1381 - A Zoroastrian priest fleeing Persia finds his way into Central Asia, where he converts the Khan and Timur to Zoroastrianism. This proves to be a very bloody decision, when a civil war between Muslims and Zoroastrians begins. The common person is only able to do nothing as they are recruited by nobles to fight.
1382 - The Khan of the Golden Horde, Tokhtamysh, razes the city of Moscow to the ground. However, he returns home to find a menace in the form of the Chagatai Khanate. He supports the Islamic belligerent in the civil war.
Timur scores a series of victories near Bukhara. This leads to a decline in Islamic support. Many nobles call upon the Avesta and convert to Zoroastrianism. However, many suck Muslims flee southward to the Ilkhanate, which begins to support the Islamic side more openly. A jihad is called against the forces of Timur by the Mamluk sultans.
1383 - The multi-ethnic army of Timur, based around merit rather than background, proves to crush the armies of Islamic peoples. Following this victory, Timur declares himself a shahanshah. This is seen as the beginning of the Timurid Empire.
Tokhtamysh declares war on the Chagatai Khanate and successfully overruns Azerbaijan. This proves to be simple because Timur begins his invasion of Persia, gradually converting the nation to Zoroastrianism. He swiftly conquers Khorasan, which he discovers has not been completely converted to Islam. People still have memories of their polytheistic religion. As a result, Zurvanism, or dualist Zoroastrianism, becomes the religion of the Timurid Empire to distance themselves from Islam.
1384 - Muscovy is attacked by Timur's forces while Azerbaijan is retaken. There is a return to the status quo ante bellum, while an uneasy peace settles temporarily while Persia is invaded by Timur's forces. Both sides know who will win.
The entirety of Khorasan is taken. The people of Herat are slaughtered for a refusal to convert and surrender.
1385 - The entirety of Eastern Persia is conquered. The conversion in other parts of the empire proves to be bloody, but after conversion, that region of the empire becomes more pro-Timur.
Even during Timur's conquest of Persia, Tokhtamysh attacks Azerbaijan again. He is defeated and Timur's forces reach Muscovy in the same year. But the war continues on, despite considerable support by the Zoroastrian populace of Persia.
1386 - Islamic Rebellion begins. In Persia, many crypto-Muslims violently attacked their Zoroastrian Persian nobility. Many Persian cities are turned into rubble, as the many rebel cities are easily destroyed by Timur's troops.
1387 - Remainder of Persia conquered. Notably, many nobles converted to Zoroastrianism to avoid the horrors of being a Muslim in Timur's empire. However, the city of Isfahan is an exception to this rule. The proud Muslim merchants and nobles are slaughtered and the city turns to rubble.
