Overview
La Clef du cabinet des princes de l'Europe was the first newspaper published in Luxembourg. Its inaugural issue appeared in Luxembourg City on 1 July 1704, during the War of the Spanish Succession, and the publication continued monthly until July 1794. The title can be translated approximately as “The Key to the Cabinet of the Princes of Europe,” followed by a subtitle describing it as a historical and political compilation on the matters of the day. The name expressed the publication’s editorial ambition: to provide readers with information about the decisions and intrigues taking place in the governmental cabinets where European questions of war, diplomacy and peace were handled. The enterprise was established by Claude Jordan, a librarian, printer and journalist from Valence, and André Chevalier, a French printer from Bourg-en-Bresse who operated a printing press in Luxembourg City. Jordan had previously been associated with the Gazettes de Hollande in Leiden and Amsterdam. Their decision to publish from Luxembourg was directed primarily toward readers in Lorraine and the French market. At that time, there was not yet a distinct Luxembourgish newspaper market, so the publication’s commercial and editorial outlook was transnational from the beginning. The newspaper followed a regular and recognizable structure. International reports were arranged by kingdom or territory, while a section devoted to gossip and current affairs covered court ceremonies, royal hunts and dynastic births. It also included reviews of newly published books. Over time, the paper expanded its coverage of regional parliaments and printed material relating to Enlightenment thinkers who criticized absolutist government. This combination of diplomatic reporting, court information, political commentary and literary notices made it more than a simple local news sheet. For its first twelve years, the publication did not identify its editor or place of publication. It lacked a royal privilege, leaving it vulnerable to unauthorized reprinting, and it was also subject to a substantial stamp duty. In 1716, Jordan and Chevalier separated after a dispute concerning profits. Jordan moved to Paris and later published the related Suite de la clef, ou Journal historique sur les matières du temps, which continued until 1776. Chevalier secured authorization to continue La Clef du cabinet des princes, although the identity of the editor during the immediate post-Jordan period remained unclear. After 1730, Pierre Bourgeois is identified as the editor. The publication’s influence weakened after 1750 as the French newspaper regime became less restrictive and the number of competing periodicals increased. The established Gazettes de Hollande and La Clef du cabinet consequently faced a more crowded market. In 1769, La Clef du cabinet was banned after publishing critical material concerning famines. It nevertheless continued until July 1794, when publication ceased. The title occupies an important place in Luxembourg’s media history as an early example of a commercially oriented, internationally focused newspaper produced in the territory that became Luxembourg.
History
La Clef du cabinet des princes de l'Europe was founded in Luxembourg City in 1704 by Claude Jordan and André Chevalier. Jordan, born in Valence around 1659, was a librarian, printer and journalist who had previously worked with the Gazettes de Hollande in Leiden and Amsterdam. Chevalier, a French printer from Bourg-en-Bresse, operated a press in Luxembourg. Together they created a periodical intended for readers in Lorraine, then an independent territory, and for the French market. Luxembourg was the production base rather than the primary audience: a separate Luxembourgish newspaper market had not yet developed. The publication’s title announced its purpose. It presented itself as a key to the cabinets of Europe, promising access to the political decisions and court affairs behind major events. Its first issue appeared on 1 July 1704, in the context of the War of the Spanish Succession. The newspaper then appeared monthly without interruption until July 1794, making it an unusually long-lived periodical for the early modern European press. Its editorial format remained relatively stable. Reports on international affairs were organized by kingdom, and a recurring section covered court ceremonies, royal hunts and dynastic births. The newspaper also reviewed new books, giving it a literary and intellectual dimension. In later decades, coverage increasingly included regional parliaments and writings associated with Enlightenment thinkers opposed to absolutism. The result was a hybrid publication combining diplomatic reporting, political interpretation, court information and bibliographic commentary. During its first twelve years, the newspaper concealed both the editor’s name and its place of publication. The absence of a royal privilege created practical difficulties. The title was not protected from unauthorized reprinting and had to bear a heavy stamp duty. These constraints illustrate the legal and financial vulnerability of early newspapers, which operated within systems of licensing, taxation and censorship rather than under modern press protections. The founding partnership broke down in 1716 because of a dispute over profits. Jordan left for Paris, where he produced the related Suite de la clef, ou Journal historique sur les matières du temps. That continuation title survived until 1776. Chevalier continued La Clef du cabinet after receiving authorization to publish it. The identity of the editor immediately after Jordan’s departure is uncertain, but Pierre Bourgeois is associated with the editorship after 1730. The newspaper’s competitive position deteriorated after 1750. As restrictions on newspaper publishing in France gradually eased, more periodicals entered the market. This reduced the relative appeal of established titles such as the Gazettes de Hollande and La Clef du cabinet. The publication also encountered direct political pressure. In 1769 it was banned after printing critical articles about famines, demonstrating that its political reporting could bring it into conflict with authorities. Despite commercial competition and censorship, the title continued for another quarter-century. It finally stopped appearing in July 1794. Its historical importance rests not only on its longevity but also on its role as the first newspaper published in Luxembourg and as an early cross-border news enterprise. It connected Luxembourg’s printing infrastructure with French-language readers and the wider European information system at a time when news circulated through licensed presses, reprints and international newspaper networks.
