The hapless Taila was put to death, along with other members of the Chalukya family. So, with his hands reeking with the blood of his overlord, Bijjala like another Macbeth seized the Chalukyan crown. He then shifted his capital from Mangaliveda (Mangalavada) to the royal city of Kalyana.

Bijjala's independent rule was short; it lasted from about 1162 A. D. to 1167 A. D. During these years he fought successfully against the Hoysala King Narasimha I and the Pandya Chief of Uchchangi. He also defeated the Seunas and the Cholas, and subdued the turbulent Chiefs of Andhra and Kalinga. In administration, Bijjala is said to have introduced certain innovations. According to historians, the secretaries of the heads of the administrative divisions were given greater importance and were, in fact, asked to keep watch over their superior officers. This was designed to curb the provincial intransigence. Bijjala reposed great trust in Kasapayya Nayaka, who rose to position of influence in the Kalachuri Kingdom. The great Virasaiva saint Basaveshvara was Bijjala's Chief treasurer and then Prime Minister.

During Bijjula's regime   a new city was formed by amalgamating by seven villages Gajkanahalli, Bajkanahalli, Chandankiri, Kyadgi, Khatarkiri and Kurankutti to form Bijjanhalli in 1162, which was later sanskritised to Vijaypura.( Centenary Souvenir, Bijapur Municipality 1854- 1954). They are inscription which says that Chalukyan Maha Madaleashwara, kalachuri Bijjala ruler  of Badami, who later disposed Kalyani Chalukyans, was responsible for founding city of Bijapur (Bijjanhalli) in 10-11 Century. The city came under the influence of Khilji's of Delhi by 13 century and in 1347, Bhamani Sultanate of Gulbarga conquered and by this time the city as referred as Bijapur.

Scholars like B. L. Rice had believed that Bijjala was a Jaina. This erroneous view was based on the evidence of later literary works like Chennabasavapurana of Virupaksha Pandita, Bijjalarayacharite of Dharani Pandita and the Bijjalarayapurana of Chandrasagara Varni. But epigraphical and many literary sources clearly indicate that Bijjala was a Saiva by persuasion. In fact the period saw a Saiva revival with which were associated the famous names of Ekantada Ramayya, Goggideva and Viruparasa. The Kalachuri ruler was evidently a Saiva, but of the orthodox school, and he could not stomach the revolutionary ideas and practices of Basaveshvara, his Prime Minister. This explains Bijjala's opposition to the Virasaiva movement.

Bijjala abdicated in 1167 A. D. in favour of his second son Sovideva. But that did not prevent the eruption of trouble, which shook the Kalachuri Kingdom and took Bijjala as a victim. Some scholars have argued that the trouble was political in nature, and that evil officers like Kasapayya Nayaka engineered the conspiracy. But Dr. P. B. Desai is of the opinion that Bijjala's hostilities against the Virasaiva movement provoked violent reaction, which took the form of an open rebellion. Though Basaveshvara did not sanction violence, his followers unleashed it, and Bijjala appears to have been died/murdered in 1168 A. D in the forest around Kalyani.

Bijjala's successor, Sovideva/Someswara had to confront Challenges to his powers from many sides, but the held his own, and ruled upto 1176 A. D. he was succeeded by his younger brother Mallugi, but was almost immediately overthrown by his another brother Sankama who ruled till 1180 A. D. His successors were Ahavamalla (1180-83 A. D.) and Singhana (1183-84 A. D). During this period the Kalachuri Kingdom became weak and yielded its sovereign independence to the Chalukyas, whose power, in turn, flickered for a while before going out. The Kalachuri usurpation and rule, then, was dramatic, convulsive and short-lived.

ORIGIN of the term REDDY/ REDDI and specific caste there are various theories:

The oral traditions of Reddys state (first Reddy is a charioteer who impressed the king with his courage in the battle and own some lands) that Reddy is a corruption of Ratti meaning chariot or charioteer and their ancestors were charioteers for the Rashtrakutas. The Reddys may have been early practitioners of agriculture and farming. "Reddy" is derived from the Telugu word "redu" which means farm land. Some linguists surmised the word Reddy originated from the medieval term Rattodu, which is derived from Rashtrakutudu. The Rashtrakutas / Cholas/ Kalayani Chalukyas employed wealthy local farmers to head villages and collect taxes in the empire and conferred the title of Reddy. The usage of the word Reddy specifically was first seen in the inscriptions made during the Renati Chola times, 7th century CE.Another theory relates the Reddies to the Rathis, who ruled over small principalities in the Deccan plateau before 200 BCE and before the Satavahanas and Mauryas. The Rathis left coins in northern Andhra Pradesh, Kurnool district, and near Pune. The coins are found in the levels between the megalithic and Satavahana levels in excavations.
