simultaneously. A great battle was fought at Maski in the Raichur Doab in
which the Cholas claimed victory. In Vengi, the Chola forces defeated
Vijayaditya and the latter took shelter under Jayasimha.
Somesvara I The accession of Somesvara I ushered in a brilliant period in
the history of the Chalukyas of Kalyani which ultimately reached the zenith
of power and glory in the reign of his son Vikramaditya VI. But Somesvara’s
reign was marked by protracted struggles with the Cholas. He removed the
capital from Manyakheta to Kalyani and adorned it with many new buildings.
    Soon after his accession, Somesvara launched upon a fresh attack of
Vengi. This brought upon him the invasion of the Cholas. Rajadhiraja
defeated the western Chalukya forces, but Somesvara made a dramatic
recovery and drove the Chola forces out of his territory. Hostilities were soon
renewed and a grim battle was fought at Koppam (Kopbal), in which
Rajadhiraja fell but his son Rajendra II rallied the forces and turned the defeat
into victory.
    Despite his preoccupations with the Cholas, Somesvara found time to
engage in hostilities with other powers. He not only conquered north Konkan
but also invaded Gujarat and Malava and received the submission of the
Paramara Bhoja after a raid on his capital Dhara. Somesvara I had four sons
of whom he appointed his eldest, Somesvara II as his successor.
Somesvara II He ruled for a short period of eight years which witnessed a
struggle between him and his younger brother Vikramaditya VI. Finally
Vikramaditya killed his elder brother and ascended the throne in AD 1076.
Bilhana’s Vikramankacharita justifies his patron’s action on the ground that
Somesvara II was a cruel king who oppressed his subjects.
Vikramaditya VI Vikramaditya VI also had to face the revolt of his
younger brother Jayasimha, who was eventually defeated. More serious
danger, however, came from the Hoyasala fuedatories. Vikramaditya’s reign
saw the rule of four Hoyasala chiefs, namely Vinayaditya, Ereyanga, Ballala I
and Vishnuvardhana. The first three chiefs maintained cordial relations with
the suzerain. With the accession of Vishnuvardhana who was a great soldier
and an ambitious monarch, the process of expansion was accelerated at the
expense of the Cholas and Chalukyas. Several battles were fought, but
ultimately Vishnuvardhana made his submission.
