What brought an end to islam’s golden age? muhammad’s death justinian’s rule the umayyad dynasty the mongol invasion

The correct answer is - the Mongolian invasion.

The Mongols were the ones that put end to the Islamic domination in the Middle East and Central Asia. The Mongol leader, Temudzin, better known as Genghis Khan, did not planed to attack the Islamic Caliphates, but instead he wanted to have nice relation with them and trade with them. But the ruler of Quaresmia made a huge mistake, he killed the messengers that Genghis Khan sent there in order to bring in collaboration between the empires. Genghis Khan had his own rule, that no messenger should be killed because they only deliver messages and are not responsible for anything. When he saw what was done to them, Genghis Khan was furious, and he unleashed most of his horde in attack, and gave them the order to kill, rob, and burn, and that what they did, and totally destroyed the Islamic Caliphates, putting an end to the Islamic Golden Age.
