Vengi. But the Rashtrakuta power in Vengi proved to be short lived. Towards
the close of his reign, Krishna led an expedition into Malwa against the
Paramara ruler Harsha Siyaka and occupied Ujjain.
    Krishna’s reign marked the disintegration of the Rashtrakuta empire. He
was oblivious of the feudal developments likely to endanger the stability of
the empire by granting the province of Tardavadi near the heart of the empire
as a fief to Tailapa. Within a few years of Krishna’s death, Tailapa felt strong
enough to overthrow the Rashtrakutas and to lay the foundations of the
Western Chalukya empire of Kalyani.
Khottiga Krishna III was succeeded by his halfbrother Khottiga. During
his reign, the Rashtrakuta empire received a rude blow which completely
shattered its prestige. The defeat which the Paramara king Siyaka had
sustained at the hands of Krishna III, was rankling in his mind and he made
necessary preparations to avenge it. Siyaka sacked Malkhed, the Rashtrakuta
capital. Khottiga did not survive long the disgrace and was followed by his
nephew Karka II.
Karka II The prestige of the empire had suffered irreparably when Karka
II ascended the throne. Matters were worsened by the maladministration of
the new emperor. The feudatories naturally felt emboldened to challenge the
imperial authority and one of them eventually deprived Karka of his
sovereignty over the Deccan within about eighteen months of his accession.
This feudatory was Taila II (Tailapa) of the Chalukya family.
Administration
The kingship was usually hereditary and the crown usually passed to the
eldest, and sometimes to the ablest son. The yuvaraja or the heir-apparent
was selected during the lifetime of the emperor. The yuvaraja usually stayed
at the capital, helping the king in the discharge of administrative duties and
occasionally accompanying the king in military expeditions. Younger princes
were usually appointed to the posts of provincial governors.
    A group of ministers consisting of the prime minister, the foreign
minister, the revenue minister, the treasurer, the chief justice, the
commander-in-chief, and the purohita helped the king in carrying out the
administration of the empire.
    The Rashtrakuta empire consisted        partly of vassal states and partly of
