In the early 20th century, the rise of mass literacy and inexpensive newspapers transformed foreign policy into a matter of public concern, significantly impacting diplomatic processes. As democratic electorates became increasingly preoccupied with international affairs, public opinion began to set the parameters within which foreign policy operated.12

This shift forced statesmen to engage in "personal diplomacy" at frequent conferences, often trailed by the popular press. Governments, particularly in Britain and Germany, actively manipulated this publicity to influence public opinion in favor of their policies. These efforts included bribing the foreign press, planting stories, and utilizing public occasions for propaganda speeches aimed at foreign audiences.2

However, this environment made traditional diplomacy—which relies on compromise and long-term interests—extremely difficult. The public often viewed diplomacy as an athletic contest, focusing on immediate victories and the humiliation of opponents rather than lasting stability. Consequently, while diplomats of the era frequently deplored the effects of expanded democracy, such as intense press scrutiny and public attention, these factors became permanent, influential features of the diplomatic landscape.2
