Malainadu. Naval expedition One of the last conquests of Rajaraja was the naval conquest of the islands of Maldives ("the Ancient Islands of the Sea Numbering 1200"). The naval campaign was a demonstration of the Chola naval power in the Indian Ocean. The Cholas controlled the area around of Bay of Bengal with Nagapattinam as the main port. The Chola Navy also had played a major role in the invasion of Sri Lanka. The success of Rajaraja allowed his son Rajendra Chola to lead the Chola invasion of Srivijaya, carrying out naval raids in South-East Asia and briefly occupying Kadaram. Personal life Rajaraja married a number of women, some of whom were Vanavan Madevi aka Thiripuvāna Mādēviyār, Dantisakti Vitanki aka Lokamadevi, Panchavan Madeviyar, Chola Mahadevi, Trailokya Mahadevi, Lata Mahadevi, Prithvi Mahadevi, Meenavan Mahadevi, Viranarayani and Villavan Mahadevi. He had at least three daughters.

From the reign of Rajaraja I until the reign of Vikrama Chola in 1133 CE, the hereditary lords and local princes were either replaced or turned into dependent officials. This led to the king exercising a closer control over the different parts of the empire. Rajaraja strengthened the local self-government and installed a system of audit and control by which the village assemblies and other public bodies were held to account while retaining their autonomy.
