Chola dynasty
The Chola dynasty was a Tamil dynasty originating from Southern India. At its height, it ruled over the Chola Empire, an expansive maritime empire. The earliest datable references to the Chola are from inscriptions dated to the 3rd century BCE during the reign of Ashoka of the Maurya Empire. The Chola empire was at its peak and achieved imperialism under the Medieval Cholas in the mid-9th century CE. As one of the Three Crowned Kings of Tamilakam, along with the Chera and Pandya, the dynasty continued to govern over varying territories until the 13th century CE.
The heartland of the Cholas was the fertile valley of the Kaveri River. They ruled a significantly larger area at the height of their power from the latter half of the 9th century till the beginning of the 13th century. They unified peninsular India south of the Tungabhadra River and held the territory as one state for three centuries between 907 and 1215 CE. Under Rajaraja I and his successors Rajendra I, Rajadhiraja I, Rajendra II, Virarajendra, and Kulothunga Chola I, the empire became a military, economic and cultural powerhouse in South Asia and Southeast Asia.
Origins
There is very little written evidence for the Cholas before the 7th century CE. The main sources of information about the early Cholas are ancient Tamil literature of the Sangam period, oral traditions, religious texts, temple and copperplate inscriptions. Later medieval Cholas also claimed a long and ancient lineage. The Cholas are mentioned in Ashokan Edicts as one of the Mauryan empire's neighbours to the South, who, thought not subject to Ashoka, were on friendly terms with him. There are also brief references to the Chola country and its towns, ports and commerce in the Periplus of the Erythraean Sea, and in the slightly later work of the geographer Ptolemy. Mahāvaṃsa, a Buddhist text written down during the 5th century CE, recounts several conflicts between the inhabitants of Sri Lanka and Cholas in the 1st century BCE.A commonly held view is that Chola is, like Chera and Pandya, the name of the ruling family or clan of immemorial antiquity. The annotator Parimelazhagar said: "The charity of people with ancient lineage are forever generous despite their reduced means". Other names in common use for the Cholas are Choda, Killi, Valavan, Sembiyan and Cenni. Killi perhaps comes from the Tamil kil meaning dig or cleave and conveys the idea of a digger or a worker of the land. This word often forms an integral part of early Chola names like Nedunkilli, Nalankilli and so on, but almost drops out of use in later times. Valavan is most probably connected with "valam" – fertility and means owner or ruler of a fertile country. Sembiyan is generally taken to mean a descendant of Shibi – a legendary hero whose self-sacrifice in saving a dove from the pursuit of a falcon figures among the early Chola legends and forms the subject matter of the Sibi Jataka among the Jataka stories of Buddhism. In Tamil lexicon Chola means Soazhi or Saei denoting a newly formed kingdom, in the lines of Pandya or the old country. Cenni in Tamil means Head.
History
The history of the Cholas falls into four periods: the Early Cholas of the Sangam literature, the interregnum between the fall of the Sangam Cholas and the rise of the Imperial medieval Cholas under Vijayalaya, the dynasty of Vijayalaya, and finally the Later Chola dynasty of Kulothunga Chola I from the third quarter of the 11th century.Early Cholas
The earliest Chola kings for whom there is tangible evidence are mentioned in the Sangam literature. Scholars generally agree that this literature belongs to the late centuries before the common era and the early centuries of the common era. The internal chronology of this literature is still far from settled, and at present a connected account of the history of the period cannot be derived. It records the names of the kings and the princes, and of the poets who extolled them.The Sangam literature also records legends about mythical Chola kings. These myths speak of the Chola king Kantaman, a supposed contemporary of the sage Agastya, whose devotion brought the river Kaveri into existence. Two names are prominent among those Chola kings who feature in Sangam literature: Karikala and Kocengannan. There are no sure means of settling the order of succession, of fixing their relations with one another and with many other princelings of around the same period. Urayur was their oldest capital. Kaveripattinam also served as an early Chola capital. The Mahavamsa mentions that a Chola prince known as Ellalan, invaded the Rajarata kingdom of Sri Lanka and conquered it in 235 BCE with the help of a Mysore army.
Interregnum
There is not much information about the transition period of around three centuries from the end of the Sangam age to that in which the Pandyas and Pallavas dominated the Tamil country. An obscure dynasty, the Kalabhras invaded Tamil country, displaced the existing kingdoms and ruled during that time. They were displaced by the Pallava dynasty and the Pandyan dynasty in the 6th century. Little is known of the fate of the Cholas in Tamil land during the succeeding three centuries. The Cholas disappeared from the Tamil land almost completely in this debacle, though a branch of them can be traced towards the close of the fifth century CE in Rayalaseema—the Telugu-Cholas, whose kingdom is mentioned by Yuan Chwang in the seventh-century CE. Due to Kalabhra invasion and the growing power of Pallavas, Cholas migrated from their native land Uraiyur to Telugu country and ruled from there as chieftains of Pallavas at least since 540 CE. Several Telugu Chola families like Renati Cholas, Pottapi Cholas, Nellore Cholas, Velanati Cholas, Nannuru Cholas, Kondidela Cholas existed and claimed descent from ancient Tamil king Karikala Chola. The Cholas had to wait for another three centuries until the accession of Vijayalaya Chola belonging to Pottapi Chola family in the second quarter of the ninth century to re-establish their dynasty as independent rulers by overthrowing Pallavas and Pandyas.Epigraphy and literature provide a few glimpses of the transformations that came over this line of kings during this long interval. It is certain that when the power of the Cholas fell to its lowest ebb and that of the Pandyas and Pallavas rose to the north and south of them, this dynasty was compelled to seek refuge and patronage under their more successful rivals. Despite their reduced powers, the Pandyas and Pallavas accepted Chola princesses in marriage, possibly out of regard for their reputation. Numerous Pallava inscriptions of this period mention their having fought rulers of the Chola country.
Imperial Cholas
The Chola Empire was founded in 848 CE by Vijayalaya, a descendant of Early Cholas.File:Raraja detail.png|thumb|left|Detail of the statue of Rajaraja I at Brihadisvara Temple at Thanjavur.
The early Chola kings expanded their territory and influence. During the early 10th century, the second Chola King, Aditya I, defeated the Pallava dynasty and Pandyan dynasty capturing Tondaimandalam and Kongu Nadu. Later Aditya's son Parantaka I defeated the Rashtrakuta dynasty in the battle of Vallala and also defeated the Pandyas.
Rajaraja I and Rajendra I would expand the dynasty to its imperial state in the 11th century, creating an influential empire in the Bay of Bengal. The Brihadeeswarar Temple was also built in this era. The Chola dynasty was at the peak of its influence and power during the 11th century.
Rajendra I conquered Odisha and Pala dynasty of Bengal and reached the Ganges river in north India. Rajendra Chola I built a new capital called Gangaikonda Cholapuram to celebrate his victories in northern India. Rajendra Chola I successfully invaded the Srivijaya kingdom in Southeast Asia which led to the decline of the empire there. He also completed the conquest of a kingdom in Rajarata within Sri Lanka and sent three diplomatic missions to China in 1016, 1033, and 1077.

The Western Chalukya empire under Satyashraya and Someshvara I tried regularly to loose itself from Chola domination, primarily due to the Chola influence in the Vengi kingdom. The Western Chalukyas mounted several unsuccessful attempts to engage the Chola emperors in war, and except for a brief occupation of the Vengi territories between 1118 and 1126, allied with Prince Vikramaditya VI. Cholas usually managed to dominate over the Chalukyas in the western Deccan by defeating them in war and levying tribute on them. With the occupation of Dharwar in North Central Karnataka by the Hoysalas under Vishnuvardhana, where he based himself with his son Narasimha I in charge of the Hoysala capital Dwarasamudra around 1149, and with the Kalachuris occupying the Chalukyan capital for over 35 years from around 1150–1151, the Chalukya kingdom had already started to dissolve.
The Cholas under Kulothunga Chola III collaborated to herald the dissolution of the Chalukyas by aiding the Hoysalas under Veera Ballala II, the son-in-law of the Chola monarch, and defeated the Western Chalukyas in a series of wars with Someshvara IV between 1185 and 1190. The last Chalukya king's territories did not even include the erstwhile Chalukyan capitals Badami, Manyakheta or Kalyani. That was the final dissolution of Chalukyan power though the Chalukyas existed only in name for the period 1135–1140. But the Cholas remained stable until 1215, and were then absorbed by the Pandyan empire and ceased to exist by 1279.
On the other hand, from 1150 CE to 1280 CE, the Pandya dynasty became the staunchest opponents of the Cholas and tried to win independence for their traditional territories. Thus, this period saw constant warfare between the Cholas and the Pandyas. Besides, the Cholas regularly fought with the Eastern Gangas of Kalinga. Moreover, under Chola's protection, Vengi remained largely independent. Cholas also dominated the entire eastern coast with their feudatories, the Telugu Cholas of Velanati and Nellore among others. These feudatories always aided the Cholas in their successful campaigns against the Chalukyas and levied tribute on the Kannada kingdoms. Furthermore, the Cholas fought constantly with the Sinhala kings from the Rohana kingdom of Sri Lanka, who repeatedly attempted to overthrow the Chola occupation of Rajarata and unify the island. But until the later Chola king Kulottunga I, the Cholas had firm control over the area. In one such instance, the Chola king, Rajadhiraja Chola II, was able to defeat the Sinhalese, aided by their traditional ally, a confederation of five Pandya princes, and kept the control of Rajarata under Chola rule. His successor, the last great Chola monarch Kulottunga Chola III reinforced the hold of the Chola territories by quelling further rebellions and disturbances in the Rajarata area of Sri Lanka and Madurai. He also defeated Hoysala generals who fought under Veera Ballala II at Karuvur. Furthermore, he also continued holding on to traditional territories in Tamil country, Eastern Gangavadi, Draksharama, Vengi, and Kalinga. However, after defeating Veera Ballala II, Kulottunga Chola III entered into a marital alliance with him through Ballala's marriage to a Chola princess, which improved Kulottunga Chola III's relationship with the Hoysalas.
