Succeeding to the throne at a young age, Vijaya proved himself to be a formidable military leader, initiating a series of conquests into several surrounding kingdoms, including the powerful Bengal Sultanate.
[2] When he was a child, Vijaya's father was assassinated in a conspiracy orchestrated by the Brahman Lakshminarayana and one of Deva's queens, who placed the latter's son, Indra Manikya I, on the throne.
[4] The death of Daityanarayana curtailed the tremendous influence of the army chiefs in the kingdom's administration, allowing Vijaya to consolidate executive power in his own person.
Archers, elephants, artillery and a navy were organised and incorporated into its ranks, while military camps were established at Tripura's frontiers to better defend its sovereignty.
In line with trends occurring throughout the Indian subcontinent, cavalries became an intrinsic part of the army during Vijaya's reign, being established with the aid of Afghan soldiers.
[9][10] This realisation of Tripura's military might allowed a period of aggressive territorial conquests to be initiated, resulting in the extensive expansion of lands under Vijaya's control.
[14][note 2] He maintained relations with Mukunda Deva, the ruler of Odisha, to whom he entrusted the care of his elder son Dungar Fa.
[14][20][21] At the time of his death, Tripura had reached its greatest extent, controlling the entirety of eastern Bengal as well as the southern portion of the present-day Indian state of Assam.
