It emerged in the middle of the 9th century AD, covered a large part of Indian peninsula, as well as parts of Sri Lanka and the Maldives Islands. The first important ruler to emerge from the dynasty was Rajaraja Chola I and his son and successor Rajendra Chola. Rajaraja carried forward the annexation policy of his father. He led armed expedition to distant lands of Bengal, Orissa and Madhya Pradesh. The successors of Rajendra I, Rajadhiraj and Rajendra II were brave rulers who fought fiercely against the later Chalukya kings, but could not check the decline of Chola Empire. The later Chola kings were weak and incompetent rulers. The Chola Empire thus lingered on for another century and a half, and finally came to an end with the invasion of Malik Kafur in the early 14th century AD.
