Timur also came to Ottoman-Turks
When some Arabs from Timur ruled areas fled into the Ottoman lands for refuge, Timur sent a letter to Ottoman-Turks ruler Yildirim Beyazid known as (Yildirim Thunderbolt) to send those men back to be punished, He offended Beyazid with this then Beyazid told him "where have you ever seen that we hand out those who seek refuge from us?" He continued "Dont make mistake to confuse us with some Indian soldiers Dont forget that you are now dealing with the Turkish army! And he welcomed Timurs army to come to the battlefields.
When Timur and his enourmous army arrived to Ankara Beyazid was awaiting him already two Turkish armies stood infront of eachother, Timur had even brought elephants with him, both gave the orders to attack and soon after the battle started in no time Beyazid saw his army getting wiped. Towards the end when almost no Ottoman army left Beyazid and his last 300 elite guards charged to the Timurs army. And he fought like a true Turk until he got captured and brought infront of Timur.
Later they became friends, when Beyazid died Timur cried and said we lost a great mujahid.
Timur was a really badass Of the Turks.
