History of JapanThe first human inhabitants of the Japanese archipelago have been traced to the Paleolithic, around 38-40,000 years ago. The Jōmon period, named after its cord-marked pottery, was followed by the Yayoi period in the first millennium BC when new inventions were introduced from Asia. During this period, the first known written reference to Japan was recorded in the Chinese Book of Han in the first century AD. Around the 3rd century BC, the Yayoi people from the continent immigrated to the Japanese archipelago and introduced iron technology and agricultural civilization.

Mongol invasions and conquestsThe Mongol invasions and conquests took place during the 13th and 14th centuries, creating history's largest contiguous empire, the Mongol Empire (1206–1368), which by 1300 covered large parts of Eurasia. Historians regard the Mongol devastation as one of the deadliest episodes in history. In addition, Mongol expeditions may have spread the bubonic plague across much of Eurasia, helping to spark the Black Death of the 14th century. The Mongol Empire developed in the course of the 13th century through a series of victorious campaigns throughout Eurasia.
