19131915

19131915 is a historiographical label used to denote the period spanning from 1913 through 1915. It is not an official era name, but a compact way for scholars, archivists, and timeline makers to reference a transitional window between the pre-war era and the early years of World War I.

The years included in 19131915 cover significant upheaval in Europe and beyond. The Balkan Wars concluded in 1913, reshaping regional borders and alliances. In 1914, the assassination of Archduke Franz Ferdinand precipitated the outbreak of World War I, setting in motion a rapid expansion of hostilities across continents. The year 1915 saw major military campaigns and battles on multiple fronts, including the Gallipoli campaign and continued trench warfare, alongside broader mobilization and war economies in participating nations.

Historiographically, 19131915 is primarily used to frame analyses of the transition from the pre-war order to the wartime state, as well as comparisons of diplomacy, technology, and society during the early phase of the conflict. It serves as a contextual descriptor in timelines, bibliographies, and regional histories, rather than a formal, widely recognized era name.
