Overview

The year MCCCLXXIII corresponds to 1373 in the Anno Domini system. It was a common year beginning on Saturday in the Julian calendar; a depiction of its arrangement of days can be seen in the full calendar. As part of the late 14th century, 1373 falls within the period historians call the Late Middle Ages, an era marked by political conflict, demographic recovery after the Black Death, and cultural change across Eurasia.

Political and military context

1373 was shaped less by a single defining event than by continuing regional dynamics. In Western Europe the long-running struggle between England and France known as the Hundred Years' War persisted, influencing diplomacy and military commitments. In the eastern Mediterranean and Balkans the Ottoman emirate continued to expand into former Byzantine and Balkan territories, altering the balance of power in southeastern Europe. In East Asia the newly established Ming dynasty was consolidating authority after replacing the Yuan dynasty earlier in the century.

Diplomacy and alliances

During this period rulers and states negotiated treaties and marriage alliances to secure borders and trade. Notably, an agreement reached between England and Portugal in the early 1370s is commonly cited as the origin of the Anglo–Portuguese alliance, a long‑lasting diplomatic relationship that has been highlighted by historians as among the oldest in continuous effect. Such accords exemplify how smaller and larger powers sought stable partnerships amid wider instability.

Society, economy and culture

Societies in 1373 were still adjusting to demographic and economic shifts stemming from the mid‑century plague years. Agricultural practices, labor arrangements, and urban life were changing unevenly across regions. Culturally, Gothic architecture and manuscript production remained important in Europe, while manuscript culture and court patronage continued to support literature, law and learning. Trade networks—from the North Atlantic to the Indian Ocean—continued to transmit goods, ideas and technologies.

Significance and legacy

Although 1373 does not stand out for a single universally renowned event, it sits inside a transformative century. The diplomatic ties, military pressures, and social adjustments of this year contributed to longer trends that shaped late medieval Europe and the broader premodern world: evolving state institutions, shifting trade patterns, and cultural developments that set the stage for later changes in the 15th century.
