Event Summary:
The Seljuks and Ottomans were both Turkic dynasties that rose to power within the Islamic world. While the Seljuks preserved the Abbasid caliphate and defended Sunni orthodoxy during the medieval era, the Ottomans replaced the caliphate entirely and built a vast early modern empire across three continents.

Why It Matters:
The Seljuks laid the groundwork for Turkic-Islamic rule in the Middle East and Anatolia. The Ottomans inherited and expanded that legacy, transforming it into one of the most enduring empires in world history, both military powerhouse and cultural bridge between East and West.
