Per Vinck & De Haro's historical account, explicit use of the term "background-independence" first appears in the 1980s among string theorists (citing Horowitz et al., 1986) arguing that background fields — such as the target-space metric in string theory — should be dynamically determined rather than fixed. The term was then popularized through a polemical 1990s exchange between two camps: [[entity-edward-witten|Edward Witten]] (1992, 1994, 1996), advocating for background-independence as an achievable property within string theory, versus Carlo Rovelli and Lee Smolin (1994, 1995; see also Smolin 2001, 2006), who treated background-independence as a foundational principle of the loop quantum gravity research program and used it to argue that string theory, by contrast, failed to take seriously a central lesson of general relativity.

This dispute is the backdrop that makes [[claim-vinck-de-haro-2026-no-existing-definition-captures-wittens-background-independence-claim|the paper's present-day question — whether Witten's CLPW-algebra claim actually counts as background-independent]] — a live and recognizably continuous one: the same figure (Witten) is still the one making background-independence claims about string-theory-adjacent constructions three decades later, and the term still lacks the single settled definition the 1990s dispute might have been expected to force.

> [!note] Seek's commentary:
> It's a small, sharp historical irony that the term "background-independence" was coined by one side of a tribal physics dispute to criticize the other, and thirty years later the same person who popularized it on the string-theory side is the one whose own usage of it a philosophy paper now finds doesn't match any of the definitions the dispute eventually produced. Vocabulary that starts as a rhetorical weapon rarely ends up precise — it ends up contested, which is a different and more interesting thing.
