[2] Ballala Sena married Ramadevi, a princess of the Western Chalukya Empire (who ruled from what is the modern Indian state of Karnataka) which indicates that the Sena rulers maintained close social contact with South India.
According to a tradition in Bengal recorded in the Ballala-charita, Ballala Sena's Empire consisted of 5 provinces,[4] Some sources exaggeratedly claim that Ballal Sen had proceeded to Delhi, and was proclaimed emperor of Hindoostan.
Ballala Sena is associated with the revival of orthodox Hindu practices in Bengal, in particular with the establishment of the reactionary tradition of Kulinism among Brahmins and Kayasthas.
His marriage to Ramadevi, the Chalukya princess also indicates that the Sens maintained the kingdom inherited from his father, which included the present day Bangladesh, the whole of West Bengal and Mithila, i.e., portions of North Bihar.
According to a cryptic passage in Adbhuta Sagara, Ballala Sena, along with his queen, retired in his old age to the confluence of the Ganges and the Yamuna leaving his son, Lakshmana Sena, with the task of both maintaining his kingdom and completing his literary work.
