too many divisions in the social structure
One consistent feature found in the history of southern India was the growth of small regional kingdoms rather than large empires because of absence of vast areas of fertile land. The Chola Empire of the South emerged in the middle of the 9th century A.D., 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, Odisha and Madhya Pradesh.
