The third surviving son of John I of Aviz arrived in the riverside city. He would never sail much himself but would patronize systematic Atlantic exploration from Sagres on Portugal's southwestern tip, sending caravels down the African coast to Cape Bojador and beyond.

Seoul becomes the new capital of Joseon Korea
Yi Seonggye, now King Taejo, moved his seat from Gaeseong to the small town of Hanyang, ringed by mountains on the Han River. The site was chosen by geomantic advisors who deemed the landscape auspicious for dynastic longevity. Renamed Seoul, it would remain Korea's capital through five centuries of dynastic rule into the modern republic.
Charles VI expels the Jews of France
On a single decree, the French king ordered all remaining Jews out of his realm within three months. They were not allowed to take their wealth. The expulsion completed Philip IV's project of 1306 with greater finality, stripping France of its remaining Jewish communities. France would be officially without a recognized Jewish population for nearly four centuries.

Preceding Gutenberg by six decades, movable type was first widely used in East Asia for Confucian classics, administrative handbooks, and Buddhist sutras.
