European colonisation (1750–1850):

The East India Company (also known as the East India Trading Company, English East India Company, and, after the Treaty of Union, the British East India Company) was an early English joint-stock company that was formed initially for pursuing trade with the East Indies, but that ended up trading mainly with the Indian subcontinent and China. The oldest among several similarly formed European East India Companies, the Company was granted an English Royal Charter, under the name Governor and Company of Merchants of London Trading into the East Indies, by Elizabeth I on 31 December 1600. After a rival English company challenged its monopoly in the late 17th century, the two companies were merged in 1708 to form the United Company of Merchants of England Trading to the East Indies, commonly styled the Honourable East India Company, and abbreviated, HEIC; the Company was colloquially referred to as John Company, and in India as Company Bahadur (Hindustani bahadur, "brave"/"authority").

The East India Company traded mainly in cotton, silk, indigo dye, saltpetre, tea, and opium. The Company also came to rule large areas of India, exercising military power and assuming administrative functions, to the exclusion, gradually, of its commercial pursuits; it effectively functioned as a megacorporation. Company rule in India, which effectively began in 1757 after the Battle of Plassey, lasted until 1858, when, following the events of the Indian Rebellion of 1857, and under the Government of India Act 1858, the British Crown assumed direct administration of India in the new British Raj. The Company itself was finally dissolved on 1 January 1874, as a result of the East India Stock Dividend Redemption Act.

The Company long held a privileged position in relation to the English, and later the British, government. As a result, it was frequently granted special rights and privileges, including trade monopolies and exemptions. These caused resentment among its competitors, who saw unfair advantage in the Company's position. Despite this resentment, the Company remained a powerful force for over 200 years.

Rule of Nizams and Nawabs

European settlements began to appear in the Tamil country during the Vijayanagara Empire. In 1605, the Dutch established trading posts in the Coromandel Coast near Gingee and in Pulicat. The British East India Company built a 'factory' (warehouse) at Armagaon (Durgarazpatnam), a village around 35 miles (56 km) North of Pulicat, as the site in 1626. In 1639, Francis Day, one of the officers of the company, secured the rights over a three-mile (5 km) long strip of land a fishing village called Madraspatnam from the Damarla Venkatadri Nayakudu, the Nayak of Vandavasi. The East India Company built Fort St George and castle on an approximate five square kilometre sand strip. This was the start of the town of Madras. The coromandel coast was ruled by the Vijayanagara King (Aravidu Dynasty), Peda Venkata Raya, based in Chandragiri and Vellore Fort. With his approval the English began to exercise sovereign rights over their strip of land.

In 1675, a column of Bijapur army came to Thanjavur to help Vijayaraghava and retrieved Vallam from the Madurai Nayak. However the same army subsequently killed Vijayaraghava Nayak and Ekoji managed to ascend the throne of Thanjavur kingdom. Thus began the Maratha rule of Thanjavur. After Ekoji, his three sons namely Shaji, Serfoji I, Thukkoji alias Thulaja I ruled Thanjavur. The greatest of the Maratha rulers was Serfoji II (1798–1832 ). Serfoji devoted his life to the pursuit of culture and Thanjavur became renowned as a seat of learning. Serfoji's patronised art and literature and built the Saraswati Mahal Library at his palace. The incursion of the Muslim armies from the north forced a southward migration of Hindus from the central Deccan and the Andhra countries to seek shelter under the Nayak and the Maratha kings. The famous Carnatic music composer Tyagaraja (1767–1847), along with the Trinity of Carnatic music flourished in the Thanjavur district during this time.

With the demise of the Mughal Emperor Aurangzeb in 1707, his empire dissolved amidst numerous succession wars and the vassals of the empire began to assert their independence. The administration of the southern districts of Tamil Nadu was fragmented with hundreds of Poligars or Palayakkarars governing a few villages each. These local chieftains often fought amongst each other over territory. This turned the political situation in the Tamil country and in South India in general into confusion and chaos. The European traders found themselves in a situation where they could exploit the prevailing confusion to their own advantage.

Vijayanagar and Nayak period (1300–1650)

The 14th century invasion by the Delhi Sultans caused a retaliatory reaction from the Hindus, who rallied to build a new kingdom, called the Vijayanagara Empire. Bukka, with his brother Harihara founded the Hindu Vijayanagara Empire based in the city of Vijayanagara in Karnataka. Under Bukka the empire prospered and continued to expand towards the south. Bukka and his son Kampana conquered most of the kingdoms of southern India. In 1371 the Vijayanagar empire defeated the short lived Madurai Sultanate, which had been established by the remnants of the invading Khilji army. Eventually the empire covered the entire south India. Vijayangara empire established local governors called Nayaks to rule in the various territories of the empire.

The Vijayanagar Empire declined in 1564 defeated by the Deccan sultans in the battle of Talikota. The local Nayak governors declared their independence and started their rule. The Nayaks of Madurai and Thanjavur were the most prominent of them. Ragunatha Nayak (1600–1645) was the greatest of the Tanjavur Nayaks. Raghunatha Nayak encouraged trade and permitted a Danish settlement in 1620 at Tarangambadi. This laid the foundation of future European involvement in the affairs of the country. The success of the Dutch inspired the English to seek trade with Thanjavur, which was to lead to far-reaching repercussions. Vijaya Raghava (1631–1675) was the last of the Thanjavur Nayaks. Nayaks reconstructed some of the oldest temples in the country and their contributions can be seen even today. Nayaks expanded the existing temples with large pillared halls, and tall gateway towers, which is representative of the religious architecture of this period.

In Madurai, Thirumalai Nayak was the most famous Nayak ruler. He patronised art and architecture creating new structures and expanding the existing landmarks in and around Madurai. On Thirumalai Nayak's death in 1659, the Madurai Nayak kingdom began to break up. His successors were weak rulers and invasions of Madurai recommenced. Shivaji Bhonsle, the great Maratha Ruler, invaded the south, as did Chikka Deva Raya of Mysore and other Muslim Rulers, resulting in chaos and instability. Rani Mangammal, a local ruler, tried to resist these invasions showing great courage.

Delhi Sultanate

Malik Kafur, a general of the Delhi Sultan Alauddin Khilji invaded and sacked Madurai in 1311.[64] Pandyas and their descendants where confined to a small region around Thirunelveli for a few more years. Ravivarman Kulasekara (1299–1314), a Chera feudatory of Kulasekara Pandya, staked his claim to the Pandya throne. Ravivarman Kulasekhara, utilising the unsettled nature of the country, quickly overran the southern Tamil Nadu and brought the entire region from Kanyakumari to Kanchipuram, under the Chera kingdom. His inscription was found in Punaamalli, a suburb of Madras.
