A Thai army captures Angkor in 1353.

Contact with Ming Dynasty (1368-1644) China is renewed during the Muromachi period after the Chinese seek support in suppressing Japanese pirates, or wako, who control the seas and pillage coastal areas of China.

Wanting to improve relations with China and to rid Japan of the wako threat, Yoshimitsu accepts a relationship with the Chinese that is to last for half a century.

Japanese wood, sulfur, copper ore, swords, and folding fans are traded for Chinese silk, porcelain, books, and coins in what the Chinese consider tribute but the Japanese see as profitable trade.

Monaco had been refounded in 1215 as a colony of Genoa following a land grant from Emperor Henry VI in 1191.

Monaco is first ruled by a member of the House of Grimaldi in 1297, when Francesco Grimaldi, known as "Il Malizia" (translated from Italian either as "The Malicious One" or "The Cunning One"), and his men capture  the fortress protecting the Rock of Monaco while dressed as Franciscan monks—a monaco in Italian, although this is a coincidence as the area was already known by this name.

Francesco, however, is evicted only a few years afterwards by the Genovese forces, and the struggle over "the Rock" continues for another century.

The Grimaldi family is Genoese and the struggle is something of a family feud.

However, the Genoese become engaged in other conflicts, and in the late 1300s Genoa becomes involved in a conflict with the Crown of Aragon over Corsica.

The death of Güyük in 1248 had probably averted an impending family war.

His widow and regent, Ogul-Gaimish, attempts to hold power for Ögödei’s sons and his brother Chaghatai, but the 1251 election goes to Möngke, son of Ghengis Khan’s youngest son Tolui.

Tremendous subterranean deposits of salt are discovered in Poland in 1251.

The salt mines of Poland will lead to a vast kingdom in the sixteenth century, only to be destroyed when Germans bring in sea salt (which most of the world will come to consider superior to rock salt, which is naturally gray in various shades, resembling unpolished granite rather than the white or crystalline look of sea salt).

The Genoese in 1251 acquire the Mediterranean Sea port of Monaco on the Cote d’Azur, thought to have been originally settled by Phoenicians attracted by the natural harbor, and subsequently settled by Greeks, Carthaginians, and Romans.

Manfred, although only about nineteen years old at Frederick's death, had acted loyally and with vigor in the execution of his trust.

The reign is in turmoil, mainly due to riots spurred by Pope Innocent IV.

Manfred is able to subdue numerous rebel cities, with the exception of Naples.

The years of Alexander II’s minority feature an embittered struggle for the control of affairs between two rival parties, the one led by Walter Comyn, Earl of Menteith, the other by Alan Durward, Justiciar of Scotia.

The rivalry is a national phenomenon, and represents a larger factional conflict within the kingdom.

Comyn dominates the early years of Alexander's reign.

At the marriage of Alexander to Margaret of England in 1251, Henry III of England seizes the opportunity to demand from his son-in-law homage for the Scottish kingdom, but Alexander does not comply.
