Hmmm....reminds me of an idea I thought up once, the survival of the Emirate of Granada and it's rise to becoming an economic trading empire. Unfourtantly you are looking for different material so instead how about this: The Osmanoğlu (A.K.A Ottoman Empire) unite with many of the surrounding Islamic states and are able to muster more support from them. This in turn would allow the Ottomans to defeat the Timurid Dynasty at the Battle of Ankara. After a swift and devestating campaign through Mesopotamia and Persia, the Timurids are rendered useless. Now turning there attention back to the Byzantines, Bayezid I of the Ottoman Empire would begin his conquest of Europe starting with the capture of the city that managed the Byzantines, Constantinople. Thats as far as I go, but if you want a TL that focuses on a early and more succesful Ottoman invasion of Europe, this should at least give you some help on what to think about..
