The Institut canadien de Montréal was founded on 17 December 1844, by a group of 200 young liberal professionals in Montreal, Quebec, Canada. The Institute provided a public library and debating room for its members. At the time, there were no French-language universities nor public libraries in Montreal. Between 1845 and 1871, some 136 lectures were held inside the Institute's walls. The Institute eventually came into conflict with the Roman Catholic Church over the contents of its library. Partly as a result of the dispute with the Church, the Institute eventually folded in the 1870s.
The Institute was founded in 1844 as a literary and scientific institution, for the purposes of providing a library, reading-room, and other educational purposes. Joseph Papin was the first president. In 1853, it was incorporated by an Act of the Province of Canada. At the time of incorporation, the Institute had over 500 members, a library of over 2000 volumes, and a reading-room with newspapers and periodical publications.
The Institute was the source of the ideas defended by the Parti rouge. One of its mottos was: Justice pour nous, justice pour tous; Raison et liberté pour nous, raison et liberté pour tous (Justice for us, justice for all; reason and liberty for us, reason and liberty for all).
The library contained literary works by French romantic authors, such as Victor Hugo and Alphonse de Lamartine, and Enlightenment authors, such as Voltaire and Diderot, whose writings were judged immoral by the Catholic Church. Between 1845 and 1871, some 136 lectures were held inside the institute's walls.
In 1858, an issue arose about the contents of the library. At a meeting of the Institute, some members proposed establishing a committee to review the library and to make a list of books which should not be allowed to remain in the library. This proposal was defeated by a considerable majority, which instead passed a resolution that the Institute's library did not contain any improper books, that the Institute was the sole judge of the morality of the books in the library, and that the existing committee of management was sufficient. Following this motion, a group of 158 members left the institute to found the Institut canadien-français de Montréal, which opted to obey the doctrine of the Catholic clergy and did not lend books which the Church judged immoral.
