Afterwards, the Umayyad Dynasty came to power.

之后，倭马亚王朝上台。

Islam spread quickly into Central Asia through  Umayyad missionaries in the 8th century.

8 世纪，伊斯兰教通过倭马亚传教士迅速传播到中亚。

Still, many in the empire were dissatisfied with Umayyad rule and questioned the dynasty's legitimacy.

尽管如此，帝国中仍有许多人对伍麦叶王朝的统治不满，并质疑王朝的合法性。

Then the Umayyad Caliphate ousted the Visigoths.

然后倭马亚哈里发驱逐了西哥特人。

They overthrew the Umayyad caliphate in 750 CE, becoming the second great dynasty of the Islamic Empire.

他们在公元750年推翻了倭马亚哈里发，成为伊斯兰帝国的第二大王朝。

The Umayyad Dynasty then expanded the empire west to Spain and moved the capital to Damascus, because it was closer to the action, empire-wise but still in Arabia.

倭马亚王朝随后将帝国向西扩张到西班牙，并将首都迁至大马士革，因为它更接近于帝国的行动，但仍然在阿拉伯半岛。

And pretty quickly the majority of Muslims weren’t Arabs, which made it pretty easy for them to overthrow the Umayyads, which they did in 750 CE. Their replacements, the Abb(ah)sids, Abb(uh)sids?

很快，大多数穆斯林都不是阿拉伯人， 这使得他们很容易推翻倭马亚王朝，他们在公元 750 年做到了这一点。 他们的替代者， Abb(ah)sids， Abb(uh)sids？
