Khorasan was the epicenter of the Abbasid movement (the Da'wa). The Abbasids utilized the region's distance from the Umayyad capital and the support of local Persian converts (Mawali) and disillusioned Arab tribes to launch their uprising.

With the rise of the Abbasids, the capital moved from Damascus to the newly built city of Baghdad. This signaled the start of the Abbasid Golden Age, where Persian influence and scientific advancement flourished in the new metropolitan center of Iraq.

In medieval Islamic political theory, the 'Sikka' (coinage) and 'Khutba' (mention in the Friday sermon) were the two primary signs of a ruler's legitimacy and independence. By minting their own coins, the Umayyads declared they were no longer subservient to Byzantine or Persian economic systems.

The Abbasid victory shifted the center of gravity from Syria to Iraq and integrated Persian culture and non-Arab Muslims into the core of the state. This changed the character of the Caliphate from a primarily Arab tribal kingdom into a more universal and cosmopolitan Islamic empire.

As the empire expanded, the Umayyads adopted and adapted the sophisticated administrative practices of the Sasanian (Persian) and Byzantine Empires. They retained many local bureaucrats and used their systems of bookkeeping and taxation to manage the state.

The Umayyad state was largely an 'Arab' empire. Non-Arabs who converted to Islam (Persians, Berbers, etc.) were often denied equal status, social prestige, and economic benefits. This contradiction between the universalist message of Islam and the tribal policies of the state was a major cause of the Umayyad downfall.

Yazid III (r. 744) was the son of a Persian princess, though the question's premise often points to the changing ethnic makeup of the dynasty. Marwan II, the last Umayyad caliph in the East, was actually the son of a Kurdish slave woman, illustrating the assimilation occurring within the elite.

Abd al-Malik ibn Marwan implemented the 'Arabization' of the administration, replacing Greek and Persian with Arabic as the official language of the state. This reform was crucial for unifying the diverse and expanding empire under a single linguistic and administrative framework, facilitating more efficient governance.

The resolution recognised the Nagri script, along with Persian, for official use in the courts.

The failed siege taught Muslims that not every battle ends in immediate success. Allah grants victory when He wills, and patience with trust in Him is the true path.
