What was the reason of the fall of seljuk?

The fall of the Seljuk Empire was primarily due to internal strife and fragmentation, as various factions and regional leaders vied for power, leading to a decline in central authority. Additionally, external pressures from emerging powers, such as the Crusaders and the Mongols, further weakened their control over territories. The empire eventually fragmented into smaller states, which were unable to unify against these threats, ultimately leading to its collapse.
