Dhimmi (Non-Muslims)
The Dhimmi, or non-Muslim under Muslim occupation was required during the Umayyad Period to pay a number of taxes that were connected with his Dhimmi status. The most famous was the jizya, which was a tax that Dhimmi had to pay for Muslims for the right to not be killed where they stood for not acknowledging Mohammed's Prophecy; it was a form of humiliation. Additional taxes included the kharaj, which was a tax on non-Muslim land-holdings in the Muslim World. The kharaj was so untenable that most Dhimmi were forced to live in the cities where the tax would not be applicable. On paper, a Christian or Jew could testify against a Muslim, but in reality, such testimony was not acceptable and the attempt to defame a Muslim would receive retribution. Christians and Jews were not allowed to build new houses of worship, restore old houses of worship, proselytize in any way (this included religious debate or dialogue), or allow wine or pigs to be shown in public.
Mawali (Non-Arab Muslims)
Mawali were traditionally excluded from political and social affairs. The Umayyad in particular treated them as second-class Muslims. The evidence of this treatment was that Mawali were not allowed to have many government positions and that they were taxed whereas Arab Muslims were not taxed at all. Mawali made up an important component of the Umayyad Caliphate, especially Persians. Persia was always a high seat of culture in the Islamic Empire. As a result, ideas moved quite freely throughout Persia and Persians considered themselves to be of equal worth to Arabs.
Result
Since they treated both rather horrendously, it is not surprising that the Umayyad Caliphate fell around 100 years after its foundation due to internal strife and localized rebellion. However, most of the rebellion came out of Persian and Moroccan Mawalis who were angered over their disenfranchisement rather than the Dhimmi who did not wish to receive retribution for offending Muslims.

The Abbasids moved their capital to Baghdad because they wanted to move it closer to Damascus during the time when Umayyad's capital was Damascus. In which means that the Abbasid empire wants to overthrow the Umayyad empire.
