The eastward expansion of Islamic rule under the Abbasids brought Persian influence to prominence and established Baghdad as a vital trade center. Mahmud of Ghazna's military campaigns further extended Islam into northern India, influencing the region's political landscape.
The movement of Islamic rule towards the east under the Abbasids marked a significant shift in politics and economics of the region.
Persian influences began to dominate as Baghdad emerged as a new center of trade along the Silk Roads, surpassing former Mediterranean hubs.
This eastward expansion was further highlighted in the career of Mahmud of Ghazna, who extended the reach of Islam into northern India, creating a large Islamic state that controlled strategic parts of the Silk Roads.
The probable question may be:
What role did Persian influence play in the prominence of Baghdad as a vital trade center during the Abbasid era?
