The Ottoman Empire was the successor of which dynasty?

The Ottoman Empire emerged as the successor of the Seljuk Dynasty. As the power of the Seljuk Sultanate of Rum in Anatolia declined, various Turkoman beyliks (principalities) arose. One of these, led by Osman I, gradually expanded to form the Ottoman Empire around 1299, inheriting much of the Seljuk's cultural and political legacy in the region.

• The Umayyad Dynasty (661-750 AD) and Abbasid Dynasty (750-1258 AD) were earlier Islamic caliphates that preceded the Seljuks and Ottomans.
• The Fatimid Dynasty (909-1171 AD) was a Shi'ite Islamic caliphate based in North Africa and Egypt, distinct from the Sunni Seljuks and Ottomans.
