en.wikipedia.org/wiki/Republic_of_Letters

This wording is inaccurate because a royal charter is issued by the Crown, not self-created by the organization receiving it. The Royal Society’s own archival catalogue states that "Three charters were granted to the Royal Society by its Founder and Patron, King Charles II" (dated 1662, 1663, and 1669). The Royal Society’s official history likewise describes the Society as becoming a chartered organisation and notes that its motto was adopted in its First Charter in 1662. So the Society may have developed internal statutes and governance, but it did not create or grant its own charters.

This claim is contradicted by earlier vernacular uses of the phrase.

A Bibliothèque nationale de France / Gallica result on Robert Estienne’s 1543 Latin-French dictionary says it renders “Gallice Reipublicæ” as “la république des lettres”—which is already a French translation more than a century before Bayle’s 1684 journal.

There is also an earlier Spanish vernacular form: the University of Salamanca’s record for Diego de Saavedra Fajardo’s República literaria dates the manuscript to 1612–1648 and states that the first edition was published posthumously in 1655. That means Bayle was not the first person to translate the Latin expression into a modern language, and if the article means French specifically, the 1543 dictionary evidence shows he was not first there either.

Bayle’s 1684 journal was certainly influential in popularizing the phrase, but "first translated" is too strong and is historically incorrect.
