Razadarit at his accession controlled only the Pegu province out of three principal Mon regions in lower Burma.

The Martaban region is ruled by Byattaba, and the Irrawaddy delta is under the rule of Laukpya of Myaungmya.

Razadarit had pardoned his aunt Mahadevi and given her Dagon in fief but he cannot buy the loyalty of his uncle Laukpya.

Laukpya, who had always ruled his fief like a king under his brother Binnya U, was not prepared to submit to his teenage nephew.

As Razadarit prepared to march to the delta in 1385, Laukpya had sought assistance from King Swa Saw Ke of Ava with the promise of submission to the rival Upper Burmese kingdom in exchange for Razadarit’s overthrow.

This had triggered civil war in Lower Burma; simultaneously, Shans in the north raid into Ava, and Burmese from Prome (Pye) stage a guerilla assault on the Mons.

Razdarit and his Mon forces, after ousting the Burmese from the fort of Myaungmya in the Irrawaddy delta area in 1391, unsuccessfully seeks an armistice with Ava. swa

Timur, campaigning relentlessly against Tokhtamysh’s Kipchak Khanate, attacks and partially sacks Tokhtamysh’s Golden Horde capital at Sarai in 1391, then supports a puppet khan in place of the fugitive Tokhtamysh before embarking on his planned invasion of Russia.

Timur leads his hundred thousand-man army from Sarai into Russia in 1391, conquering the city of Yelets (Jelec), but halts about two hundred miles short of Moscow and turns south toward Persia.

Timur’s forces invade from Russia, massacring the non-Muslim population of Tenais (Azov) in 1391.

Timur plans a face-to-face confrontation with the chronically ungrateful Tokhtamysh in the Golden Horde’s Kipchak Khanate, departing in 1391 with an army of over one hundred thousand men to discipline his former protégé and from there launch an invasion of Russia.

Timur leads his army north for more than seven hundred miles across the empty steppe north of the Caspian Sea to reach the Great Bulgar state.

Learning that Tokhtamysh and his army march on the western side of the Ural River, Timur plans an attack, though mindful that his movement necessitates marching his undersupplied army across desert regions.

He then rides west about a thousand miles, advancing in a front more than ten miles wide.

During this advance, Timur's army gets far enough north to be in a region of very long summer days, causing complaints by his Muslim soldiers about keeping a long schedule of prayers.

Tokhtamysh, seeing Timur’s army approaching his rear guard, attempts to halt the confrontation with gifts and fawning diplomatic gestures, but an implacable Timur, once betrayed, advances, boxing in Tokhtamysh's army against the east bank of the Volga River in the Orenburg region.

In the ensuing three-day Battle of the Steppes (or Kandurcha River), Tokhtamysh’s forces nearly destroy Timur’s left flank until his reserve troops, positioned at the rear of the center, encircle and break Tokhtamysh’s rear to defeat his troops, demoralized by a rumor from Timur’s camp that Tokhtamysh had been slain.

After the battle Tokhtamysh and some of his army are allowed to escape.

After Tokhtamysh's initial defeat, Timur invades Muscovy to the north of Tokhtamysh's holdings.

Timur's army burns Ryazan and advances on Moscow.

He is pulled away before reaching the Oka River by Tokhtamysh's renewed campaign in the south.

Dachau receives its charter in 1391; the town has served as a summer residence for several Bavarian princes from the twelfth century.

The Bavarian dukes had granted market privileges between 1240 and 1270.

Bayezid quickly smashes the rebels, occupies Bulgaria and installs direct Ottoman administration for the first time, and besieges Constantinople.

Europe is terrorized and Ottoman rule south of the Danube is assured; Bayezid's prestige in the Islamic world is so enhanced that he is given the title of sultan.

The Ottoman Turks capture Varna from the rebellious Bulgarians in 1391.
