By the time of Siyaka's ascention to the Paramara throne, the once-powerful
Gurjara-Pratiharas had declined in power, because of attacks from the Rashtrakutas and the
Chandelas. Siyaka's 949 CE
Harsola inscriptions suggests that he was a feudatory of the Rashtrakuta ruler
Krishna III. However, the same inscription also mentions the high-sounding
Maharajadhirajapati as one of Siyaka's titles. Based on this, K. N. Seth believes that Siyaka's acceptance of the Rashtrakuta lordship was nominal. Seth also theorizes that Siyaka was originally a Pratihara vassal, but shifted his allegiance to the Rashtrakutas as the Pratihara power declined.
Yogaraja The inscriptions of Siyaka are the earliest known Paramara inscriptions: they have been discovered in present-day Gujarat, and therefore, it appears that the Paramaras were connected with Gujarat in their early years. The Harsola inscriptions record Siyaka's village grants to two
Nagar Brahmins, after a victorious campaign against one Yogaraja. The identity of Yogaraja is uncertain: he may have been a
Chavda chief or the
Chalukya chief Avantivarman Yogaraja II. Both these rulers were vassals of the
Pratiharas, and Siyaka may have led an expedition against either of them as a Rashtrakuta subordinate. Siyaka issued the grants at the request of the ruler of Khetaka-mandala (
Kheda), who might have been a Rashtrakuta feudatory as well.
Hunas Nava-sahasanka-charita, an epic poem by the Paramara court poet Padmagupta, states that Siyaka defeated
Huna princes, and turned their
harems into a residence of widows. The fragmentary
Modi inscription also corroborates this victory of Siyaka, stating that he ruled the land "sprinkled over by the blood of the Hunas". This Huna territory was probably located in the north-western part of Malwa. Siyaka might have defeated a successor of the Huna chief Jajjapa, who had been killed by the Chalukya feudatory Balavarman in 9th century.
Chandelas Nava-Sahasanka-Charita also mentions that Siyaka defeated the lord of Rudapati. This territory appears to be same as "Rodapadi" mentioned in a fragmentary inscription found at
Vidisha; it appears that Rudapati lay on the eastern frontier of the Paramara kingdom. The conquest of Rudapati would have brought Siyaka in conflict with the
Chandela king
Yashovarman. A 956 CE Chandela inscription in
Khajuraho states that Yashovarman was the God of death for the Malavas (that is Paramaras, the rulers of Malwa region). Yashovarman extended the Chandela kingdom up to Bhasvat (Vidisha) and Malava river (possibly
Betwa) in the west. Based on these facts, it appears that Siyaka had to face a defeat against the Chandelas.
Sack of Manyakheta In 963 CE, the Rashtrakuta king Krishna III led a second expedition of northern India. The 965 CE and 968 CE inscriptions of his
Western Ganga feudatory Marasimha state that their forces destroyed
Ujjayani, a major city of the Malwa region. Based on this, historians such as
A. S. Altekar theorize that Siyaka had rebelled against the Rashtrakutas, resulting in a military campaign against him. However, K. N. Seth believes that Ujjain was under
Gurjara-Pratihara rule at this time, and Krishna III's campaign was directed against them: there is no evidence to show that Siyaka rebelled against Krishna III or faced a battle against his forces. After the death of Krishna III in , the Rashtrakuta power started declining. His successor
Khottiga, probably wary of the growing Paramara power, fought a battle against Siyaka. The battle was fought at Khalighatta on the banks of the
Narmada River. Khottiga appears to have been the aggressor in this battle, as it was fought closer to the traditional Paramara territory. Siyaka was victorious, although he lost his
Vagada feudatory Kanka (or Chachha) in the battle. After the battle, Siyaka pursued Khottiga's retreating forces to the Rashtrakuta capital
Manyakheta, and sacked that city. The Udaipur
prashasti states that Siyaka was as fierce as
garuda when he took the wealth of Khottiga in battle. This event happened in 972-973 CE, as suggested by the poet Dhanapala, who states that he wrote
Paiyalacchi-namamala when the lord of Malava was looting Manyakheta. Siyaka's victory led to the decline of the Rashtrakutas, and the establishment of the Paramaras as a sovereign power in Malwa. == Last years ==
