High Quality Content by WIKIPEDIA articles! Republic of Letters (Respublica literaria) is the long-distance intellectual community in the late 17th and 18th century in Europe and America. It fostered communication among the intellectuals of Age of Enlightenment, or "philosophes" as they were called in France. The Republic of Letters emerged in the 17th century as a self-proclaimed community of scholars and literary figures that stretched across national boundaries but respected differences in language and culture. These communities that transcended national boundaries formed the basis of a metaphysical Republic. Because of societal constraints on women, the Republic of Letters consisted mostly of men. As such, many scholars use "Republic of Letters" and "men of letters" interchangeably.
