Theravada Buddhism has prospered in Lan Na during the reign of the religious king Kue Na, who establishes the dhatu of Doi Suthep in 1386.

Kue Na promots the Lankawongse sect and invites monks from Sukhothai to replace the existing Mon Theravada Buddhism that Lan Na had inherited from Haripunchai.

At the ascension, in 1387, of fourteen-year-old Saenmuengma (which means ten thousand cities arrive—to pay tribute) to the throne of the northern Thai mountain kingdom, his uncle, Prince Phrohm, begins plotting to seize the crown.

Failing in this, he calls upon Ayutthaya’s King Borommarchathirat for aid.

The Ayutthayan king, harboring secret ambitions to control Chiang Mai, dispatches an army north.

Sen Muang’s force meets the invaders near the city of Chiang Mai, defeating them at the Battle of Sen Sanuk and compelling their withdrawal from the country.

This is the first armed conflict between the two kingdoms.

Anshan, a small city in Liaodong province, in southern Manchuria, is first settled in 1387.

Sigismund of Luxembourg, son of the late Holy Roman Emperor Charles IV, marries Queen Maria of Hungary in 1387 and becomes King of Hungary.

Petru I of Moldavia profits from the end of the Hungarian-Polish union, and moves the country closer to the Jagiellon realm, becoming a vassal of Wladyslaw II on September 26, 1387.

This gesture is to have unexpected consequences: Petru will supply the Polish ruler with funds needed in the war against the Teutonic Knights, and will be granted control over Pokuttya until the debt is to be repaid; as this is not recorded to have been carried out, the region will become disputed by the two states, until it is lost by Moldavia in 1531 in the Battle of Obertyn.

A coalition of Turkmen principalities led by Karaman is formed to stem Ottoman expansion, but is defeated by Murad I near Konya in 1386-87.

Timur has ruthlessly subdued Persia to the Euphrates River by 1387.

Of note during the Persian campaign is the capture of Isfahan.

When Isfahan surrenders to Timur in 1387, he treats it with relative mercy as he normally does with cities that surrender.

However, after the city revolts against Timur's taxes by killing the tax collectors and some of Timur's soldiers, Timur orders the massacre of the city's citizens; the death toll is reckoned at between one hundred thousand and two hundred thousand.

An eyewitness counts more than twenty-eight towers constructed of about fifteen hundred heads each.

His massacres are selective and he spares the artistic and technical (e.g, engineers) elites.

Gian Galeazzo, leading the Milanese in waging an undeclared war in northern and central Italy, attempts to carve out a kingdom in northern Italy.
