Year 1126 was a common year beginning on Friday of the Julian calendar. It falls within the High Middle Ages, a period of expanding states, dynastic change, and frequent military conflict across Eurasia. Contemporary chronicles mark 1126 as a year in which regional power struggles accelerated, most notably between the Jurchen Jin and the Northern Song dynasty in China, and as the moment of dynastic succession in parts of Iberia.

Major events

  • East Asia: Pressure from the Jurchen Jin intensified against the Northern Song. As Jin armies advanced from the north, the Song court altered leadership and prepared for a crisis that culminated in the fall of the northern capital and the capture of the ruling emperors the following year.
  • Iberian Peninsula: The Christian kingdoms continued internal succession and consolidation. In 1126 the realm of León and Castile passed to a new ruler, beginning a reign that would shape Iberian politics in the coming decades.
  • Across the Mediterranean and Near East: The Crusader states remained established, and European monarchs pursued customary campaigns, diplomacy and church affairs typical of the period.

Context and significance

The events of 1126 are best understood as part of broader regional transformations. In northern China the rise of the Jurchen Jin state had overturned the previous regional order created by the Liao and challenged Song sovereignty. The crisis that sharpened in 1126 would lead to large population movements and the shift of the Song court to the south, inaugurating the Southern Song period. In Iberia, succession disputes and the consolidation of Christian kingdoms laid groundwork for later Reconquista dynamics.

Notable deaths and succession

  • Queen Urraca of León and Castile, a powerful and sometimes controversial ruler whose reign involved persistent conflict with nobles and neighboring kingdoms, died in 1126. Her death cleared the way for her heir to assume power.

For calendar reference, contemporary and modern accounts often cite the year's placement in the Julian system; a typical modern entry notes that Year 1126 was a common year starting on Friday and may link to the full calendar for that year. The year is usually discussed within histories that use the Julian calendar framework.

While 1126 did not produce a single epoch-making event, it represents a hinge in regional trajectories: decisive military pressure in East Asia and dynastic change in Europe that shaped later political developments. Contemporary chronicles and later historians treat it as part of a sequence leading to larger dislocations and realignments in the 1120s and 1130s.
