in the Star Trek universe was in "The Nagus", an episode of the TV series Star Trek: Deep Space Nine (Season 1, Episode 10). In a later Deep Space Nine episode, "The Maquis: Part 1", Sakonna (a Vulcan) asks Quark (a Ferengi) to explain what a Rule of Acquisition is. He states, "Every Ferengi business transaction is governed by 285 Rules of Acquisition to ensure a fair and honest deal for all parties concerned... well most of them anyway."[1]
