1115 (Roman numeral MCXV) was a common year beginning on Friday in the Julian calendar; contemporary chronicles and later calendars record it within the framework of medieval regnal lists and ecclesiastical dating. For a modern layout of the sequence and weekdays scholars often refer to reconstructions of the full calendar and to studies of the Julian calendar in use across Europe and the Mediterranean at the time.

Overview and political context

The year falls in the period historians call the High Middle Ages, a time of territorial consolidation, active religious institutions, and long-distance networks of trade and diplomacy. Across western and central Europe monarchs, nobles and bishops negotiated power within feudal systems; in the Mediterranean and the Levant, the Crusader states established after 1096 continued to shape regional politics; in the Islamic world a number of dynasties controlled different provinces, while in East Asia competing states adjusted to new dynastic changes.

Regional highlights

  • East Asia: One of the clearest dated events of 1115 was the foundation of the Jurchen-led Jin dynasty by the chieftain Wanyan Aguda, an action that set in motion large-scale changes in northern China and in relations with the Song dynasty.
  • Europe: Feudal monarchies continued to develop institutions of governance, and Romanesque architecture and monastic reform movements remained culturally prominent.
  • Middle East and Mediterranean: The political map included both Crusader principalities and a patchwork of Muslim states and caliphates, with active trade and diplomatic exchange across the region.
  • North Africa and Iberia: North African dynasties exerted influence in the western Mediterranean and on the Iberian Peninsula, contributing to military and cultural interactions.

Beyond battlefield or dynastic headlines, the early twelfth century saw growing urbanization in some regions, expansion of long-distance trade routes, and the continued importance of monastic centers as hubs of learning and manuscript production. Architectural styles such as Romanesque spread across Europe; in scholarship, cathedral schools and emerging universities provided environments for intellectual exchange that would expand further later in the century.

When consulting records for a specific year like 1115, historians rely on chronicle entries, legal documents, coinage and archaeological evidence to reconstruct events and to place local developments within larger patterns. The year is best understood as a point in ongoing processes—dynastic change in East Asia, institutional consolidation in Europe, and continued cultural connectivity across continents.
