Umayyads
Yes because the Rashidun Caliphate started at 632 AD and ended in 661 AD so the Umayyad caliphate started and the Umayyad caliphate ended in 749 AD so the Abbasid Caliphate start....
661-750 AD
The Umayyads controlled Spain, North Africa, the Levant, Mesopotamia, Arabia, and Persia.
The Umayyad Caliphate was overthrown by the Abbasid Revolution in 750 AD. having lost much of their power during the Third Muslim Civil War (744-747 AD).
The Umayyads are an Arab Imperial Dynasty that ruled the first Islamic Empire from 661 C.E. to 750 C.E. and after being forced out of power in the Middle East, became the Rulers of Al-Andalus or Islamic Spain from 750 C.E. to 1038 C.E.
The Abbasids were an Arab dynasty descended from Abbas, uncle of Muhammad, who supplanted the Umayyads in ad 750.
the abbasids defeated the umayyads in the battle of the great zab in ad 750.they did this because the umayyads started ruling like kings.they started hunting and dancing and only kept the Arabs in the top position.they also made non-Arab Muslims pay more taxes than them.people became unhappy with the umayyads and that is why the abbasids started the war.
In 750 CE there was a revolution against Umayyad rule which began in eastern Iran and rapidly spread over the whole empire. The Umayyads were totally destroyed except for one prince who fled to Spain and established the Umayyad dynasty there.
It depends on what you mean by "defeated". The Umayyad armies experienced their first major loss in Poitiers, France in 732 C.E. The Umayyad Caliphate in Damascus was overthrown by the Abbassids in 750 C.E. The Umayyad Caliphate in Córdoba, Spain collapsed in 1038 C.E. with the death of Hisham III without any successors.
The Umayyads controlled all of the areas in which Muslims lived, but also controlled the dominant regions for Coptic Christians, Assyrian Christians, Donatists, Justianians, Nestorians, and Zoroastrians. They also had significant minorities of the world population of Jews and Orthodox Christians.
At their height, the Umayyads controlled 50% of the Iberian Peninsula, all of Northern Africa (mostly along the Mediterranean Coast), the entire Middle East (except the Western half of Anatolia), and parts of Iran, Turkmenistan, Afghanistan, and Pakistan. The Umayyads lost this empire rather quickly when the Abbassids led a revolution and took power in 750 C.E. Abd el-Rahman, the only surviving Umayyad fled to Andalucia (Southern Spain) and re-established the Umayyad Dynasty in Andalucia (that controlled Andalucia exclusively) for another 300 years until in 1031 C.E. Hisham III, the last Umayyad died.
