MCCLXXV

MCCLXXV (1275) was a common year in the Julian calendar that began on a Sunday. In the Gregorian chronology it corresponds to the year 1275 CE. The year falls within the High Middle Ages, a period characterized by significant political, cultural, and military developments across Eurasia.

In Europe, 1275 saw continued consolidation of feudal power. In England, the reign of King Edward I was in its early stage; his administration was focused on legal reform and the enforcement of royal authority. The Statute of Westminster, enacted a decade earlier, was still shaping the legal landscape. In France, King Philip III's death in 1270 had left his son Louis IX preoccupied with Crusader diplomacy, and 1275 was marked by continued tensions with the Holy Roman Empire over territorial claims in the Rhineland.

The Mongol Empire in the East was experiencing fragmentation after the death of the Great Khan Möngke in 1259. By 1275 the Golden Horde had established a semi-autonomous rule over former eastern territories, while the Ilkhanate in Persia handled regional conflicts with the Mamluks in Egypt. In the Hanseatic League, maritime trade in the Baltic Sea continued to flourish, and the city of Lübeck was solidifying its position as a leading commerce center.

In the realm of culture, the 13th century witnessed the flourishing of Gothic architecture. In 1275, the construction of the Notre-Dame de Soissons commenced under the direction of the architect Jean de l'Étoile. The year also saw the production of illuminated manuscripts, such as the “Codex Aureus of Saint Gallen,” which exemplifies the rich artistic traditions of the time.

Notable births in 1275 included Avicenna's contemporary, the Persian mystic Jalaluddin Rumi, and Peter III of France, who would later become king. Among the significant deaths were Emperor Go-Daigo of Japan, whose efforts to restore imperial power had sparked the Kenmu Restoration, and the Dominican preacher May Gabriel, known for her influential theological discourse.

The events of 1275 encapsulate a dynamic period of dynastic succession, territorial realignment, and cultural achievement across several major civilizations.
