Byzantium: Giving up Brotherly Love
A few years ago Sultan Murad made a deal with Emperor John the 5th of Constantinople to help him with his financial troubles but while the Emperor was working with the Sultan, the Sultan's son, Sauji, and the Emperor's son both led revolts to overturn their fathers. The Sultan had his rebellious son blinded and Emperor John imprisoned his son, Andronikos the 4th (pronounced: an-DRONE-ee-kos), and crowned his younger son, Manuel the 2nd as co-Emperor. Andronikos escaped and had his father and brother locked in a tower for three years. They have now escaped and apparently Manuel is a fast talker because he makes a deal with the Sultan to take back Constantinople... in exchange for an increase in tribute (cash) and the last Eastern Roman city in Asia Minor... Philadelphia... the city of brotherly love. The Emperor enters Constantinople, chasing his son, Andronikos, out.      
Tamerlane: A Man-to-Man Challenge
The Khwarezm [KWA-reh-zam] oasis had been split between the Mongols of the White Horde and the Mongols of Golden Horde but as Tamerlane was consolidating his position amongst the Mongols, Husain Sufi moved south and took the city of Urganch [UR-gahnk]. When Tamerlane demanded its return, Husain refused and was killed in the inevitable war. His brother, Yusuf Sufi, negotiated a deal that included giving over his daughter in marriage to Tamerlane's son... but... she never showed. With this sort of insincere negotiation (known in the modern day by various vulgar phrases) Tamerlane has had enough. Now he's going to take it all but something strange happens... Yusuf challenges Tamerlane to a duel, a man-to-man battle for all the marbles. Tamerlane shows up at the gates of Urganch [UR-gahnk] in his battle armor ready for a fight. Yusuf backs down. Tamerlane has unmanned Yusuf and by extension, the entire city of Urganch [UR-gahnk]. A real siege ensues and Yusuf will die in bed of disease along with many of people of the city. Tamerlane will sack the city and when they city defies him again, he will level it and plant grain over the remains. He will also leave the customary monument of skulls. (That is real. He really does that, over and over again.)
With the early death of their brother, Rudolf the 4th, the self-proclaimed Archduke of Austria, the two younger brothers, Leopold III and Albert III split up the Habsburg holdings between them. The exact holdings are set out in the Treaty of Neuberg. As the years pass, their lands will become further subdivided amongst their sons and thus subdividing their overall power. Albert's line won't last very long though and the Habsburg lands will be reunited by 1490.
