When did the Seljuk Turks begin and end?

The Seljuk Turks began their rise to prominence in the 11th century, particularly after the Battle of Manzikert in 1071, which opened the way for their expansion into Anatolia. Their influence peaked during the 11th and 12th centuries as they established a vast empire that stretched from Central Asia to the Middle East. The Seljuk Empire began to decline in the late 12th century, eventually fragmenting by the 13th century, with the Mongol invasions further hastening their end. The last remnants of their power effectively dissolved by the mid-14th century.
