The Paris Peace Conference significantly altered the role of publicity in diplomacy by championing the ideal of "open covenants of peace openly arrived at," a goal famously articulated by U.S. President Woodrow Wilson as part of his Fourteen Points.12

While Wilson sought to make diplomatic results transparent—requiring treaties to be published and registered with the League of Nations—the actual process remained largely secretive, with substantive negotiations occurring in private sessions rather than public forums. Despite this, the conference marked a shift toward "publicity-driven" diplomacy, where statesmen were increasingly trailed by the press and used public occasions to influence public opinion.1

This era introduced a tension between the democratic demand for transparency and the traditional necessity of quiet negotiation. Governments began manipulating media coverage through propaganda and planted stories to sway domestic and foreign audiences. Ultimately, while the conference established a precedent for public accountability in treaty-making, the core diplomatic process remained largely unchanged, continuing to rely on secret deliberations behind the scenes.1
