During the Muslim Umayyad Caliphate, a group called the Abbasids claimed that the Umayyads were not the rightful rulers because of their poor administration and neglect for Muslim rules.
The Abbasids told everyone that the Ummayads were drinking alcohol, eating pork, and doing other un-Muslim things that violated the Qu'ran. The Abbasids promised to be better rulers, and most people, including non-Arabs, supported them.
Oh no! They are overthrowing the Ummayads!
Goodbye Umayyads! Hello Abbasids!
Welcome to the Golden Age of the Islamic Empire, right here in Baghdad!
During this time, important literature, math, and science texts from around the world were translated into Arabic.
The Abbasids were extremely knowledgeable. They invented zero to make more complex formulas, introduced the benefits of medicine and hygiene, created books used by Medical students for centuries, and created advanced irrigation systems for farming.
Politically divided factions led to the Abbasids Decline. Also, they had a shortage of qualified Arabs and lots of money, which leads to lots of problems.
