The once mighty Seljuk Empire began to decline in the late 12th century due to a combination of internal and external factors. Internally, the empire faced power struggles among the ruling elite, weakening centralized authority and resulting in a fragmented and decentralized state. The weakening of central authority allowed local governors and warlords to assert more independence, leading to internal strife and disunity.
Externally, the Seljuk Empire faced increasing pressure from the Crusaders in the west and the Khwarazmian Empire in the east. The Crusades brought about significant military and economic challenges for the Seljuks, as they had to divert resources to defend their western territories. Additionally, the encroachment of the Khwarazmian Empire posed a serious threat to Seljuk dominance in the region.
The decline of the Seljuk Empire had a lasting impact on the broader Islamic world, paving the way for the rise of successor states such as the Khwarazmian and the Ayyubid dynasties. Furthermore, it marked a significant shift in the balance of power within the Islamic world, with new regional powers emerging to fill the void left by the Seljuks. Despite its decline, the Seljuk Empire left a lasting legacy in the form of architectural achievements and cultural influences that continued to shape the history of the region for centuries to come.
Overall, the declining strength of the Seljuk Empire was a complex interplay of internal power struggles and external pressures, ultimately leading to its disintegration and the rise of new powers in the Islamic world.
