The Seljuk Empire was a medieval Turko-Persian state that emerged in the 11th century. It played a significant role in the history of the Middle East by expanding its territory across parts of modern-day Iran, Iraq, and Turkey. The Seljuks were known for their military prowess and their ability to unite various tribes under a single banner. The Seljuk Empire is also notable for its contributions to culture and architecture. They promoted Islamic scholarship and built impressive structures, including mosques and caravanserais. Their influence helped shape the political and cultural landscape of the region, paving the way for later empires, such as the Ottoman Empire.
