Stupid ass governor of the empire that killed those diplomats and the Sultan failed to punish the person who done because he was too confident that he would win against the Mongols.
Sultan fled the fighting was left to his son. His son did his best to repel the Mongols but it was all in vain.
Still he inflicted some defeats against Genghis.
After the Kwarazmian Empire collapsed a lot of their Turkic warriors became mercs for the various Muslim states and the Mongols.
Basically became the wagner group of their time even terrorised the crusaders by taking Jerusalem itself. These mercs starting to become to powerful that Muslim sultans like the Ayyubids and the Seljuks of Anatolia began to fear their growing power.
Interesting piece of history.
One of the main reasons the Turk-Mongols were so successful was the singular direction and loyalty of its generals. If a general was captured and sentenced to death he died happily knowing that he served the great khan to the end. He didn't run from it and wasn't fearful of it. When you look at the dying days of the Ottomans how many times did we read about generals selling the state out? If i remember correctly was it a bosnian or albanian general of the Ottoman empire who didnt fight during the balkan wars? Basically selling the Ottoman state out?
