Kaveri River in the context of "Wayanad district"

South India, also known as Southern India or Peninsular India, is the southern part of the Deccan Peninsula in India encompassing the states of Andhra Pradesh, Karnataka, Kerala, Tamil Nadu and Telangana as well as the union territories of Lakshadweep and Puducherry, occupying 19.31% of India's area (635,780 km or 245,480 sq mi) and 20% of India's population. It is bound by the Bay of Bengal in the east, the Arabian Sea in the west and the Indian Ocean in the south. The geography of the region is diverse, with two mountain ranges, the Western and Eastern Ghats, bordering the plateau heartland. The Godavari, Krishna, Kaveri, Penna, Tungabhadra and Vaigai rivers are important non-perennial sources of water. Chennai, Bengaluru, Hyderabad, Coimbatore and Kochi are the largest urban areas in the region.

The majority of the people in South India speak at least one of the four major Dravidian languages: Telugu, Tamil, Kannada and Malayalam. During its history, a number of dynastic kingdoms ruled over parts of South India, and shaped the culture in those regions. Major dynasties that were established in South India include the Cheras, Cholas, Pandyas, Pallavas, Satavahanas, Chalukyas, Hoysalas, Rashtrakutas and Vijayanagara. European countries entered India through Kerala and the region was colonized by Britain, Portugal and France.

The Chola dynasty (Tamil: [t͡ʃoːɻɐr]) 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.

Karur (Tamil: [kaɾuːɾ]) is a municipal corporation in the Indian state of Tamil Nadu. It is the administrative headquarters of Karur district and is administered by the Karur Municipal Corporation. It is located on the banks of the rivers Amaravathi, Kaveri and Noyyal. It is situated at about 395 km (245 mi) southwest of the state capital Chennai.

The region was ruled by the Cheras during the Sangam period and the town might have been part of the Chera capital at Vanchi-Karuvoor. It formed a part of the principal trade route between the west coast and Tamil Nadu. Archeological evidence points to Karur being a centre of trade during the Chera period. The region was ruled later by the Cholas, as evident from temple epigraphs. It was under the control of Pandyas, Vijayanagara Empire and the Madurai Nayaks across various periods in history. In the later part of the 18th century, the region came under the Kingdom of Mysore and the British East India Company annexed it to the Madras Presidency in 1799. After Indian Independence in 1947, it became pert of Madras State, the predecessor of Tamil Nadu.

The Noyyal River is a small river in Western Tamil Nadu, and a tributary of Kaveri River. It rises from the Vellingiri hills in the Western Ghats in Tamil Nadu, very closer in proximity to Kerala border, and flows through many villages and the cities of Coimbatore, and Tirupur. Then finally, the river drains into the Kaveri River at Noyyal, a village in Karur district named after the river itself. The river's basin is 180 km (110 mi) long and 25 km (16 mi) wide and covers a total area of 3,500 km (1,400 sq mi). Cultivated land in the basin amounts to 1,800 km (690 sq mi) while the population density is 120 people per km (311/mi) in the countryside, and 1000 people per km (2590/mi) in the cities. The area is known for its scanty rainfall and the development of the Noyyal River Tanks System to hold any overflow from the rains plus the water of the Northeast and Southwest monsoon season was ecologically important. Kausika river, which originates along the northern side of Coimbatore district in the Western Ghats along with its consequent streams, lake and pond systems is an important tributary of the river. The 173 km (107 mi) long tributary of the Kaveri River filled 32 tanks. These interconnecting tanks held the water flowing from the Noyyal.

Western Ganga was an important ruling dynasty of ancient Karnataka in India which lasted from about 350 to 999 CE. They are known as "Western Gangas" to distinguish them from the Eastern Gangas who in later centuries ruled over Kalinga (modern Odisha and northern Andhra Pradesh). The general belief is that the Western Gangas began their rule during a time when multiple native clans asserted their freedom due to the weakening of the Pallava empire in South India, a geo-political event sometimes attributed to the southern conquests of Samudra Gupta. The Western Ganga sovereignty lasted from about 350 to 550 CE, initially ruling from Kolar and later moving their capital to Talakadu on the banks of the Kaveri River in modern Mysore district.

After the rise of the imperial Chalukyas of Badami, the Gangas accepted Chalukya overlordship and fought for the cause of their overlords against the Pallavas of Kanchi. The Chalukyas were replaced by the Rashtrakutas of Manyakheta in 753 CE as the dominant power in the Deccan. After a century of struggle for autonomy, the Western Gangas finally accepted Rashtrakuta overlordship and successfully fought alongside them against their foes, the Chola Dynasty of Tanjavur. In the late 10th century, north of Tungabhadra river, the Rashtrakutas were replaced by the emerging Western Chalukya Empire and the Chola Dynasty saw renewed power south of the Kaveri river. The defeat of the Western Gangas by Cholas around 1000 resulted in the end of the Ganga influence over the region.

Erode district is one of the 38 districts in the south Indian state of Tamil Nadu. It was the largest district by area in the state before the formation of Tirupur district in 2009 and is the third largest by area, as of 2024. The headquarters of the district is Erode. The district is divided into two revenue divisions, Erode and Gobichettipalayam, and is further subdivided into 10 taluks.

The district is landlocked and lies towards the middle of the Indian peninsula and is bordered by the state of Karnataka to the north. The Eastern Ghats pass through the north-western part of the district, and the Western Ghats straddles the western edge. The district is watered by the Kaveri River which meets its major tributary Bhavani in the district. It covers an area of 6,036 km (2,331 sq mi), and had a population of 2,251,744 as per the 2011 census. The major spoken language is Kongu Tamil, a dialect of Tamil. Hinduism is the major religion with nearly 94% adherents.

The Western Chalukya Empire (/tʃəˈluːkjə/ chə-LOO-kyə) ruled most of the western Deccan, South India, between the 10th and 12th centuries. This Kannada dynasty is sometimes called the Kalyani Chalukya after its regal capital at Kalyani, today's Basavakalyan in the modern Bidar district of Karnataka state, and alternatively the Later Chalukya from its theoretical relationship to the 6th-century Chalukya dynasty of Badami. The dynasty is called Western Chalukyas to differentiate from the contemporaneous Eastern Chalukyas of Vengi, a separate dynasty. Before the rise of these Chalukyas, the Rashtrakuta Empire of Manyakheta controlled most of the Deccan Plateau and Central India for over two centuries. In 973, seeing confusion in the Rashtrakuta empire after a successful invasion of their capital by the ruler of the Paramara dynasty of Malwa, Tailapa II, a feudatory of the Rashtrakuta dynasty ruling from Bijapur region defeated his overlords and made Manyakheta his capital. The dynasty quickly rose to power and grew into an empire under Someshvara I who moved the capital to Kalyani.

For over a century, the two empires of South India, the Western Chalukyas and the Chola dynasty of Thanjavur fought many fierce wars to control the fertile region of Vengi. During these conflicts, the Eastern Chalukyas of Vengi, distant cousins of the Western Chalukyas but related to the Cholas by marriage, took sides with the Cholas further complicating the situation. During the rule of Vikramaditya VI, in the late 11th and early 12th centuries, the Western Chalukyas convincingly contended with the Cholas and reached a peak, ruling territories that spread over most of the Deccan, between the Narmada River in the north and Kaveri River in the south. His exploits were not limited to the south for even as a prince, during the rule of Someshvara I, he had led successful military campaigns as far east as modern Bihar and Bengal. During this period the other major ruling families of the Deccan, the Hoysala Empire, the Seuna dynasty, the Kakatiya dynasty and the Kalachuris of Kalyani, were subordinates of the Western Chalukyas and gained their independence only when the power of the Chalukya waned during the later half of the 12th century.
