Sultan Malik Shah I, ruler of the Seljuk Empire, dies on November 19, 1092, likely from poisoning, while on a hunting trip. His death led to a period of instability and infighting within the empire, which significantly weakened the empire, contributing to the success of the First Crusade in 1098-1099.
The Seljuk Empire was a medieval Sunni Muslim state that emerged in the 11th century, controlling a vast territory across the Middle East, Anatolia, and Central Asia
