As the Islamic world faced fragmentation and internal discord in the 10th century, the Seljuks found themselves at the crossroads of opportunity. During this time, many Islamic states were weakened by infighting and dynastic disputes, especially the Abbasid Caliphate, which had lost much of its real power to regional rulers and military commanders. It was within this vacuum that the Seljuks rose, not only as conquerors but also as restorers of Sunni orthodoxy, aligning themselves with the Abbasid Caliphs in Baghdad to legitimize their rule.
Their migration westward, driven by both necessity and ambition, brought them into direct conflict with established powers like the Ghaznavids and later the Byzantines. However, their success was not solely the result of military strength. The Seljuks adapted to their new environment with extraordinary political acumen, adopting Persian bureaucratic systems, embracing Islam, and promoting scholarship and infrastructure. This fusion of nomadic vigor and settled sophistication gave the Seljuk Empire a unique character that would influence many subsequent Islamic dynasties.
