During the reign of Bhima II, the Vaghelas became the de facto rulers of the Chaulukya kingdom. Inscriptions at Girnar suggest that by 1231 CE (1288 VS), Lavanaprasada had assumed the title Maharajadhiraja (king of great kings), and his son Viradhavala had assumed the title Maharaja (great king). However, the Vaghelas continued to nominally acknowledge Bhima and his successor Tribhuvanapala as their overlords.
